摘要：
Pseudo-range is a significant observable in satellite navigation systems. It is usually related to clock deviation, equipment time-delay and many other basic conceptions. Compared with the existing comprehensions, the specific conceptions and definitions are given of pseudo-range, clock deviation, real range (propagation time), and equipment time-delay, etc. Their relationships are also deduced. At last, the way how to measure and evaluate equipment time-delay, and how to estimate the precision of pseudo-range is discussed in details. Some conclusions and suggestions are also given.
