Abstract:The method for the Equipment Time-Delay (ETD) are analyzed and researched, then it is presented that the equipment time-delay should be a statistic with stability, so a ETD measurement method based on RF sampling and Software Radio (RFSR) is established, that can correctly get the ETD and the stability of ETD. This framework is valid and batter than ever by simulating, and measuring cables and Programmable Delay Line (PLA) in a testbed.
Keywords:satellite navigation  equipment time-delay  RF sampling  software radio
