卫星导航系统的服务完好性空间信号精度(signal in space accuracy,SISA)参数由广播星历中播发的完好性索引指数通过相应的转换算法计算得到,用于星历空间测距误差及定位服务精度的预测。基于实测数据,评估了北斗三号全球导航卫星系统(BeiDou navigation satellite system-3,BDS-3)完好性SISA参数对空间测距误差的包络能力。结果表明完好性SISA
oc
参数对轨道径向与钟差的综合测距误差存在漏包络现象。为了解决这一问题,基于395 d历史数据,提出一种改进的SISA参数索引转换算法,该算法包括SISA
ocb
取值优化和SISA
oc1
算法优化两部分。在SISA
ocb
取值优化中,取历史所有卫星轨道径向误差与钟差误差均方根值之和的最大数作为SISA
ocb
的最小限值。在SISA
oc1
算法优化中,通过钟差拟合提取的一次项系数最值与自变量自由取值公式计算的SISA
oc1
相比,确定SISA
oc1
参数计算公式中的常数
N
值。通过对8个月的实测数据进行分析,验证了所提算法的优势,实现了SISA
oc
参数对卫星沿径向误差的零次漏包络(不包含卫星在境外时广播星历显著异常情况),降低了因电文参数播发值不合理带来的BDS-3系统完好性参数漏包络事件。
Objectives
2
To improve the leakage envelope phenomenon of BeiDou navigation satellite system-3 (BDS-3) signal in space accuracy (SISA) integrity parameter to the comprehensive ranging errors induced by the orbit radial and clock errors
an improved SISA parameter index conversion algorithm based on 395 d of historical data is proposed.
Methods
2
The algorithm consists of two parts: SISA
ocb
(SISA parameter associated with orbit radial and clock accuracy) and SISA
oc1
(SISA parameter associated with satellite clock speed accuracy) algorithm optimization. In SISA
ocb
value optimization
the root mean square maximum of orbit radial and clock comprehensive error of all satellites in history is taken as the minimum limit of SISA
ocb
. In the optimization of SISA
oc1
algorithm
the maximum of first-order coefficient extracted through clock error fitting is compared with SISA
oc1
ca
lculated by free value formula of independent variable to determine the constant
N
in the SISA
oc1
parameters calculation formula.
Results
2
By analyzing measured data of 8 months
the advantages of the proposed algorithm are verified. The new algorithm can achieve the zero leakage envelope of SISA
oc
parameters for satellite radial and clock errors (excluding significant anomalies in broadcast ephemeris for satellite abroad)
and reduce the leakage envelope event of BDS-3 integrity parameter caused by unreasonable SISA broadcast values.
Conclusions
2
The effective optimization algorithm and analysis results for BDS-3 SISA
oc
parameters can provide a valuable reference for the upgrading and construction of BDS-3 system integrity service.
