Because LabSat records all RF data that is present in the original signal, any satellite based augmentation system (SBAS) on the same frequency (1575.42Mhz) such as WAAS, EGNOS or MSAS, is automatically recorded and replayed.
Screenshot taken during a replay showing 18 satellites being tracked
On the right is a screenshot showing the status of a GPS engine under test. We recorded a 5 minute scenario and then replayed the data into the RF connector on the GPS engine. As you can see it tracked 14 GPS satellites, 1 Gallileo satellite and three WAAS satellites, making 18 satellites in total! As it was tracking the WAAS satellites, it is indicating 'code differential' mode.
