Introduction
Beidou Satellite Based Augmentation System (BDSBAS) provides single-frequency enhancement services and dual-frequency multi-constellation enhancement services. The service signals pass through Beidou satellites.
Navigation System (BDS) broadcast from geostationary orbit (GEO) satellites.
The enhancement object of the BDSBAS single-frequency enhancement service is the GPSL1C/A frequency point, which meets the requirements for precise flight stages such as route, terminal area and approach.
Indicator requirements for accuracy, integrity, continuity and availability. Within the BDSBAS single-frequency enhanced service area, the service level is determined by the system service capability
Determined jointly with onboard equipment.
BDSBAS airborne equipment is used to implement route, terminal area, lateral navigation (LNAV) and positioning performance (LP) approaches without vertical guidance.
It provides horizontal navigation for moving aircraft and implements Positioning Performance with Vertical Guidance (LPV) and Lateral Navigation/Vertical Navigation (LNAV/
VNAV) aircraft approach flight provides horizontal and vertical navigation. When the aircraft is outside the BDSBAS single-frequency enhanced service area, the aircraft
Onboard equipment needs to adopt fault detection and isolation (FDE) mode to ensure integrity.
In order to maintain the compliance of BDSBAS airborne equipment with international standards, this document contains information on the composition and categories of BDSBAS airborne equipment.
The model, constraints, general requirements and equipment performance requirements under different flight modes are consistent with RTCADO-229F.
