摘　　要：兼具高精度和采样率等特性的差分GNSS接收机具有出色的性能,被广泛应用于动态高精度实时定位场景,但在数据存储和传输环节中,存在GNSS卫星观测数据量显著增加及无线传输速度限制导致的数据包丢失的问题。因此,本文设计了一种动态可变字节的数据实时压缩及还原算法,有效解决了数据传输过程丢包的问题。The differential GNSS receiver with both high precision and sampling rate has excellent performance and is widely used in dynamic high-precision real-time positioning scenarios.However,in data storage and transmis-sion,there are problems of packet loss caused by the significant increase in GNSS satellite observation data and the limitation of wireless transmission speed.Therefore,this paper designs a dynamic variable byte data compression and restoration algorithm,which can effectively solve the problem of packet loss during data transmission.
