ADS-B data observation and processing in ASEAN

At present ADS-B is considered as an additional standard for tracking aircraft. There need to check quality of ADS-B system for example precision of positioning and speed. The amount of error tolerance of each flight range can very different. That why there a need to collect the quality of ADS-B data in each area. Therefore, we using software defined radio (SDR) to receive ADS-B and Mode-S messages and compute it using the software program that we created to use in Raspberry Pi. The program will compute the ADS-B and Mode-S messages.

ADS-B Data

Displays information of ADS-B messages that are received from aircraft in a single message.This message show multiple variables such as speed, altitude, NACp, NIC SIL, etc.
