Category: Test unit for GBAS navigation system.
Test unit for GBAS navigation system, Thales ATM, Stuttgart
GBAS ground station is formed by reference receivers with their antennas installed in precisely surveyed points. The information generated in the receiver is sent to a processor that computes the corrections for each navigation satellite in view and broadcasts these differential corrections, besides integrity parameters and precision approach pathpoints data, via a Very High Frequency (VHF) Data Broacast (VDB).GBAS uses the concept of differential corrections to augment satellites signal in order to meet these requirements.
