Device for inputting RTK correction data to a GPS
First Claim
1. A communications system comprising:
- a GPS receiver that receives GPS position data and GPS correction data;
a mobile computing device located remotely from the GPS receiver and including a first transceiver, wherein the mobile device accesses RTK correction data over a cellular network using a current GPS position and processes the RTK correction data; and
a handheld adapter physically and removably coupled to the GPS receiver and including a voltage regulator and a second transceiver that receives the RTK correction data over a wireless signal sent by the first transceiver of the mobile device, wherein the handheld adapter converts the RTK correction data, transmits the converted RTK correction data to a serial port on the GPS receiver and derives power from the GPS receiver using the voltage regulator to power the handheld adapter.

Abstract
A communications system includes a GPS receiver that receives GPS position data and GPS correction data, a mobile device having a first transceiver and an adapter coupled to the GPS receiver and having a second transceiver and a voltage regulator. The mobile device accesses RTK correction data over a cellular network using a current GPS position and processes the RTK correction data. The second transceiver of the adapter receives the RTK correction data over a wireless signal sent by the first transceiver of the mobile device. The adapter converts the RTK correction data so that the RTK correction data is receivable by a serial port on the GPS receiver that the adapter is coupled and the voltage regulator derives power from the GPS receiver to power the adapter.

16. A communications system comprising:
-
a GPS receiver; a mobile computing device located remotely from the GPS receiver that accesses RTK correction data over a cellular network and processes the RTK correction data, the mobile computing device including a mobile device transceiver that sends and receives data signals; a handheld adapter physically and removably coupled to the GPS receiver and including a voltage regulator, a wireless transceiver in communication with the mobile device transceiver, and a RS232 transceiver in communication with the GPS receiver; wherein the voltage regulator derives power from the GPS receiver for operating the wireless transceiver; wherein the wireless transceiver receives a wireless data signal from the mobile computing device that contains RTK correction data; and wherein the RS232 transceiver converts the data signal received by the wireless transceiver to a RS232 data signal and communicates the RTK correction data to the GPS receiver. - View Dependent Claims (17, 18, 19)
