NovAtel's Waypoint Products Group offers real-time and post processing position determination software. A coordinate conversion tool, capable of batch conversions, is available on these software. User would need to inquire this group for more details:
There are also lots of coordinate conversion tools available online. Our engineers verified our receiver output comparing random world-wide positions with an application from NRCan:
User can compare conversion tools or algorithms use to what our receiver computes by fixing the position and then logging the resulting BESTUTM to see what the receiver came up with. The algorithm used in our receiver for Lat-Long UTM conversion, can be easily found in map projection text books. User can fix the position of the receiver only using Lat-Long coordinates.
