the field by software download. CSM kit SGLN1145 and SGLN4132
must have proper reference sources configured (as shown below) to
function correctly.
CSM Kit No.
Hardware Configuration CSM Slot No. Reference Source Configuration
SGLN1145 With GPS Receiver 1 Primary = Local GPS

Takes Too Long for CSM to
Come INS
This may be caused by a delay in GPS acquisition. Check the accuracy
flag status and/or current position. Refer to the CSM system time/GPS
and LFR/HSO verification section in Chapter 3. At least 1 satellite
should be visible and tracked for the “surveyed” mode and 4 satellites
should be visible and tracked for the “estimated” mode. Also, verify
correct base site position data used in “surveyed” mode.
