Introduction

Beidou airborne equipment for aviation-aided navigation is based on the use of Beidou satellite navigation system by civil aviation industry users in transport aircraft and general aviation aircraft.

It is an airborne dedicated terminal used by the target aircraft in the en-route phase to meet the actual application needs of the B1C frequency point for auxiliary navigation.

The BeiDou airborne equipment specified in this document is expected to provide position/velocity/time (PVT) information to other airborne terminal equipment.

A failure that causes erroneous information is a minor failure state, and a loss of function is a failure state with no safety impact.

Beidou airborne navigation equipment refers to the relevant technical standards of China's civil aviation. Generally, Beidou airborne equipment is divided into two types.

Beta equipment and Gamma equipment, of which Beta equipment consists of independent Beidou airborne equipment, which is expected to be other terminal The terminal device provides information such as position/speed/time (PVT). The error information caused by the failure of Beta devices is a minor failure.

Gamma equipment consists of Beidou airborne equipment and display and control devices, and has route guidance For devices with navigation and display functions, there is no standard minimum failure state category for Gamma devices. Record its functions when designing the device.

Failure condition categories of loss and malfunction.

In order to maintain the compliance of BeiDou airborne equipment with relevant civil aviation standards, the functions of BeiDou airborne equipment in this document are as follows.

The energy and performance requirements are consistent with Beta equipment and are suitable for use on civil aircraft.
