GNSS GBAS Freq RNAV
GBASGBAS —Ground Based Augmentation System identify any errors in the GPSGPS —Global Positioning System (USA) signal by comparing their known position to their GPSGPS —Global Positioning System (USA) position. The difference between the two is then transmitted directly using VHFVHF —Very High Frequency, line of sight, waves. The signature difference between this and SBASSBAS —Space Based Augmentation System is that SBASSBAS —Space Based Augmentation System uses UHFUHF —Ultra High Frequency to transmit the correction via satellites.
