: is where you set the number of
epochs to average for the final coordinate. If this number is greater
than one, the final coordinate is calculated using an average of the
number of epochs specified.
Note: This function is not appropriate for every recei ver. Some
receivers, when dynamics are set to ‘static’, use Kalman filtering and
other superior techniques to cal culate an average position. In this
case, the position returned from the receiver is better with each epoch
and you may actually degrade your result by averaging with Survey
Pro. You should check with your receiver manufacturer for s pecific
recommendations on field procedure.
