      Header:DJIRTK.h
      Description:

      Determines if RTK is enabled. Phantom 4 RTK has different behavior from the other products that supports RTK:
      - For aircrafts except Phantom 4 RTK, disabling RTK will stop RTK from pushing valid position.
      - For Phantom 4 RTK, RTK will continue to push latest RTK coordinate if there is strong satellite signal after disabling RTK. However, the flight controller will not use the RTK coordinate for navigation. It's supported by Matrice 210 RTK, Matrice 210 RTK V2 and Phantom 4 RTK.

      Input Parameters:
      BOOL enabledYES if RTK is enabled.

      RTK Maintain Positioning Accuracy Mode
      method
      setRTKMaintainPositioningAccuracyModeEnabled:withCompletion
      method setRTKMaintainPositioningAccuracyModeEnabled:withCompletion
      - (void)setRTKMaintainPositioningAccuracyModeEnabled:(BOOL)enabled withCompletion:(DJICompletionBlock)completion
      Header:DJIRTK.h
      Description:

      Sets RTK maintain position accuracy mode enable. When enabled is TRUE`, the aircraft will maintain position accuracy about 10 minutes after losing RTK signal. Only supported by Phantom 4 RTK. When the aircraft is in Maintain Positioning Accuracy mode: 1. The aircraft positioning accuracy will decrease gradually. Be sure to fly with caution. Stop the flight or reconnect to the RTK signal source immediately to avoid flight hazards. 2. Flying the aircraft for a long distance (for example, automatically performing operations alongside the planned flight route), or controlling the aircraft with a large stick movement will lead to faster positioning accuracy decrease. 3. The RtkFlag of the images the aircraft captured is 16(Point Positioning), which cannot meet the requirements for mapping. It is not recommended to use Maintain Positioning Accuracy mode in flight route operations, especially in operations with an absolute altitude. This mode is more suitable for inspection or waypoint operations.

      Input Parameters:
      BOOL enabledYES to enable RTK maintain positioning accuracy mode.
      DJICompletionBlock completionThe completion block that receives the execution result.
      method getRTKMaintainPositioningAccuracyModeEnabled
      - (void)getRTKMaintainPositioningAccuracyModeEnabled:(void (^)(BOOL enabled, NSError *_Nullable error))completion

      Input Parameters:
      BOOL enabledYES if maintain position accurary mode is enabled.
      void (^)(BOOL enabled, NSError *_Nullable error) completionThe completion block that receives the execution result.
