After its launch back on March 27 , Galileo-FOC FM4 (GSAT0204) started transmitting on May 21th at about 11:32 UTC, being tracked at that time by the International GNSS Service Multi-GNSS Experiment tracking station in Windhoek, Namibia with PRN E22 (http://gpsworld.com/newest-galileo-satellites-now-transmitting/).

As for the previous FOC satellites, a magicODTS scenario has been configured using MGEX station data for May 23rd and May 24th, and setting WTZR as reference station.

The obtained results are below. Satellite code-phase and carrier-phase residuals:

The following plot shows the Galileo-FOC FM4 apparent clock estimation w.r.t WTZR station:

Following you can find the GPS and Galileo clock stability:

From the above results it seems as the IOT for Galileo-FOC FM4 is running quite smoothly,  let’s hope Galileo-FOC FM3 starts transmitting soon too!

Congratulations to ESA and the Galileo project!!
