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.
