Abstract

The invention provides an ARAIM ground monitoring station integrity monitoring method and an ARAIM ground monitoring station integrity monitoring device. The ARAIM ground monitoring station integrity monitoring method provided by the invention comprises the following steps: acquiring first user range accuracy URA and second user range accuracy URA, wherein the first user range accuracy URA is the user range accuracy URA in a current preset period of time, and the second user range accuracy URA is the user range accuracy URA in a future preset period of time; determining an adopted advanced receiver autonomous integrity monitoring ARAIM structure according to the first user range accuracy URA, the second user range accuracy URA and a preset user range accuracy URA threshold, wherein the ARAIM structure is an online or offline structure; and performing ARAIM ground monitoring station integrity monitoring according to the ARAIM structure. The ARAIM ground monitoring station integrity monitoring method and the ARAIM ground monitoring station integrity monitoring device provided by the invention can meet the requirement of most areas for accuracy and integrity. The application rang is expanded, and the usability of LPV-200 is improved.

Description

technical field [0001] The present invention relates to navigation technology, in particular to a method and device for monitoring the integrity of an Advanced Receiver Autonomous Integrity Monitoring (Advanced Receiver Autonomous Integrity Monitoring; ARAIM) ground monitoring station. Background technique [0002] The Global Navigation Satellite System (GNSS for short) has become an important space infrastructure with its global, all-weather, continuous and high-precision characteristics. At present, it has been widely used in land, ocean, aerospace and other fields. ARAIM can realize the enhancement of GNSS. On the one hand, ARAIM guarantees the positioning accuracy, and on the other hand, it realizes the monitoring of the working status of satellites. It is an independent and effective method for the integrity monitoring of satellite positioning. ARAIM supports horizontal navigation and vertical navigation, and can meet the precision approach based on horizontal and ver...
