Problem: GPS satellites are not displayed in the GPS skyplot

Solution or Workaround

Description

The GPS satellites are not displayed in the GPS skyplot when using the NMEA protocol, despite receiving valid coordinates from the GPS receiver.

Cause

The GPS receiver does not output the required NMEA message.

ArcPad supports nine NMEA messages. Some GPS receivers only output a small number of NMEA messages; sometimes only the minimum required to send the GPS coordinates. In order for ArcPad to display the GPS satellite constellation, it needs to receive the $GPGSV and $GPGSA NMEA messages.

Solution

Verify that your GPS receiver supports these two NMEA messages.
