= Info / Function =

'''A GPS system on the copter is required for the GPS function ''!PositionHold'' (PH).'''
<<BR>><<BR>>

If there is no control movement for "Nick" and "Roll" on the transmitter, the !MikroKopter hovers alone and is exposed to the wind.<<BR>>
The copter can leave its current position more or less quickly.<<BR>><<BR>>

The ''!PositionHold'' function makes it possible to hold the !MikroKopter at its current position in the air at any distance. 

For this, the copter uses its current GPS position. This is retained until a new control command is received via the transmitter.<<BR>><<BR>>

To be able to use this function:
 
 * a free 3-way switch is required on the remote control. <<BR>>
 This is assigned a free channel (e.g. channel 6) 
 
 * the GPS function is activated in the !KopterTool and assigned to the same channel (see [[en/MK-Parameter/Easy-SETUP#GPS|GPS setting|target="_blank"]])

The 3-way switch then has the following switch positions / functions:
 
 * OFF - No function
 * Middle - ''!PositionHold'' (PH) function ON
 * ON - ''!ComingHome'' (CH) function ON


If the 3-way switch is then in the middle position (PH) and the sticks for pitch and roll are in the middle position, the copter maintains its current position.<<BR>>
If the control stick for "Nick" or "Roll" is then moved, the function ''!PositionHold'' is automatically deactivated and the copter flies to the new controlled position.<<BR>>
If you let go of the control sticks for "Nick" and "Roll" again, the function ''!PositionHold'' is automatically activated again and the new position is retained.

INFO: The 3-way switch can always remain in the middle position (when taking off / flying / landing).
