摘要: 北斗导航卫星发射场系统GNSS控制网是为北斗卫星发射提供高精度的位置基准、射向基准及轨道测控基准,本文针对发射场系统GNSS控制网建立技术特点,以控制网观测的效率性、可靠性、经济性、精度性为优化设计指标,分别从控制基准优化选取、网形结构设计以及优化精度估算等方面对实施方案进行了优化设计,并通过实际作业验证该优化设计方法的科学性和可操作性。Abstract: 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.
