GPS Height

Set up the GPS antenna height and geoid separation. If the GPS receiver is placed several meters above the ground, you can enter the antenna height. Then, when GPS is calculating position, the distance will be deducted and more precise position information could be obtained. For the same reason, you can enter the geoid separation to deduct the discrepancy. Please enter according to your preciseness request, or you can maintain the default. The default is 0 meter.
