Introduction
The Beidou Satellite-Based Augmentation System (BDSBAS) is an important part of the Beidou system, through BDSBAS-B1C and BDSBAS-
B2a enhances the signal and provides users in China and surrounding areas with single-frequency enhanced services and dual-frequency services that comply with the requirements of the International Civil Aviation Organization (ICAO) standards.
Multi-constellation enhanced services.
This document defines the relevant content of the Beidou Satellite-based Augmentation System single-frequency augmentation service signal BDSBAS-B1C. It is a reference for Chinese satellite navigation
Technical document "Beidou Satellite Navigation System Space Signal Interface Control Document Satellite-based Enhanced Service Signal" issued by the System Management Office
Standard conversion carried out by BDSBAS-B1C (version 1.0).
The Beidou satellite-based augmentation system space signal interface specification is planned to consist of two parts.
---Part 1.Single frequency enhanced service signal BDSBAS-B1C;
---Part 2.Dual-band enhanced service signal BDSBAS-B2a.

GB/T 39267-2020 Beidou Satellite Navigation Terminology
3 Terms, definitions and abbreviations
3.1 Terms and definitions
The terms and definitions defined in GB/T 39267-2020 and the following apply to this document.
3.1.1
Navigation satellites operating in geostationary orbit (GEO).
Note. GEO is a prograde orbit in which the inclination and eccentricity of the satellite orbit are zero, and the operating period is the same as the earth's rotation period (about 24 hours).
[Source. GB/T 39267-2020,3.2.4]
3.1.2
GPS time GPStime; GPST
The time base established and maintained by GPS uses SI seconds for continuous time without leap seconds. The starting epoch of GPST is UTC
At 00.00.00 on January 6, 1980, traced to UTC (USNO).
Note. GPST uses week counts and seconds within the week.
[Source. GB/T 39267-2020,2.2.17]
3.1.3
WGS-84 Geodetic Coordinate SystemWorldGeodeticSystem-84
The geodetic coordinate system used by GPS. The origin of its coordinate system is located at the center of mass of the earth, and the Z-axis points to the (International Time Bureau) BIH1984.0
The defined direction of the Protocol Earth Pole (CTP), the X-axis points to the intersection of the zero-degree meridian of BIH1984.0 and the CTP equator, and the Y-axis satisfies the right-hand
law.
