Control of GPS Common View Errors in an Autonomous Time Synchronisation System

Steve Simpson, Keith Stribley

Abstract:	The paper is based on continuing work to develop a GPS time transfer system for synchronisation of a multilateration system for measuring the height of aircraft. The target is to synchronise any pair of reception sites such that the mean time error between them is zero with a standard deviation of 1 nS. The work to date has characterised the performance of a system using carrier phase smoothed code-tracking receivers with both Rubidium and Caesium clocks. The Allan Deviation uncertainty characteristics of the main components are examined and a synchronisation error budget is developed. The findings to date suggest that it is extremely difficult to stay within budget without adaptive clock tracking or carrier phase tracking receivers.
