Ground Based Augmentation Systems (GBAS)

The main activity of EUROCAE WG-28 for the past years has been on standards for Ground Based Augmentation Systems (GBAS). The major achievements were the revision A of ED-114 (“MOPS for Global Navigation Satellite GBAS Ground Equipment to support Category I Operations”) published in 2013 and the recent publication of Change 1 to ED-114A that results from a maintenance work to correct issues that have been detected during various GBAS CAT-I implementation programs.
