The data comingįrom both GPS receivers is fed into the Controller which aligns the data so that data being collectedīy the rover receiver is automatically corrected to the position of the base. The latter is used for the actual surveying. The first is the staticīase station and the second the rover. The differential system uses two GPS receivers that record at the same time.
