Design and Precision Analysis of the GNSS Control Network of the BeiDou Satellite Launch Site

 GNSS control network of the launch site of BeiDou navigation satellites is used to provide high precision position reference, high direction reference and high orbit control reference, and is the key to ensure the satellite launch vehicle successfully launched and precisely orbited. design of the measurement and control network should be scientific and precise, and take outside practice feasibility. This article discussed on technical design and measurements implement of GNSS control network, estimated the GNSS accuracy of control network by measurement working, and verified the technology design’s feasibility of Beidou satellite launch site GNSS control network.
