Satellite schedule
The satellite schedule shows predicted date and time when the GPS
receiver can fix its position by receiving GPS satellites. The time
varies according to DOP threshold and position-fixing mode set on
the GPS INITIAL SETTINGS menu.
Example 1
Indication: “24 HOURS OK”. (Position fixes by GPS available round
the clock.)
Example 2
1. 11:30
(GPS position fixes available from current time to 11:30 of the
same day)
2. 9/1 12:00
→
3:51
(GPS position fixes available from 9/1 12:00 to 9/2 3:51)
3. 9/2 4:05
→
(GPS position fixes available from 9/2 4:05 to 9/3 4:05.)
Frequency deviation
This indication shows how many Hertz the GPS receiver is deviating
from its assigned frequency of 1575.42 MHz. Less than about 3000
Hz is normal. Any deviation higher than that will mean more time is
required to fix position.
