Takes Too Long for CSM to Come INS

This problem may be caused by a delay in GPS acquisition. Check the

accuracy flag status and/or current position. Refer to the GSM system

time/GPS and LFR/HSO verification section in Chapter 3. At least one

satellite should be visible and tracked for the “surveyed” mode and four

satellites should be visible and tracked for the “estimated” mode. Also,

verify correct base site position data used in “surveyed” mode.
