Symptom
Possible Solution
No heading or incorrect
heading value
•
Check CSEP value is constant without
varying more than 1 cm (0.39 in)—larger
variations may indicate a high multipath
environment and require moving the
receiver location
•
Heading is from primary GNSS antenna to
secondary GNSS antenna, so the arrow on
the underside of the V200s is directed to
the bow side
•
$JATT,SEARCH command forces the V200s
to acquire a new heading solution (unless
gyro is enabled)
•
Enable GYROAID to provide heading for up
to three minutes during GNSS signal loss
•
Enable TILTAID to reduce heading search
times
•
Monitor the number of satellites and SNR
values for both antennas within
PocketMax—at least four satellites should
have strong SNR values
•
The volume of data requested for output
by the V200s could be higher than the
current baud rate supports.
No DGPS position in
external RTCM mode
•
Verify the baud rate of the RTCM input
port matches the baud rate of the
external source
•
Verify the pinout between the RTCM
source and the RTCM input port (transmit
from the source must go to receive of the
RTCM input port and grounds must be
connected)
