You may be wondering how differential GPS work. It works as the receivers of the GPS compute the distance via calculating the time that signals take in travelling from satellites. To calculate all this you need signals from 4 different websites. In differential GPS the receiver is basically placed at a certain point which is accurately worked out. On the other hand the stationary receiver replicates the entire process for all noticeable satellites. The receiver starts working backwards and it actually uses already measured position in order to calculate time. Finally it compares the time that signals should take with the actual time they took for reaching the station. The difference in the reading provides the error.

Hence a differential GPS system basically eliminates all chances of common GPS errors. This makes this the most reliable device available in the world. For getting the best results you must carefully read the user manual.
