Return-to-Home (RTH)
The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point. There are
three types of RTH procedures: Smart RTH, Low Battery RTH, and Failsafe RTH. This section describes
these three scenarios in detail.
GPS
Description
Home Point
If a strong GPS signal was acquired before takeoff, the Home Point
is the location from which the aircraft was launched. The GPS signal
strength is indicated by the GPS icon ( ). The aircraft status
indicator will blink rapidly when the home point is recorded.
Smart RTH
Tap in the DJI GO app or toggle the S2 switch on the remote controller back and forth at least twice
to initiate Smart RTH. The aircraft will rst ascend to the Return-to-Home altitude, then return to the last
recorded Home Point if a GPS signal is available. During the RTH procedure, you may use the remote
controller to guide the aircraft around obstacles.
Tap in the DJI GO app or toggle the S1 switch once to terminate Smart RTH and regain full control of the
aircraft.
