May 16th, 2007: NovAtel OEMV Firmware Version 3.20

Filed under: Firmware Updates/Info

NovAtel Logo

The latest OEMV firmware version 3.20 has been released. This new version has several improvements and features. One of the most anticipated addition is the automatic beam selection for OmniSTAR satellite based DGPS corrections. Prior to this feature, a command to change the frequency had to be issued. The automatic beam selection eliminates the need for manually setting the frequency.

Other improvements include: Improved Troposphere Model, GPS+GLONASS positioning, and AdVance RTK (technical white paper, PDF). A complete list of changes since version 3.10 is shown below.
