摘　　要：可靠的通信链路是实现机载GPS信息有效传输的关键。介绍了频移键控（FSK）调制和解调技术；设计了在普通模拟电台语音信道上实现数据传输的硬件接口电路；提出了利用该接口电路和VHF／UHF常规电台建立机载GPS战术数据链的设想，并对该机载GPS战术数据链的误码率和传输距离进行了分析。该数据通信链易于实现，可广泛应用于各种无线数据传输领域。A reliable communication link is the key to realize airborne GPS data valid transmission. The paper introduces the operational principle and the translation performance of FSK modulation and demodulation, and designs the hardware interface circuits for transmitting data through the speech channel of common simulation radio. The paper puts forward the idea of establishing the airborne GPS tactics data link based on the interface circuit and VHF/UHF common radio, and analyzes the missing code ratio and transmission distance of the airborne GPS tactics data link. The link is useful and easy-to-realize, and it can be applied abroad on wireless data transmission area.
