Introduction

At present, my country's Beidou satellite navigation system has been widely used in the fields of surveying and mapping, exploration, marine transportation and fishing, vehicle positioning and monitoring. Whether it is professional users or public users, there is a corresponding demand for Beidou precision service products, but so far there is still a lack of Beidou precision service products. Related standards for products. Therefore, it is urgent to formulate the precision service product standard of Beidou satellite navigation system. This standard aims to formulate relevant standards for my country's Beidou precision service products (such as precision orbits, precision clock offsets, ionosphere, etc.) Fans the use of Beidou precision service products in my country, realizes the standardized output of Beidou precision service products, and accelerates the development of Beidou precision service products in all walks of life And global promotion and application. Beidou Precision Service Product Specification

1 Scope

This standard specifies the types and file content, naming rules, file formats and verification methods of Beidou satellite navigation system precision service products. This standard applies to the production and application of Beidou satellite navigation system high-precision positioning, speed measurement, timing, attitude measurement and other data service products.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this document. For undated references, the latest version (including all amendments) applies to this document. GB/T 17159-2009 Geodetic terminology

3 Terms and definitions

The following terms and definitions defined in GB/T 17159-2009 apply to this document. 3.1 Satellite precision orbit The processed satellite high-precision orbit data. 3.2 Satellite precision clock Satellite high-precision clock data obtained by processing accurate estimation or extrapolation. 3.3 Ionospheric delay When the navigation signal passes through the ionosphere, the transmission delay is relative to the signal propagation in vacuum. 3.4 Code deviation The difference in device delay when different ranging code signals are transmitted in the same device. 3.5 Device delay decimal deviation The non-integer part of the equipment delay of the carrier phase of the navigation satellite signal. 3.6 Tropospheric delay When the radio signal passes through the troposphere in the earth's atmosphere, it is affected by atmospheric refraction, resulting in time delay and path curvature, resulting in signal propagation delay. 3.7 Earth rotation parameters Indicates the speed of the earth's rotation, the direction of the rotation axis and the parameters of its change.
