UHF Satellite Communication (image : Viasat)

Carlsbad, Calif. – The Commonwealth of Australia Department of Defence (ADF) has selected ViaSat Inc. (NASDAQ:VSAT) to supply the UHF Satellite Communication (Satcom) Mission System for its recently-launched UHF capacity on Intelsat IS-22. The system is designed to provide voice and data military satcom covering a region from the west coast of Africa to the east coast of Australia. The value of the award to ViaSat is approximately $35 million.

The IS-22 satellite launched March 26 with a hosted UHF payload – representing about 30 percent of the satellite’s total capacity – dedicated to ADF communications. The ability to serve small, mobile terminals used by ground, sea, and air forces in all types of terrain make UHF especially suited to military satcom.

“The Network Control System will use satellites in the Pacific and Indian Ocean regions to support the resource sharing partnership with the United States,” said Stephen Smith, AustraliaMinister for Defence. “The NCS will become a critical component for UHF communications for ADF personnel operating in the

Middle East.”

Partnering with Australian industry, ViaSat is responsible for providing a complete UHF Network Control System that includes system architecture, design, development, integration and test, site preparation, equipment procurement and installation, and ongoing support. The system is also designed to include the Integrated Waveform (IW) for channel control and network terminals, enabling an increase in channel efficiency and available bandwidth.

“I think our ability to deliver IW capability is the significant reason we were chosen for this award,” said Jerry Goodwin, VP Business Development at ViaSat. “That technology is something we feel is important to maintaining a leadership position in global UHF satcom systems and services.”

ViaSat UHF systems are installed in the U.S. and internationally, including Italy, Germany, and the United Kingdom.

BRISBANE, Queensland - Boeing has successfully demonstrated its SATCOM on the Move (SOTM) product on a live Ka-band satellite network. The demonstration in May connected three sites in Australia and the United States using integrated voice, video, and data communications over the increased bandwidth available on the latest generation Ka-band satellite mobile terminals. This capability uses the Wideband Global SATCOM (WGS) system, also developed by Boeing.

During the demonstration, High Mobility Multipurpose Wheeled Vehicles (Humvees) fitted with cameras and handheld radios successfully connected to test labs in Australia and the United States, simultaneously combining videoconferencing with military radio and telephones. The integrated SOTM demonstration proved core elements of a seamless, secure and deployable communications system.

This latest SOTM product evolved from combat-proven technologies used by the U.S. Army during Operation Iraqi Freedom in 2003.

"This demonstration shows the maturity and readiness of Boeing's capabilities in the suite of services required to provide satellite communications on the move," said Kim Gillis, vice president and managing director of Boeing Defence Australia. "Our proven SOTM technology will provide defense customers with confidence that HQ on the Move capability can be achieved on the Ka-band satellite system ready for the WGS network."

Indonesia Akan Terbitkan Satelit Baru

TEMPO.CO, Jakarta - Deputi Bidang Teknologi Dirgantara Lembaga Penerbangan dan Antariksa Nasional (LAPAN) Soewarto Hardhienta mengatakan LAPAN akan mengorbitkan satu satelit bikinan Indonesia pada Agustus mendatang.

“Itu satelit seluruhnya bikinan Indonesia,” kata Soewanto di kantor Kementerian Pendidikan dan Kebudayaan, Senin siang, 4 Juni 2012.

Satelit yang akan diorbitkan itu diberi nama LAPAN-A2. Ia mengatakan LAPAN menyertakan tiga perangkat utama dalam satelit tersebut. Perangkat pertama adalah pemotret Bumi. Nantinya Indonesia bisa memotret Bumi dari angkasa dengan satelit tersebut.

Perangkat kedua adalah pembaca sinyal kapal. Dengan perangkat tersebut, pemerintah bisa mengetahui setiap kapal besar yang memasuki wilayah perairan Indonesia. “Kapal secara otomatis mengirim sinyal yang akan ditangkap satelit,” kata Soewarto.

Kapal-kapal yang mampu dilacak oleh satelit itu umumnya adalah kapal besar. Satelit belum bisa menangkap keberadaan kapal nelayan kecil yang umumnya terbuat dari kayu. “Selama ada pengirim sinyal, bisa dilacak,” katanya.

Perangkat ketiga adalah penunjang komunikasi radio amatir. Perangkat tersebut akan sangat berguna bagi proses penanggulangan bencana. Ini untuk menjamin alat komunikasi radio amatir tetap menyala dalam situasi genting. “Kalau saat bencana, umumnya alat komunikasi konvensional mati,” ujarnya.

Satelit tersebut akan diorbitkan menggunakan sebuah roket peluncur satelit dari India. Soewarto mengatakan Indonesia belum menguasai teknologi roket peluncur satelit, sehingga pengorbitan satelit dilakukan di India.

Australia’s Military Satcom Ties With U.S. Have ‘Pitfalls’

12 Mei 2012

Singapore– The U.S.’s increasing presence in

Australia

and the Asia-Pacific region has implications for military satellite communications, says the Australian Defense Department ’s satellite capability project officer, Sqdn. Leader Daniel Howarth.

“It will mean more challenges,” as the U.S. will increasingly be using bandwidth from its Wideband Global Satcom (WGS) satellites covering the region , he notes. The U.S., however, has given assurances that Australia will have guaranteed access to the WGS network, Howarth says. But he also explains that the U.S. controls the WGS network, so Australia faces a challenge of ensuring that the U.S. sticks to its commitment and gives Australiathe access it needs.

Howarth says WGS is useful to Australia because it provides global coverage as well as the ability to focus on the country’s territory and the Pacific and Indian oceans.

Australia’s military currently uses commercial satellite Optus C1 for wideband coverage. “Having only a single satellite has created operational issues” for the military, says Howarth. Australia’s military forces in Afghanistan, for example, were unable to use C1 because the satellite provides coverage only of Australia, he says. This means Australian forces had to use commercial satellite communication providers, he adds.

Howarth was speaking at the MilSatCom conference in Singapore on May 9. One of the conference delegates asked Howarth whether the Australian military will be using the new satellites that the country is launching.

Two satellites are expected to provide the country ’s population with a national broadband network (NBN). Howarth says the military will have no payload on these satellites.

It is “a missed opportunity,” says Howarth, adding that “to put a military payload on that satellite” would have given Australia its own military satellite capability, rather than relying on spacecraft controlled by overseas parties. Howarth in this instance was expressing his own personal view and not necessarily that of Australia’s department of defense. Howarth says there was no push within the department to have a military payload on an NBN satellite.

New ADF Satellite Launched

12 April 2012

A NEW SATELLITE was successfully launched in Kazakhstan last week, which will improve communications abilities for Australian Defence Force personnel operating in the Middle East.

The IS-22 satellite was launched from Baikonur Cosmodrome in Kazakhstan. The launch was managed by Intelsat, an international satellite service provider.

The Australian Defence Force has purchased an Ultra High Frequency communications payload, which forms part of the satellite. More than 30 per cent of the satellite is dedicated to Australian Defence communications.

“This satellite means we will be able to transmit voice and data anywhere between the west coast of Africa and the east coast of Australia,” said Minister for Defence Materiel Jason Clare. “It will make it easier for commanders in Australia to provide troops on the ground with information faster and more effectively.

“It will also mean that troops can provide intelligence and information back to Headquarters.”
Currently, the ADF has limited use of United States’ satellites in this region.

The launch of the IS-22 means that Australia now has its own dedicated Defence satellite communications network in this region.

The satellite will also be used for commercial purposes, but Defence has put in place high level security measures including data encryption to protect ADF communication links.

The $269 million program has delivered the project on time and within budget. Intelsat is contracted to operate the satellite for 15 years after launch.

The Defence Force is to join a United States network of nine military satellites to improve communications between New Zealand and overseas deployments.

Defence Minister Jonathan Coleman says New Zealand joins Canada, Denmark, Luxembourg and the Netherlands in getting access to the network in return for partially paying for the ninth satellite.
Dr Coleman says that will cost New Zealand $83.2 million over the next 20 years, but will ensure better communications for military personnel deployed overseas.

The minister says until now, New Zealand has had to buy satellite bandwidth at spot prices which can involve premiums of up to 100% depending on demand.

Enhanced Communications for Deployed Forces

The Minister for Defence, Senator John Faulkner, today announced that the Government has approved a significant initiative to enhance communications support to the Australian Defence Force, including in the Middle East Area of Operations.

Under Defence Capability Plan Joint Project 2008 Phase 5A, Defence is already in the process of acquiring part of the Intelsat IS-22 UHF payload providing coverage over the Indian Ocean Region. A contract for the provision of this payload was signed with Intelsat in April 2009.

Today’s announcement involves approval to exercise the Government’s option to purchase the full ultra-high frequency (UHF) payload on the Intelsat IS-22 communications satellite at an additional cost of around $193 million. This brings the total IS-22 payload purchase cost to $475.1 million.

“Purchasing the full satellite payload will improve operational effectiveness and enhance the communications support to Australia’s deployed forces in the Middle East and Afghanistan,” Senator Faulkner said.

Coinciding with the visit by the United States Department of Defense Vice Chairman of the Joint Chiefs of Staff, General James Cartwright, Senator Faulkner also announced that Australia and the United States have signed a Memorandum of Understanding (MOU) on sharing their narrowband UHF communications resources.

“This initiative will provide the United States added communications capacity for its operations in Afghanistan by utilising the Australian payload on the IS-22 communications satellite. In turn the Australian Defence Force will gain access to communications capacity over the Pacific Ocean region from United States’ satellite resources,” Senator Faulkner said.

The UHF Communications MOU complements the Wideband Global System satellite partnership between Australia and the United States. The arrangement will result in significant savings for both nations, provide a more robust communications capability for the warfighter and add another dimension to the Australian-US Alliance.

The satellite will be launched by the Intelsat Corporation in 2012.

US Vice Chairman of the Joint Chiefs of Staff General James Cartwright and Vice Chief of the Defence Force Lieutenant General David Hurley exchanged the SATCOM MOU in Canberra today.

The Mobile User Objective System (MUOS) satellite is facing another significant delay, pushing out the availability of the US Navy's next-generation ultra-high frequency satellite until December 2011, according to a report submitted to Congress by the service's top weapons buyer.

Back in February 2007 the Australian government announced that an MoU had been agreed between the Australian Department of Defence and the US Navy, setting out the governing arrangements for a joint military communications ground station near Geraldton, Western Australia.

The purpose of the joint ground station is to support the US Navy's MUOS, a narrow-band networked satellite constellation for UHF satellite comms enabling secure all-weather and all-terrain 3G mobile telecommunications.

It is designed to support US and Australian military users including deployed forces.

The MUOS ground station is collocated with the Australian Defence Satellite Communications Ground Station at Kojarena, 30 km east of Geraldton WA, but will be managed separately.

Boeing Australia Ltd was awarded a contract to develop the MUOS compound at the Australian ground site with the station scheduled to become operational by March 2010.

However, the MUOS constellation of four geosynchronous satellites (and one spare) will not reach full operational capability until some time after 2014.

General Dynamics C4 Systems is the lead contractor for the entire MUOS ground infrastructure and GD and Ericsson are also providing the waveform technology driving MUOS capabilities.

Based on its 3G technology, Ericsson's WC DMA will be modified by GD to operate over the satellite.

It is anticipated that there will be emphasis on dismounted handheld user terminals provided under the JTRS Cluster 5 program, which is a major user of this waveform, with the same applying to future ADF users already familiar with JTRS capable radios - which will now sport 3G waveforms.

Singapore to Launch Satellite

Singapore is set to launch its own domestically built satellite, X-Sat, into space in mid 2010.

The 120kg micro-satellite will launch atop an Indian Space Research Organisation-built polar satellite launch vehicle.

X-Sat, which is being developed by Nanyang Technological University (NTU) and DSO National Laboratories, will be partly powered by solar energy and spend three years in orbit at an altitude of 800km, according to Strait Times.

Collecting images measuring soil erosion and monitoring environmental changes the micro-satellite relays information from sensors to a ground station at NTU.
X-Sat is expected to cost approximately S$40m (US$29m) and is scheduled to launch in June-July 2010.

Military Reconnaissance Satellite Launched by China

6 Maret 2010

China successfully launched another Earth observation satellite from the Jiuquan space base Friday, according to state-run media outlets.

The Yaogan 9 spacecraft blasted off from Jiuquan on a Long March 4C rocket at 0455 GMT (11:55 p.m. EST Thursday), or 12:55 p.m. local time. The three-stage rocket successfully delivered the secret payload to orbit, the state-owned Xinhua news agency reported.

The Jiuquan launch site is located in the Gobi desert near the border between China's Gansu and Inner Mongolia provinces. Jiuquan has hosted the launches of all three Chinese human spaceflights to date.

Yaogan 9 is the newest member of a series of satellites believed to harbor optical and radar military reconnaissance capabilities.

The satellite "would be used to conduct scientific experiment[s], carry out surveys on land resources, forecast grain output and help with natural disaster-reduction and prevention endeavor[s]," state media reports said.

But most experts believe the Yaogan series includes two variants with high-resolution electro-optical cameras and cloud-piercing radars designed to see targets through inclement weather or darkness.

In the past, optical Yaogan satellites launched from Jiuquan and radar-equipped spacecraft were shot into orbit from the Taiyuan space center in northern China's Shanxi province.

Before Friday's mission, analysts believed China had orbited three electro-optical Yaogan satellites and five radar payloads.

Previous Yaogan launches from Jiuquan used the less powerful Long March 2D booster. The Long March 4C launched Friday includes a restartable third stage to increase payload performance. Chinese officials did not address the change in rocket, but the more powerful launcher could indicate the mission carried an upgraded Yaogan satellite.

Official Chinese media did not announce the launch until Thursday, a typical communications procedure for closely-guarded military space missions.

Friday's launch was the second orbital flight of Chinese rockets this year, and it marked the ninth space launch to reach orbit worldwide so far in 2010.

Lapan Operasikan Stasiun Bumi di Biak

23 Januari 2010

Coverage satelit Lapan Tubsat (photo : Lapan)

Jakarta (ANTARA News) - Lembaga Penerbangan dan Antariksa (Lapan) telah mengoperasikan stasiun bumi yang dibangunnya sendiri di Pulau Biak, Papua, demikian diumumkan Lapan hari ini di Jakarta.

Para teknisi Lapan membuat stasiun bumi itu dengan mengintegrasikan komponen-komponen yang dibelinya dan membuat sebagian software (perangkat lunak) sendiri untuk mengoperasikannya.

Sebuah kemajuan karena dua stasiun bumi sebelumnya yang ada di Rumpin dan Rancabungur, Bogor, bukan dibuat sendiri tetapi dibeli dari Amerika Serikat.

Stasiun bumi Biak digunakan untuk menerima data dari LAPAN-TUBSAT, satelit mikro yang berbobot hanya 100 kilogram yang dikembangkan bekerjasama dengan Universitas Teknik Berlin, Jerman.

LAPAN-TUBSAT diluncurkan ke orbit polar dengan ketinggian 635 km di atas permukaan bumi pada Januari 2007. Dengan dua kamera, satelit itu mampu memotret berdimensi 5 meter dan lebar 3,5 km serta 200 m dan lebar 81 km.

Perangkat komunikasi tersebut telah berhasil mengambil berbagai citra di wilayah Indonesia bagian barat, mencakup Singapura hingga Bali.

Pada tahun lalu, LAPAN-TUBSAT digunakan untuk memantau pembangunan jembatan Suramadu dan proyek jalan tol di wilayah utara Pulau Jawa. Citra LAPAN-TUBSAT dapat dilihat di situs http://www.lapantubsat.org/.

Stasiun bumi Lapan di Biak memiliki antena untuk menangkap sinyal satelit berorbit rendah. Dalam menangkap sinyal satelit semacam itu, antena harus dapat bergerak atau berubah orientasi secara cepat karena satelit muncul dan hilang dari horizon dalam waktu singkat, kurang dari 15 menit.

Beroperasinya Stasiun Bumi penerima Biak menambah cakupan LAPAN-TUBSAT hingga wilayah Indonesia timur, bahkan hingga pantai utara Australia.

Keberhasilan beroperasinya stasiun bumi di Biak menunjukkan bahwa teknisi Lapan telah menguasai teknologi perekayasaan stasiun bumi untuk satelit orbit rendah.

Lapan akan membangun stasiun bumi serupa mulai awal tahun ini di Kotatabang, Sumatra Barat, sehingga menambah cakupan LAPAN-TUBSAT melampaui Aceh hingga Semenanjung Malaya.

Bila stasiun bumi Kototabang terwujud, maka hanya wilayah Indonesia bagian tengah saja yang belum tercakup LAPAN-TUBSAT. Namun, itu tidak berlangsung lama karena pada 2011 akan dibangun stasiun bumi di Parepare untuk menjangkau wilayah itu.

Defence has signed a $94 million contract for the construction of three satellite communications earth terminals that will improve global communications for deployed ADF forces.

Greg Combet, the Minister for Defence Personnel, Materiel and Science, said the new terminals will be built at the Australian Defence Satellite and Communications Station near Geraldton in Western Australia.

“The completion of the new capability in 2013 will significantly enhance the wideband strategic communications support available to Australian forces overseas,” Mr Combet said.

“This includes those forces on distant deployments in the Middle East and also on operations closer to home in the Indian and Pacific Oceans.”

The contract, awarded to BAE systems, also includes five years of support for the new terminals and an enhanced network management system to enable the terminals to be controlled remotely from HMAS Harman in Canberra.

The new facility will increase the amount of data that will be able to be provided over the Wideband Global Satellite (WGS) System that Australia accesses, through a partnership with the United States Department of Defence.

Shared space capabilities and technologies are seen as a key linchpin of Australia’s defense relationship with America, and Australia’s ISR (Intelligence, Surveillance and Reconnaissance) capabilities in general will be closely coordinated with the USA, and the US Pacific Fleet.

Australia will buy a remote sensing satellite, probably based on a high-resolution, cloud-penetrating, synthetic aperture radar. The USA will be given access to the system’s imagery. Note that India, facing a similar need, bought and launched an IAI TECSAR satellite from Israel.

Wideband Global SATCOM (image : Boeing)

The Government will continue the Wideband Global SATCOM partnership with the USA, and will accelerate decision making around the Narrowband UHF satellite communications capabilities needed to support land operations. Options include commercial capabilities, partnership in American programs like MUOS, and cooperation with other countries.

On the flip side, Electronic Warfare against enemy ships, planes, and radars is seen as a strategic priority for Australia, who will be funding several projects in this area and establishing a Joint EW Centre to coordinate efforts across all branches of the ADF.

The proliferation of satellite killers and space junk alike have led Australia to seek a focus on “space situational awareness” as the basis of research, and add a career stream for space specialists.
