During the survey process, the right box will show the current survey status:
Position is invalid: base station has not yet reached a valid location;
In Progress: survey is still in progress ；
Duration: The number of seconds that the current surveying task has been executed;
Observation: the number of observations acquired;
Current Acc: Absolute geographic accuracy that the current base station can achieve;
Green bar at the lower part of the Mission Planner page shows the satellites being detected and
the signal strength related to each satellite. At least eight or more satellite signals are guaranteed
to exceed the red line ( Only when the satellite signal exceeds the red line is the effective number
of satellites).
The base station needs a certain amount of time to meet the accuracy requirements of your
input. Testing shows that, in an open area without shelter, to achieve the absolute accuracy of 2m
takes a few minutes; to reach the absolute accuracy of less than 30cm takes around an hour; to
reach the accuracy of 10cm takes a few hours.
It should be noted that the absolute geographic accuracy of the base station here will affect the
absolute geographic accuracy of the rover module without affecting the relative accuracy
between the base station and rover. If your application does not require UAV with high absolute
geographic accuracy, you do not need to set the base station’s precision too high, resulting in
long survey time.
Even if the accuracy of the base station is 1.5 to 2 m, the position accuracy of the rover module
relative to the base station can still reach centimeter level.
After the survey is complete, Mission Planner will display the following page:
