GPS-Functions
The GPS-System allows the ARF-MikroKopter to
hold on to a position or automatically fly back to the
starting point.
Those functions are so called:
–
PositionHold
and
–
ComingHome
(assigned to a 3-way switch (OFF/ON/ON) on the transmitter )
Via a 3-way switch on the transmitter you can switch between the functions:
–
Position 1 => GPS-Function switched OFF (Free flight)
–
Position 2 => Function PositionHold activated
–
Position 3 => Function ComingHome activated
If you use one of these functions the altitude control should be also enabled.
PositionHold:
If the function PositionHold is activated the copter holds the actual position.
Here, the ARF-MikroKopter can, depending on the received signal from the satellites and the accuracy of the GPS-
System move around its position (1-3 m).
If you move the sticks on the transmitter the copter will move in the appropriate direction. If you release the sticks on the
transmitter the copter will hold the new position.
ComingHome:
Switching ON the function ComingHome the ARF-Mikrokopter will automatically fly straight back to the point where the
copter was started.
Important: The copter will use a pre-set altitude for the flight back, which is set in the settings for ComingHome-Height
( e.g. 50m).
This value can be set in the KopterTool in the tab „Easy Setup“ and „ ComingHome Height “ individually if necessary.
(See Page 20 – Easy Setup )
This under "Coming Home-height" listed altitude is also used for the FailSafe function!
In order for the use of the GPS-Functions a Satfix is needed. To get a Satfix it can take up to a few minutes
after switching ON the
ARF-MikroKopter. .
Is a Satfix available a short confirmation beep sounds up. The blue LED on the MK-GPS module under the
cover starts blinking in intervals.
If you switch ON the function PositionHold or ComingHome without a Satfix a „beep tone“ sounds from the
buzzer in second-intervals. The beeps go OFF if a SatFix is available or if the function PositionHold or
ComingHome is switched ON again.
The GPS-Functions can be disturbed through solar storms or other influences e.g. magnetic interferences.
If you determine that the copter shows unusual behavior using a GPS-function in that case switch OFF all
GPS-functions
immediately and fly and land the copter manually. Otherwise the copter may cause a crash
or could fly off.
