We simulate some scenarios that 2/3 LEO satellites enhance 3/4/5 GPS satellites, to assess LEO-augmented GPS RTK positioning in signal-degraded environment. The effects of LEO-augmented GPS RTK in terms of reliability, availability and accuracy are presented, and the DIA algorithm is applied to deal with the poor data quality.
