ILRS logLARGE campaign to begin February 15Release Date: 02/06/2018The first LARGE Campaign for 2018 will run from February 15 to May 15. Each GNSS constellation has identified 4 primary and 4 secondary satellites for tracking:

GLONASS-131, -134, -136, -137
Galileo-102, -202, -209, -210
Compass-G1, -I3, -M3, -MS1

GLONASS -128, -132, -133, -135
Galileo-103, -203, -211, -213
Compass-I5, -IS2, -I6B, -MS2

Please refer to the ILRS priority list on February 15 for the exact priorities. Also note that in April, the list of secondary satellites for Galileo will change as per request from the mission.


During the campaign, the ILRS will provide GLONASS, Galileo, and Compass predictions to the stations for ONLY THESE SELECTED SATELLITES in order to encourage stations to focus on only these targets.

Stations are requested to track the primary satellites over at least two, preferably three, widely spaced segments over the arc, with each segment containing at least two normal points. For the secondary satellites, stations are asked to track at least one segment with at least two normal points over the arc. If some of the primary satellites cannot be tracked due to daylight, weather conditions or other reasons, then we are asking the stations to put more emphasis on the secondary satellites.
