Lockheed on scheduled with GPS III

Lockheed Martin has nearly finished with critical design review for the next-generation of the GPS satellite. Its team working on the GPS III satellite constellation was on schedule for the critical design review phase of the program. The team has finished 26 of the 65 CDRs for the program. Overall space vehicle CDR is scheduled for an August completion, two months ahead of schedule. GPS III scheduled for a 2014 launch, improves the network security, accuracy and reliability of the current constellation.

Boeing to provide Next-Generation GPS Ground Systems Support

Boeing will develop portions of the U.S. Air Force’s new ground control segment. It will provide infrastructure, development of the ground systems, and continued 24/7 operational and sustainment support for the current and future GPS satellite systems. It will install hardware and software at GPS control stations at Schriever Air Force Base in Colorado and Vandenberg Air Force Base in California.

Taoglas Antennas for Miniature Devices

Taoglas has launched the AP.35a, a 35 x 35-millimeter square GPS antenna for compromised environments where next-generation miniature tracking devices are placed, deep inside vehicles and assets. The AP.35a antenna is embedded securely in any GPS device, eliminating the need for an external antenna.

Indian GSL V-D3 Mission not successful

The flight-testing of the indigenous Cryogenic Engine and the Stage conducted in the Geosynchronous Satellite Launch Vehicle GSLV-D3 was not successful. GSLV-D3 vehicle performance was normal up to the end of the second stage (GS2) till 293 seconds. Afterwards, the Cryogenic Stage was to ignite and burn for about 720 seconds to provide the necessary velocity to inject GSAT-4 Satellite into the intended Geosynchronous Transfer Orbit. The vehicle was seen tumbling, lost altitude and finally splashed down in the sea. Detailed analysis of the flight data is being carried out to find out the exact reasons for the failure and take corrective measures to realise the next flight test of the indigenous Cryogenic Engine and Stage within the next one year.

Use GPS to control prices, suggests Indian PM’s core group

A meeting on rising prices in India, chaired by Prime Minister, Manmohan Singh, recommended the use of technology and GPS to track vehicles carrying essential commodities for better management of the public distribution system (PDS).

Russia to orbit 7 new GLONAS Satellites in 2010

“We are actively continuing to increase our space grouping. There are presently 23 satellites functioning in orbit, 21 of them operating perfectly, though the work the two remaining ones are under question,” according to Russian Prime Minister Vladimir Putin. He added that the additional seven satellites to be launched this year would bring the total to 27-28 fully functional satellites for the navigation system. He added that 2.5 billion rubles ($85.24 mln) was spent on the satellite system in 2009, and another 3.7 billion rubles was allocated for 2010-2011.

Portable GPS Jammers

Shoghi GPS Jammers transmit adequate power radio signals to cut-off communications between GPS Receiver and Satellite stations, by jamming the signals in the operating frequencies of GPS bands. It does not interfere with any communications other than GPS within the defined regulated zone. Upon activating the Jammer, all idle GPS receivers will indicate “NO SERVICE”. When the Jammer, is turned off, all GPS receivers will automatically re-establish communications and provide full service.

India to have GPS based navigation system by next year

India would have a GPS-based aviation navigation system by next year, Civil Aviation Minister Praful Patel has said. “In the meantime we would be doing trial run on borrowed satellite. This is for the entire Indian network. Our entire air mapping would be done by GPS,” he said, adding that India is moving into GPS satellite based navigation system from the present ground based navigation system.

Bill promotes GPS in air traffic system

The transformation of the US’s air traffic system by replacing World War II-era radars with 21st century GPS technology would be accelerated under a bill approved by the Senate. The USD 34.5 billion bill funds the Federal Aviation Administration (FAA) through Sept. 30, 2011. The centre-piece of the bill calls for key elements of the FAA’s NextGen programme to be in place at the busiest American airports by 2014. The system is crucial to handling the expected growth in air traffic from about 700 million passengers in 2009 to the more than 1 billion annually by 2023.

OGC: Aviation Domain Working Group

The Open Geospatial Consortium (OGC) announced the formation of an Aviation Domain Working Group (DWG). It will support the evaluation, advancement, operational use and validation of OGC standards within the aviation domain. It will contribute towards increasing global adoption of OGC standards and complementary standards and coordinate the technical input, when required, to support profiling or extending those standards to meet the requirements of the aviation community.
