Pre-survey Preparation
GR-5 Operator’s Manual

If the receiver has an almanac, the time needed to search for and lock
onto satellite signals is considerably reduced.
The receiver regularly updates the almanac and ephemerides and
stores the most recent versions in its Non-Volatile Random Access
Memory (NVRAM).
Perform the following to collect Alamac and Ephemerides data:
1. Set up the receiver in a location with a clear view of the sky.
2. Turn on the receiver.
3. Wait for about 15 minutes while the receiver collects complete
almanac and ephemeris data from the satellites.
Collect or update the almanac and ephemerides under the following
circumstances:
• If the receiver has been off for a long time.
• If the last known receiver position, stored in the NVRAM, is
different from the present position by several hundred kilometers.
• After loading a new OAF.
• After loading new firmware.
• After clearing the NVRAM.
• Before surveying
NOTICE
If 15 minutes have passed and the receiver does not
lock onto satellites, clear the NVRAM. See
“Clearing the NVRAM” on page 5-17 for details.
