Collecting Almanacs
2.
Turn on the receiver. Wait for about 15 minutes while the receiver collects
almanac data from satellites.
Notice: If 15 minutes have passed and the receiver does not lock
on to satellites, you may need to clear the NVRAM. See
“Clearing the NVRAM” on page 4-14 for this procedure.
You will need to collect or update the almanac:
• 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 a few hundred kilometers at least.
• After loading a new OAF.
• After loading new firmware.
• After clearing the NVRAM.
• Before surveying.
The collection and/or update of an almanac can take as long as 15 minutes.
