1. Check OSD data output cable is normal or not.
2. DVL2 of the air system needs to be powered
again.
3. OSD MODULE needs to be powered again.
The quantity of GPS
parameter in the
display is 0.
GPS is not positioned
normally.
1.Chech the supply voltage ( DC 5V) and the
connection cable is normal or not,
2.When GPS is not used for long time, the battery
power memory is too low and ephemeris data lost,
RESOLUTION: The GPS need to re-download
21
ephemeris data, the first boot speed will slow down,
GPS cold start is generally 1 minutes or so.
3.As GPS satellite orbits all the time, GPS signals
could be effected by different time and places and air
cover like clouds layer, very tall buildings.
RESOLUTION: Change places or Period.
Display Parameter
D( Distance) is 0 or
wrong.
The distance is not
obtained correctly.
1.After OSD MODULE powered on, The starting
place should be saved (Don’t move the GPS’s
position) when GPS latitude and longitude values are
stable, which the values could be displayed ,then the
distance starts account.
2. The distance is re-accounted again or the value is
incorrect, the air system of DVL-2 and OSD
MODULE should be re-charged again.
