ЦитироватьЦитироватьI spied a LM-3A rocket complete with fairings printed with the Compass system program logo in Xichang... Hmm this is becoming more and more interesting: in this article the project manager of the Compass navigation system says that there will only be one more launch for the program this year in December (from the hints from the post above, that would most probably be the Compass-IGSO-5 launch by a LM-3A), with 6 more satellites going up in 2012. Now where do I find 12 more satellites and 7 more rockets that will go up this year?

ЦитироватьChina breaks record with Long March 3A launch of another BeiDou-2 satellite[/size]December 1st, 2011 by Rui C. BarbosaA record breaking 16th successful launch of the year for China took place at 21:07 UTC on Thursday, when a Long March 3A (Chang Zheng-3A) launch vehicle orbited a new navigation satellite – another for the BeiDou-2 Compass satellite navigation range – from the Xichang Satellite Launch Center, in Sichuan Province.China's Record:This launch was the 16th successful orbital launch this year for China, breaking the previous launch record of 15 successful missions in 2010. Taking into account the launch failure on August 18th, this was the 17th space launch for China this year.The satellite that was orbited is the fifth BeiDou-2 IGSO (Inclined GSO) satellite of the system. The satellites were developed in the basis of the DFH-3B satellite platform and have a lifespan of eight years.This constellation of Compass satellites will consist of 35 vehicles, including 30 MEO (21,500 km orbits) and IGSO (inclined at 55 degrees) satellites and five GSO satellites.The Compass Navigation Satellite System (CNSS) is China's second-generation satellite navigation system approved by the Chinese government in 2004, and is capable of providing continuous, real-time passive 3D geo-spatial positioning and speed measurement.The system was initially used to provide high-accuracy positioning services for users in China and its neighboring regions, covering an area of about 120 degrees longitude in the Northern Hemisphere. The long-term goal is to develop a global navigation satellite network similar to the GPS and GLONASS by 2020.The system will have two kinds of services: a civilian service that will give an accuracy of 10 meters in the user position, 0.2 m/s on the user velocity and 50 nanoseconds in time accuracy; and the military and authorized user's service, providing higher accuracies. The first phase of the project will see the coverage of the Chinese territory but in the future the Compass constellation will cover the entire globe.The satellites transmit signals on the: 1195.14-1219.14MHz, 1256.52-1280.52MHz, 1559.05-1563.15MHz and 1587.69-1591.79MHz, carrier frequencies.The previous BeiDou-2 'Compass' launch took place on July 26 when a Chang Zheng-3A orbited the 'Compass-I42 (37763 2011-038A) satellite.This was the 22nd flight of the CZ-3A Chang Zheng-3A launch vehicle. The CZ-3A is a three-stage liquid launch vehicle, which has inherited the mature technology of the CZ-3 Chang Zheng-3. An upgraded liquid hydrogen and liquid oxygen cryogenic third stage has been developed to enable CZ-3A performing greater geostationary transfer orbit (GTO) capability.The CZ-3A is equipped with a more flexible and sophisticated control system which supports substantial attitude adjustments to orient the payloads before spacecraft separation and provides adjustable satellite spin-up rotation rate. It has paved the way for the development of CZ-3B Chang Zheng-3B and CZ-3C Chang Zheng-3C, and become the basic type of GTO launch vehicles.The CZ-3A is mainly used for GTO missions; it also can be used for LEO, SSO and polar orbit missions, as well as dual-launch and multiple-launch missions. The launch capacity of the CZ-3A to GTO is 2,650 kg, the lift-off mass is 241,000 kg, the overall length is 52.5 meters, the diameter of first stage and second stage is 3.35 meters, the diameter of third stage is 3.0 meters, and the maximum fairing diameter is 3.35 meters.The first stage and second stage of CZ-3A employ storable propellants, i.e. unsymmetrical dimethy1 hydrazine (UDMH) and nitrogen tetroxide (N2O4), and the third stage uses cryogenic propellants, i.e. liquid hydrogen (LH2) and liquid oxygen (LOX).On the first stage the CZ-3A uses a DaFY6-2 engine with 2961.6 kN of thrust, while the second stage is equipped with a DaFY20-1 main engine (742 kN) and four DaFY21-1 vernier engines (11.8 kN each). The third stage is equipped with two YF-75 engines (78.5 kN each).The fairing diameter of the CZ-3A is 3.35 meters and has a length of 8.89 meters.CZ-3A consists of rocket structure, propulsion system, control system, telemetry system, tracking and safely system, coast phase propellant management and attitude control system, cryogenic propellant utilization system, separation system and auxiliary system, etc.The launch success rate of CZ-3A is 100 percent since its maiden flight on February 8, 1994 when it successfully launched two experimental satellites (the Shi Jian-4 and the Kua Fu-1, a DFH-3 model). And it was awarded the "Gold Launch Vehicle" title by China Aerospace Science and Technology Corporation in June 2007.This was the 153rd successful Chinese orbital launch, the 153rd launch of a Chang Zheng launch vehicle, the 8th launch from Xichang in 2011 and the 67th orbital launch from Xichang.The Xichang Satellite Launch Centre is situated in the Sichuan Province, south-western China and is the country's launch site for geosynchronous orbital launches.Equipped with two launch pads (LC2 and LC3), the centre has a dedicated railway and highway lead directly to the launch site. The Command and Control Centre is located seven kilometers south-west of the launch pad, providing flight and safety control during launch rehearsal and launch.Down range Tracking and Control stations of the launch center are located in Xichang City and Yibin City of Sichuan Province, and Guiyang City of Guizhou Province. Each of them houses tracking and measurement equipment for the powered phase of a launch vehicle flight.Other facilities on the Xichang Satellite Launch Centre are the Launch Control Centre, propellant fueling systems, communications systems for launch command, telephone and data communications for users, and support equipment for meteorological monitoring and forecasting.During 1993-1994 Xichang underwent extensive modernization and expansion, in part due to the requirements of the CZ-3 launcher family and in part to meet commercial customer needs.The first launch from Xichang took place at 12:25UTC on January 29, 1984, when the CZ-3 Chang Zheng-3 (CZ3-1) was launched the Shiyan Weixing (14670 1984-008A) communications satellite into orbit.Before the end of the year China plans two more launches. The launch of the NigComSat-1R communications satellite for Nigeria is schedule to take place on December 19. Launched by a CZ-3B/E Chang Zheng-3B/E rocket from Xichang, this satellite will replace the NigComSat-1 satellite that lost power from the southern solar array and latter failed in November 2008 due to a technical error of the satellite's northern solar array.The other launch schedule for December will orbit the ZiYuan-1 (2C) Earth resource satellite using a Chang Zheng-4B launch vehicle from Taiyuan.[/size]
ЦитироватьСичан, 2 декабря /Синьхуа/ -- Сегодня в 05:07 с космодрома Сичан /провинция Сычуань, Юго-Западный Китай/ с помощью ракеты-носителя "Чанчжэн-3" /"Великий поход-3"/ произведен успешный запуск 10-го со счету навигационного спутника серии "Бэйдоу", который вскоре был выведен на намеченную орбиту. Это пятый по счету спутник, находящийся на наклонной геостационарной орбите и входящий в навигационную систему "Бэйдоу".В Китае в основном завершено строительство данной региональной системы и в данный момент идет ее тестирование и оценка. Ожидается, что к концу года система начнет в пробном порядке предоставлять находящимся в Китае и соседних с ним государствах клиентам услуги по позиционированию, навигации и показанию времени и тем самым удовлетворять потребности таких отраслей, как транспорт, рыбное хозяйство, лесное хозяйство, метеослужбы, коммуникационная связь, водное хозяйство и так далее, а также потребности обычных пользователей.Согласно стратегии развития "в три этапа" до конца 2012 года Китай запустит еще какое-то количество спутников навигации, которые пополнят данную навигационную систему и позволят увеличить количество функций обслуживания, расширить сферу охвата системы и завершить создание региональной спутниковой системы навигации. Примерно к 2020 году Китай готов будет закончить формирование глобальной спутниковой навигационной системы "Бэйдоу", состоящей из 30 с лишним спутников и способной предоставлять надежные навигационные услуги в глобальном масштабе.
