Real-time differential correction (RTDC) is a process where the reference station sends correction data to the rover via a radio or cellular link as soon as it receives the GNSS signals.

Real-Time Kinematic (RTK ... on signals from satellites and requires a base station for correction. Differential GPS (DGPS) improves accuracy by receiving corrections from a nearby fixed station ...

Differential correction can be applied in real time at the data collection phase or in the office, at the post-processing phase. The simple setting of the Differential GPS (DGPS) involves the ...

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.
