GPS-Based Time Transfer Using Low-Cost Receivers


GPS-based time transfer can be used to establish a traceable link between a national time standard and a remote user’s standard. Equipment cost can be a consideration in such applications, and the GPS receiver used can be a significant component of this cost. We consider the use of low-cost timing receivers in time transfer, establishing the requirements for such receivers. Three suitable receivers are characterized, using software we have written for the Open Traceable Time Platform, an open source project developing a system for legally traceable time and frequency. The tested receivers were found to be suitable for all but the most demanding applications.
