Raytheon completed preliminary test for GAGAN

Raytheon Company, UK successfully completed the Preliminary System Acceptance Test for the GPS Aided GEO Augmented Navigation- Technology Demonstration System (GAGAN-TDS). “This test was significant because the GAGAN-TDS ground elements supplied by Raytheon were installed and integrated ahead of schedule,” said Andy Zogg, Vice President of Raytheon’s Airspace Management and Homeland Security Business. “More importantly, the system functioned properly and exceeded the accuracy requirements.

The GAGAN-TDS network monitors the Global Positioning Satellite signals for errors and then generates correction messages to improve the accuracy of endusers’ position solution.

During the test period, average accuracy was better than one meter (3.3 feet) horizontally and only slightly more than one meter vertically, thus surpassing the 7.6 meter (25 feet) requirement by a significant margin. GAGAN-TDS is the first phase of a project sponsored by the Indian Space Research Organization (ISRO) and Airports Authority of India (AAI) to implement a space-based navigation system in Indian airspace.

Lockheed Martin completes fifth modernized GPS satellite

Lockheed Martin has completed the fifth in a series of eight modernized GPS IIR satellites that the company is developing for the US Air Force. The spacecraft are the most technologically advanced GPS satellites ever developed and will provide significantly improved navigation performance for US military and civilian users worldwide.

In India

The child tracking device, based on the GPS, is developed by the Indian Institute of Science (IISc), Banhalore. It is going to be the size of a sleek mobile phone, costing eventually about Rs 5000, and can be fitted into the child’s shoe, belt or worn like a wristwatch. Information from this device is periodically transferred to the General Packet Radio Service (GPRS) linked to a central server.

• The Indore City Transport Services Limited, India is running a fleet of ultra-modern buses equipped with GPS, which helps in regulating their movement, especially in maintaining the crucial time factor.

• GPS is being introduced in trains on three sections under a pilot project, government told the Lok Sabha, India. The project Satellite Imaging for Rail Navigation (SIMRAN) is to be completed by March 2008 and will incur a cost of Rs 2 crores, Minister of State for Railways R Velu said in a written reply. The project is being carried out jointly by Research Designs and Standards Organization (RDSO), Lucknow, and Indian Institute of Technology (IIT), Kanpur.

• A fleet of 30 Taveras fitted with GPS will keep a check on fatal accidents on the 23-km long, eight-lane Noida-Greater Noida Expressway in the next few days in India. The 30 vehicles to be fitted with GPS include fire tenders, ambulances, and vehicles involved in supplying water and removing carcasses of animals from roads. Besides these, 5-6 police vehicles would be deployed for patrolling.
