Abstract

The most promising and fully operational GPS (Global Positioning System) is a navigation system based on a group of 24 satellites developed by U.S. Department of Defence. Every satellite sends data to the receiver in the form of signals, having some information about satellite and orbital information. Even in worst weather conditions this GPS system is used to find out exact location with respect to timing information anywhere on the surface of globe. The HC-12 can transmit the information from a GPS receiver with no additional programming or circuitry. Remotely transmitted coordinates would have to be received by another HC-12 transceiver and then processed with a microcontroller or computer.HC-12 is wireless transceiver (43.3Mhz) which is used to transmit a data up to long range (*1.5Km) outdoor. Controller system is design on AVR controller system to process data from GPS and sends it to HC-12 receiver. On receiver side GPS receive data is decoded and send to the pc USB port. A interface unit (TTL to USB) is used between controller and pc.
