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].
