The parameter values that set the quality with which data will be acquired are set in this section.

 

 

Elevation Mask: Elevation value or zenith angle of the satellites below which they will not be used to calculate the data in sexagesimal degrees.

 

Maximum PDOP:  Empirical precision value of the position supplied by the GPS receiver above which any data acquired will not be considered valid. See glossary.

 

Min. Satellites: Number of satellites beyond which the GPS receiver commences to give positions.

 

Epochs: Number of observations made for each point surveyed. The time between every measurement is 1 second.

 

Accuracy: Horizontal and Vertical precision values below which the positions given by the GNSS receiver will not be considered valid, which affects surveying and setting out.
