| 摘 要： | 可靠的通信链路是实现空地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GPS空地通信链的设想，并对该GPS空地数据通信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。

| Abstract: | A reliable communication link is the key to realize GPS data valid transmission between space and ground.The paper introduces the operational principle and the translation performance of FSK modulation and demodulation,designs of the hardware interface circuits for transmitting data through the sound path of common radio,The paper puts forward the idea of establishing the space-to-ground communication link based on the interface circuit and VHF/UHF common radio,and it analyzes the missing code ratio and transmission distance of the GPS communication link.The link is useful and easy-to-realize.It can be applied abroad on wireless data transmission area. |
