Second FOC Galileo satellite already processed by magicGNSS!

March 20th, 2015 by Guillermo Tobías

As mentioned in a recent article by GPS World (, “On March 17, some stations participating in the International GNSS Service Multi-GNSS Experiment acquired E1 and E5a signals from Galileo 6 (FOC-FM2, GSAT0202). The satellite is using pseudorandom noise code E14.”

Analysing the RINEX data collected by the MGEX network, it seems that at least one clock correction (between 2015/03/19 00:40:00 and 02:00:00 UTC ) has been applied to the on-board atomic clock.

A magicODTS scenario has been configured using MGEX stations and removing all data for E14 prior to that apparent clock correction. The obtained results are below.

Satellite code-phase and carrier-phase residuals:

E14 apparent clock estimation w.r.t WTZZ station:

Apparent satellite clock stability:

Not enough data has yet been collected (roughly 24 hours of data) in order to perform a consisteny analysis, but the initial estimation shows an apparent clock behaviour for FOC-2 satellite which is in line with the expected performances from the Galileo satellites.

These are great news for the Galileo project!!
