Towards new CODE analysis products based on GPS L1/L5 signals

To meet the demanding requirements in terms of accuracy and availability, GPS has introduced the signals on L5 that are compatible to Galileo E5a signals. The L5 signal was designed to mitigate the multipath and poor performance in harsh environments such as indoor, forests, and areas affected by jamming. As the L2 signal will become obsolete in the future, action must be taken to take advantage of the modern signal type which is currently broadcast by 19 out of GPS satellites. This is particularly important for some future LEO satellites (e.g. EPS-SG) which will rely exclusively on L1/L5. CODE (Center for Orbit Determination in Europe) is building up a prototype processing chain to generate L1/L5-based clock and bias products in addition to the classic L1/L2-based processing chain. First results regarding analysis product consistency are presented.
