Introduction

The BeiDou satellite navigation system is divided into three stages of construction and development. BeiDou-1, BeiDou-2 and BeiDou-3. The public signals of positioning, navigation and timing services broadcast before include B1I, B2I, B3I, B1C, B2a and B2b. Among them, B1I and B3I signals are in Beidou Medium Earth Orbit (MEO) satellites, Inclined Geosynchronous Orbit (IGSO) satellites and Geostationary Orbit (GEO) satellites of BeiDou-2 and BeiDou-3 The B2I signal is broadcast on all BeiDou-2 satellites and will be replaced by the B2a signal on BeiDou-3 satellites. The B2b signal is broadcast on BeiDou-3 medium earth orbit (MEO) satellites and inclined geosynchronous orbit (IGSO) satellites. The B2b signal is a downlink satellite navigation signal broadcast by the BeiDou-3 satellite (GEO/IGSO/MEO), which includes the I branch and the Q branch. It also carries services such as positioning, navigation and timing, global short message communication reverse link, and international search and rescue reverse link. It consists of five parts. --Part 1.Public Service Signal B1C. The purpose is to establish the public service signal B1C between the space constellation and the user terminal. signal characteristics, navigation message structure and user algorithms, etc. --Part 2.Public Service Signal B2a. The purpose is to establish the public service signal B2a between the space constellation and the user terminal. Signal characteristics, navigation message structure and user algorithms, etc. --Part 3.Public Service Signal B1I. The purpose is to establish the public service signal B1I between the space constellation and the user terminal. Signal characteristics, navigation message structure and user algorithms, etc. --Part 4.Public Service Signal B3I. The purpose is to establish the public service signal B3I between the space constellation and the user terminal. Signal characteristics, navigation message structure and user algorithms, etc. --Part 5.Public Service Signal B2b. The purpose is to establish the public service signal B2b between the space constellation and the user terminal. Signal characteristics, navigation message structure and user algorithms, etc. BeiDou Navigation Satellite System Space Signal Interface Specification Part 5.Public Service Signals B2b

1 Scope

This document specifies the public communication between the BeiDou Navigation Satellite System (hereinafter referred to as the BeiDou System) space constellation (IGSO/MEO) and user terminals. The signal characteristics, navigation message structure and user algorithm of the service signal B2b are opened. This document applies to the development, production and inspection of products that use B2b signals to achieve positioning, navigation and timing.
