Implementation of the Cityfix receiver concept

Cityfix is an integrated navigation system, which combines Differential GNSS and MW-radio transmissions. During outages or poor performance of the DGNSS the Cityfix system measures the carrier wave phases of the MW-radio transmitters to determine a displacement from the last accurate DGNSS position. This paper describes the implementation of the...

Positioning & Control of the Cityfix System

Position determination systems based on differential satellite systems can achieve a very high accuracy. The Eurofix system for example, can determine positions with an accuracy of 5 metres for 95 percent of the time. A problem that arises when using these differential satellite systems, is the bad reception quality of the satellite signals in...
