BDS/GPS融合定位中系统偏差补偿模型及其性能分析
|
Abstract:
多系统的融合定位可有效提高用户导航定位的连续性、可靠性及定位精度。针对BDS、GPS观测量间存在系统间偏差的实际情况，建立了顾及系统误差的BDS/GPS融合定位模型，即在函数模型中增加附加参数来吸收系统间偏差，构造了新的顾及先验信息的融合定位模型，分析了这种新融合模型的特点及其对定位结果的影响。利用不同品牌接收机在中国不同地域对新的融合模型进行试验，试验结果表明：BDS、GPS观测量存在系统间偏差，且不同接收机的系统间偏差量值并不一样；增加系统参数的融合定位模型能较好地吸收BDS、GPS观测量的系统间偏差的影响，改善其融合导航定位性能；在观测卫星数不足、单系统不能定位的情况下，考虑先验信息的融合定位模型仍能获得较好的定位结果
