†Corrupted FAT File Allocation Table
on PCMCIA card has
been corrupted and
could not be recovered
by the receiver. Format the card by sending $PASHS,FIL,D,999
or $PASHS,CLM or DELETE ALL on the
display. If some critical data is on the PC card,
send it to Customer Support who will try to
recover it.
Not Receiving Base
Data Not receiving RTK
Carrier Phase
measurements from
the base receiver Check serial/radio link with the base. Ensure base
is computing a position. Ensure a valid position
was entered into the base.
Not Receiving RTCM
Base Data Not receiving RTCM
code phase corrections
from the base receiver Check serial/radio link with the base. Ensure a
valid position was entered in the base. Check base
is computing a position.
Bad Base Coordinates The position entered
in the base receiver for
CPD operation is not
correct (too far from
computed position) • Base position was entered wrong on the rover
side. Reenter it.
• The mode in the base receiver was set to not
send BPS, set base to send BPS ($PASHS,
CPD,UBP,1).
• If rover is in “entered base station”
($PASH,CPD,UBP,O). Enter the base position
in the rover via $PASHS,BPS,POS.
• If rover is in “receiver base position” mode
(default or $PASHS,CPD,UBP,1), check link
with base.
• Make sure the base sends base coordinates
($PASHS,BPS,PER,O)
Bad RTCM Base
Position The position entered
in the base receiver for
RTCM code
operation is not
correct (too far from
computed position) Enter correct base position.
†‡Not Enough
Satellites Tracking less than the
minimum number of
satellites required for
kinematic survey The kinematic survey must be reinitialized on last
point.
Low Backup Battery The battery powering
the non-volatile
memory and the real-
time clock is low and
needs to be changed Contact Customer Support. Back-up battery must
be replaced.
