IAGNOSTICS
There are three main tabs under the DGPS button that
display detailed information about the GPS signal and
receiver. If the display is interfaced to an autopilot navigation
controller, an additional tab will be present with appropriate
diagnostic information.
• Latitude, Longitude, Elevation
Displays current position (in longitude and latitude) and
elevation.
• Heading
Displays degree heading of travel
• Number of Satellites
Displays the number of satellites currently being tracked by the receiver.
• Differential
If a TSIP receiver is being used, the differential status will display the differential source,( i.e. WAAS,
Beacon or OmniSTAR). This message field will display either Diff On or Diff Off.
- Diff On - indicates the receiver is receiving a differential GPS signal.
- Diff Off - indicates the receiver is not receiving a differential GPS signal.
• View Messages
To view the NMEA and/or TSIP messages coming from the receiver, press the View Messages button.

The Advanced Tab displays further diagnostic
information about the GPS receiver. The
Universal time, position errors (HDOP, PDOP),
GPS speed, and update rate are displayed for
receivers.
• UTC Time
UTC is an acronym for Coordinated Universal
Time, a high-precision atomic time standard that
defines local time throughout the world. Different
versions of universal time use atomic clocks to
correct for irregularities in the Earth's rotation and
orbit. UTC is used in navigation, astronomy,
aviation, Internet broadcasts, and amateur radio.
If you are receiving information from the satellite,
then the UTC Time should automatically update.
• HDOP
Horizontal Dilution of Precision (HDOP) indicates the quality of the horizontal GPS position. Lower HDOP
numbers are optimal, higher numbers are undesirable.
• PDOP
