Introduction to BeiDou-3 Navigation Satellite System

State Key Laboratory of Geo-Information Engineering, Xi’an,China

ABSTRACT: China BeiDou navigation system (BDS) has experienced demonstration navigation satellite system (BDS-1) and regional navigation satellite system (BDS-2). The global BeiDou navigation system (BDS-3) is in construction and goes well. The design and functions of BDS-3 are quite different from those of BDS-1 and BDS-2. The general constituent frame of BDS-3 and its coordinate reference system and system time are introduced. The new payloads mounted on different satellites for different objectives are elaborated. The general service contents and special service functions provided by different constellations are described. The initial performances of the simplest system of BDS-3 are evaluated based on the available 8 MEO satellites of BDS-3. The performances of satellite orbit determination and prediction with and without the inter-satellite links (ISL) are compared and analyzed.
