摘要
在抗差GPS/COMPASS实时差分定位的基础上,对比分析了等权随机模型、高度角随机模型和信噪比随机模型对导航定位的影响,并由此提出高度角信噪比联合随机模型。试验证明,该模型与等权随机模型相比,明显提高了定位精度,也优于高度角和信噪比随机模型。
The elevation angle and SNR Combined stochastic model was proposed in the paper, based on the- comparison of influence of different stochastic model-equal weight model, elevation angle model and SNR model on positioning, The result of analyzing the data from an experiment of vehicle running shows that this model is obviously superior to equal weight model and also better than elevation and SNR model.
