Embodiment 1

[0049] In this embodiment, for the existing ADS-B messages are sent back to the ground through the digital transmission channel, only a small amount of load telemetry data can be downloaded in real time through telemetry, so that the satellite lacks real-time information on the ADS-B on-board load processing capability. The problem of monitoring provides a monitoring method for spaceborne ADS-B messages. Through the satellite telemetry channel, the overall message resolution capability and accuracy of the ADS-B load can be monitored intuitively in real time, so as to realize the monitoring of the spaceborne ADS-B load. Real-time monitoring of functions. The method as figure 1 shown, including:

[0050] S1: According to the ADS-B message format, pre-establish a first message table and a second message table in the data storage module of the spaceborne ADS-B payload system, and establish the first message table and the second message table An index file of the key fields of th...

Embodiment 2

[0086] This embodiment provides a monitoring device for an on-board ADS-B message, such as Figure 4 As shown, the device includes:

[0087] Message table building module 1, according to ADS-B message format, set up the first message table, the second message table, and set up the index file of the key field of the first message table and the second message table, the first message table The key fields of the first message table and the second message table include at least the ICAO number;

[0088] The message acquisition module 2 writes the messages obtained by the ADS-B message solving algorithm into the first message table in real time according to the time sequence of completing the solving;

[0089] Message transmission module 3, according to the ICAO number of index file, randomly reads several messages in the first message table, and writes into the second message table after putting a time stamp on each message; The table cyclically outputs a preset number of messag...

Abstract

The present invention discloses a monitoring method, device and storage medium for satellite-borne ADS-B messages. Aiming at the existing ADS-B messages being sent back to the ground through a digital transmission channel, only a small amount of load telemetry data can be telemetry. Real-time downloading makes the satellite lack real-time monitoring of the ADS-B on-board load processing capability. Through the satellite telemetry channel, multiple pieces of ADS-B message data that have been solved are randomly transmitted per second, and it is ensured that there is no problem within the predetermined time. It will output messages with the same ICAO number, and can monitor the overall message calculation capability and accuracy of the ADS-B payload in real time and intuitively while not occupying too much satellite telemetry resources, and realize the control of the satellite-borne ADS-B payload function. real-time monitoring.

Description

technical field [0001] The invention belongs to the design field of spaceborne ADS-B loads, and in particular relates to a monitoring method, device and storage medium of spaceborne ADS-B messages. Background technique [0002] ADS-B is an aircraft operation monitoring system based on GPS satellite positioning and air-ground, air-air data communication. The ADS-B system can provide real-time and accurate aircraft identity information and four-dimensional position information. It is a new generation of air traffic control surveillance technology suitable for civil aviation and general aviation. The International Civil Aviation Organization (ICAO) identified it as the mainstream technology for future surface and aerial surveillance systems, and after the Malaysia Airlines crash in 2014, it was mandatory for global civil aviation airliners to install the ADS-B system. [0003] The space-borne ADS-B payload developed on this basis can receive wide-area ADS-B signals from satell...
