Geo 7x with TerraSync
- If you are using data dictionaries, way points, or basemaps in your field work, transfer the files to the Geo 7x handheld following the instruction in the “Transferring Files” section on this page.
- If you will post-process your data, identify the base station you will use. You can use the CORS map to find the closest base station and if the station supports systems other than the US GPS. These information are required for the handheld to display the approximate accuracy of the positions to be collected, see section “Setting Accuracy Display“.
For high-accuracy position collections, the base station should not be more than 20km away from your field, and under 10km is desired.
As an example, you can find the closest base station on the CORS Map page by entering a place name or an address. Click the base station on the map to see if it supports systems other than the GPS.
- If you plan to use a real-time correction service that requires wifi or cellular service , make sure the communication service will be available at your field work site.
- Check if the battery of the handheld needs to be charged.
- If the handheld has been kept indoor for longer than two weeks or so, or has been transported for a long distance since it was last used, leave the receiver on under open sky for the receiver to get updated almanac. This will shorten the Time to First Fix in the field.
- If you are using the external antenna, learn how to connect the antenna with the range pole and the handheld. See section “Connecting the External Antenna“.
- Configure the handheld for your field work needs. See the other sections on this page for details.
