Electronic Engineering Information 2009 3 Figure 6GAGAN system diagram (tSRO) is the U.S. Federal Aviation Administration (FAA) to help develop the navigation system. GAGAN system is planned to launch ISRO's geostationary orbit satellites help expand the amount of GPS data. AAI is responsible for building the ground infrastructure, including base stations, uplink earth station and control center. GAGAN project costs 7.74 billion rupees, which invest 5.96 billion rupees AAI, ISRO invest l7.8 billion rupees. The first phase has cost $ l4.8 billion rupees. Previously, Raytheon has been involved in the development of GAGAN system in August, the company announced during the year to India, ISRO will submit solutions, and to assess the past few years the development of technology demonstration system phase of GAGAN experience gained improved. 2. The continuous development of inertial navigation systems. To a large number of troops inertial navigation system (INS) is not dependent on any external information, not to the external radiation energy of autonomous navigation system, with good concealment, in the air,GHD gl?tteisen günstig, ground, surface and underwater work. In 2008, the inertial navigation system to order and development activities are still relatively active, a subsidiary of Northrop Grumman Sperry Marine Branch in the field of technical leading position. In August, a subsidiary of Northrop Grumman Sperry Marine Branch received a contract for two new Royal Australian Navy amphibious assault ships to provide an integrated navigation system. The navigation system includes two sets of branches produced by the Sperry Marine MK39Mod3A type of ring laser gyro navigator (RLGN) inertial navigation system. Sperry Marine Branch through the use of NavDDS data distributed network, RLGN will work with the ship's radar, electronic drawing system, autopilot, steering control, speed and depth sensors, GPS and DGPS positioning system, automatic identification system, navigation data loggers, and other systems and sensors integration. Subsequently, the Sperry Marine Branch was awarded a new offshore patrol for the Spanish Navy ship high-precision inertial navigation system contract, these navigation systems company in Navan Tia Ferrol shipyard production. The contract is worth more than $ 1.5 million. Each ship will be equipped with a set of offshore patrol vessels MK39Mod3A type of ring laser gyro inertial navigation system and a MK27-type sea fiber optic gyrocompass. Sperry Marine business unit has the same time the Spanish navy surface ships and submarines to provide the navigation system,ed hardy bikini, the current MK39Mod3A type of ring laser gyro inertial navigation system has equipment in 32 countries on naval vessels. 3. Navigation system has broad prospects, favored by the national army is a different combination of navigation in accordance with a certain way navigation technology combined with appropriate, to achieve a variety of navigation information under the complementary advantages,abercrombie deutschland, thereby enhancing the overall navigation performance. The most common form of navigation is inertial navigation and GPS satellite navigation combination. In 2008, the world's navigation system is also equipped with a certain development. In February, the Indian aircraft maker Hindustan airlines from the security company Sagem Defense ordered more than 100 sets of SIGMA95N navigation system. These systems will be used in the Indian light combat aircraft project in the Indian Air Force Sukhoi fighters and the Tejas fighter aircraft company. Sukhoi's 30 series aircraft, MiG-27, MiG-27s, Jaguars and India, By Sagem Defense Security, developed and manufactured SIGMA95A system is a standalone inertial laser gyro navigation system with integrated GPS / GLONASS system. The system for combat aircraft to provide precision navigation and adaptation of high-intensity operations. Wells rose and Raytheon received $ 39 million to upgrade Taiwan's Patriot radar, according to fixed-price contract (letter amendment to the contract) for the procurement, installation and testing of radar to enhance Taiwan's three Patriot stage Ⅲ / classification, recognition and identification of stage Ⅲ upgrade accessories. Andover, MA Province, this work is being carried out, all the work is estimated to go to May 31, 2015 to complete. Tender has been issued and tenders received. U.S. Army Aviation and Missile Command, Contract Center, the Army Contract Command, Redstone Arsenal took part in the bidding (W31P4Q-07 a C-0151). (Xue Shunyong translation)
