GPS antenna array receiving machine

The utility model is a GPS antenna array receiver. An antenna array control circuit board is arranged in a shell of the receiver. A digital circuit on the circuit board is equipped with a radio frequency chip IC1, a relay circuit, and a liquid crystal display circuit. A GPS-OEM board is also arranged in the shell. An output end of the receiver is connected with the digital circuit via a radio frequency cable and the GPS-OEM board on the antenna array control circuit board. A control encoding chip IC2 and a RF chip of the digital circuit realize the non-interference gating of different GPS antennas, and switch a GPS input signal received by the GPS-OEM board from one antenna to a designated antenna at a certain interval according to a directive in a way of non-interference. A control circuit formed by a singlechip chip IC3 and a peripheral circuit of the singlechip supports inputs from an external digit keyboard. In addition, IC3 conducts the data communication with a PC (PDA) via a serial port chip IC6. The u
