MSAT

Last updated

MSAT (Mobile Satellite) is a satellite-based mobile telephony service developed by the National Research Council Canada (NRC). Supported by a number of companies in the US and Canada, MSAT hosts a number of services, including the broadcast of CDGPS signals. The MSAT satellites were built by Hughes (now owned by Boeing) with a 3 kilowatt solar array power capacity and sufficient fuel for a design life of twelve years. TMI Communications of Canada referred to its MSAT satellite as MSAT-1, while American Mobile Satellite Consortium (now Ligado Networks) referred to its MSAT as AMSC-1, with each satellite providing backup for the other.

History

[1]

Phaseout

MSAT-1 and MSAT-2 have had their share of problems. Mobile Satellite Ventures placed the AMSC-1 satellite into a 2.5 degree inclined orbit operations mode in November 2004, reducing station-keeping fuel usage and extending the satellite's useful life. [7]

On January 11, 2006, Mobile Satellite Ventures (MSVLP) (changed name to SkyTerra, then became by acquisition LightSquared, then after bankruptcy Ligado Networks) announced plans to launch a new generation of satellites (in a 3 satellite configuration) to replace the MSAT satellites by 2010. MSV has said that all old MSAT gear would be compatible with the new satellites. [8] [9]

The following services are singularly dependent upon the continued operation of the MSAT satellite:

TransOrbital is a California-based company which became the first private company granted permission by the U.S. government to explore, photograph, and land on the Moon. The company has been covered in over 2,000 news articles worldwide, and announced a sponsorship agreement with Hewlett-Packard in 2003. The company planned to launch the TrailBlazer lunar orbiter, which was proposed as the first privately-financed science mission to the Moon. The Trailblazer will provide live streaming video of the entire mission, pictures of Earth from space, detailed maps of the full Moon surface, photographs of Apollo landing sites including Apollo 11, the dramatic Earthrise ; video and a mission ending live HDTV video broadcast of the spacecraft as it "Barn-Storms" over the lunar terrain during its voyage.

COSMO-SkyMed is an Earth-observation satellite space-based radar system funded by the Italian Ministry of Research and Ministry of Defence and conducted by the Italian Space Agency (ASI), intended for both military and civilian use. The prime contractor for the spacecraft was Thales Alenia Space. COSMO SkyMed is a constellation of four dual use Intelligence, surveillance, target acquisition, and reconnaissance (ISR) Earth observation satellites with a synthetic-aperture radar (SAR) as main payload, the result of the intuition of Giorgio Perrotta in the early nineties. The synthetic-aperture radar was developed starting in the late nineties with the SAR 2000 program funded by ASI.

The Canadian Advanced Nanospace eXperiment (CanX) program is a Canadian CubeSat nanosatellite program operated by the University of Toronto Institute for Aerospace Studies, Space Flight Laboratory (UTIAS/SFL). The program's objectives are to involve graduate students in the process of spaceflight development, and to provide low-cost access to space for scientific research and the testing of nanoscale devices. The CanX projects include CanX-1, CanX-2, the BRIght Target Explorer (BRITE), and CanX-4&5.

Horizons Satellite is a joint venture between Intelsat and SKY Perfect JSAT Group. Originally formed in 2001, pursuant to a memorandum of understanding between JSAT Corporation and PanAmSat for the launch of Horizons-1, it was renewed for Horizons-2. JSAT later merged into the SKY Perfect JSAT Group and PanAmSat was acquired by Intelsat, but the companies continued with the relationship, with the order for Horizons-3e. Both companies also launched a joint satellite, Intelsat 15/JCSAT-85, but instead of the equal share agreement of this joint venture, JSAT owns a specific payload of 5 transponders out of the 22 Ku band transponders of the spacecraft.

Operation Burnt Frost was a military operation to intercept and destroy non-functioning U.S. National Reconnaissance Office (NRO) satellite USA-193. The mission was described by the Missile Defense Agency as a "mission of safeguarding human life against the uncontrolled re-entry of a 5,000-pound satellite containing over 1,000 pounds of hazardous hydrazine propellant". The launch occurred on 21 February 2008 at approximately 10:26 p.m. EST from the USS Lake Erie, using a heavily modified Standard Missile-3 (SM-3) to shoot down the satellite. A few minutes after launch, the SM-3 intercepted its target and successfully completed its mission. The operation received scrutiny from other countries, mainly China and Russia.
