Introduction
Analysis of the core content of the standard
| Product type | Update cycle | Accuracy index | Typical application |
|---|---|---|---|
| Satellite precision orbit | 15 minutes sampling | 2-8mm | Surveying and mapping, earthquake monitoring |
| Ionospheric delay | 2 hours sampling | 0.1TECU | Communication delay correction |
Technology evolution and standard background
This standard fills the gap in the standard of high-precision service products of the BeiDou system in my country, and for the first time systematically standardizes the technical elements of 8 types of products such as precision orbit and clock error. Compared with the SP3-c format of GPS, it innovatively adds the device delay decimal deviation parameter unique to BDS.
Analysis of key parameters
Implementation Suggestions
- For precise positioning applications, it is recommended to give priority to the final product (10-day delay)
- For real-time dynamic applications, the ultra-fast product forecast part can be used
- For ionospheric modeling, attention should be paid to the 2-hour time resolution
