Abstract
A navigation aiding system primarily for aircraft consists of a number of spaced apart ground stations. A ranging signal is transmitted to each of a number of aircraft in turn in response to received interrogation signals. The system allows a clock carried by each aircraft to be accurately synchronised with a master clock on the ground to permit the range to be measured precisely.
