Methods comparison

The two figures below reflect the actual horizontal errors of our PPP software, in real time, using the standard  method (left figure, real-valued ambiguities), and the ambiguity resolution method (right figure, integer-valued ambiguities), for the FFMJ00DEU0 station (only GPS/GLO L1/L2 here):

Horizontal positioning errors (last 6 hours)

PPP monitoring

Several monitoring cases are presented here. They reflect the actual results of our PPP software, in real time, using the complete set of corrections provided by CNES. These corrections correspond to the standard clocks, with additional biases needed for user integer ambiguity resolution. 

The following figures represent the real-time positioning errors (sliding window over one day), for a selected set of stations globally distributed:

NB: FFMJ and PAT0 stations are in GPS/GLO L1/L2 mode, others are full-constellation full-frequency
