Urgent OmniSTAR beam change for North America

Due to a change being required by our satellite beam provider, the OmniSTAR satellite beams in North America will transition to one new single satellite beam. The three OmniSTAR MSV beams are now being consolidated into one single beam, CONNA, covering all of North America including most parts of Canada. The single beam, CONNA, will go live on Tuesday June 15, 2021. All users of the current MSV(-C,-E,-W) beams will need to migrate to the new CONNA beam during a 6 week overlap period, with a frequency and baud rate settings change on their GNSS receivers before July 26, 2021.

For more information, contact Customer Care.
