There are many applications, however, that demand levels of accuracy, integrity, availability, and continuity beyond even what a GPS PPS receiver can deliver. For such applications, augmentation is ...

Description: G timing requirements Ideal for global deployments due to GPS, BeiDou, Galileo, and GLONASS reception Unaffected by ionospheric errors Differential timing mode for highly accurate local ...

Also called a "differential GPS" (DGPS), an augmentation system compensates for those discrepancies by transmitting corrections to the GPS receivers either via satellite or terrestrial radio.
