摘要
引入空间直线与平面约束条件,介绍了约束条件下的伪距定位数学模型,并利用约束条件下的伪距定位数学模型分别对单一伪距观测和组合伪距观测做了详细对比。结果表明,相同约束条件下单一伪距观测P1精度最高,组合伪距观测P1P2精度最高,最适合作为双频接受机采取观测值。
The space straight line and the plane constraint condition are introduced,and the pseudo-range positioning mathematical model under the constraint condition is introduced. The results show that the single pseudo-range observation P1 has the highest accuracy under the same constraint condition,and the P1 P2 is the most accurate and the most suitable is the most suitable for the combination of the pseudo-range model. As a dual-frequency receiver to take observations.
