Embodiment Construction

[0028] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] The present invention provides a near-real-time inspection service system for BDS satellite orbit based on SLR, which is composed of three subsystems: (1) Linux server end realizes SLR daily inspection process; (2) compiles SLR residual data set and summary report (3) Realize the visual analysis of SLR residual error, and describe each component of the system in detail below:

[0030] (1) The Linux server side implements the SLR daily inspection process, such as figure 1 As shown, the subsystem is implemented through the following three steps:

[0031] Step 1: Collect and organize the required data sets for SLR verification

[0032] The collected and organized data sets include: SLR standard point format (NPs) data provided by EDC (European Data Center); BDS multi-source, heterogeneous satellite orbit products of multiple Beidou / GNSS an...

Abstract

The invention provides an SLR-based BDS satellite orbit near-real-time check service system, which solves the technical problems that the existing BDS multi-source heterogeneous satellite orbit product check strategy is tedious and the system construction is complex, and is composed of three subsystems: realizing an SLR daily check process by a Linux server side; compiling an SLR residual data setand a summary report; realizing visual analysis of the SLR residual error; the system can be widely applied to the field of satellite orbit dynamics application.

Description

technical field [0001] The invention relates to the application field of satellite orbit dynamics, in particular to an SLR-based BDS satellite orbit near real-time verification service system. Background technique [0002] Since 2012, my country's Beidou navigation satellite system (BDS) has begun to develop rapidly, especially in the past two years, and my country's BDS-3 system will realize full constellation operation, and there will be more than 50 BDS multi-source and heterogeneous The satellites operate in real time, including BDS-2 and BDS-3 satellites, and their respective medium earth orbit (MEO), inclined geosynchronous orbit (IGSO) and geostationary orbit (GEO) satellites. The global BDS multi-source, heterogeneous satellites will It will become more and more important in our future life, especially in the basic data support of satellite positioning and navigation. Among them, the accuracy of satellite orbit products is very important. All BDS satellites are equippe...
