Change in the EGNOS system


In March 2017 the availability of the geostationary satellites which broadcast the correction signal EGNOS is adapted.

On 20th March the satellite 123 will be activated for operations. The satellite 136 will be transferred from operating mode into test mode on 21st March. Therefore its signals cannot be used any more by GPS receivers. From 21st March the new EGNOS constellation consists of the active satellites 120 and 123.

We therefore recommend to check the settings of the GPS receivers A100, A101 and AG-STAR and if necessary to adjust the satellite 1 on “120” and the satellite 2 on “123”. Alternatively, you can adjust the satellite 1 on “Auto”. Then the GPS receiver automatically determines the available satellite. In the operating manual of your Müller-Elektronik terminal you get to know how the setting of this configuration has to be carried out. >> Manuals on our Website
