GNSS Status Information

GNSS Status Information displays a snapshot of the current GNSS
status information.
1. Press .
View Status
2. View data including:
◄Baud Rate – the current status of the GNSS
◄Baud Rate Status – the rate at which information is
transferred/ communicated.
NOTE: a minimal baud rate maybe required for some
software version to work at their peak performance.
◄GGA/VTG Data Rates – the number of GNSS positions per
second.
◄Number of Satellites – the number of GNSS satellites in view
(minimum of 4 are required for DGPS)
◄HDOP – a measure of satellite geometry strength in the
horizontal plane. A HDOP value of less than 2 is preferred.
◄PRN – the current DGPS satellite ID
◄GGA Quality – the current quality indicator of the GNSS signal
(see GGA Requirements chart)
◄Receiver – the current indicator of the receiver
◄Receiver Version – the software version installed on the
receiver
◄UTM Zone – zone where currently located (see "UTM
Coordinates and Zones" in this manual)
◄Model – the correction models available to be used with the
current receiver configuration
