Good base practice prevents errors that carry into everything you collect [1]:
- Verify the point: confirm the monument, its published or record coordinates, and the datum, epoch and geoid.
- Set up carefully: level and plumb the tripod, and measure antenna height twice, to the correct reference on the antenna.
- Enter the right values: coordinates, antenna type and height in the base and rover settings.
- Check in immediately: occupy a second known point with the rover before collecting data, and compare the horizontal and vertical residuals.
- Repeat checks during the day and at the end of the session.
- Record metadata: time, PDOP, satellites and any warnings.
If you work in a projected or ground system, confirm the scale factors and the project setup before the first shot [2].
