What does the real time kinematic require for receiving satellite signals?

The correction signal is sent out at intervals of 1 second.

The base station can also be on a moving vehicle, in which case the corrections needs to be sent out at the sample rate of the receiving GPS engine, and the accuracy is slightly reduced to around 3 - 5cm.

It requires a radio antenna which connects sattelite to our GPS antenna for giving us accurate position within 3 to 5 centimeters.
