If your Trimble mobile data collection device has been stored away for the winter it is important to reset your GNSS/GPS receiver before data collection. Resetting the internal receiver will delete the existing almanac from the device. The almanac file provides approximate orbit information for all satellites in the constellation. Using an out-of-date almanac can cause issues when connecting to satellites. It will take approximately 20 minutes to fully reset the receiver and download the new almanac. An open, outdoor environment is also required.
Resetting the receiver can be simply performed using one of these programs:
- GPS Controller (free download)
- Trimble Positions
