Epochs to Average on Accept

: 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.
