Updating the Home Point
You can update the home point in DJI Agras during ight. There are two ways to set a home point:
1. Set the current coordinates of the aircraft as the home point.
2. Set the current coordinates of the remote controller as the home point.
Make sure the space above the remote controller’s GNSS module (located inside the place above
the ight switch mode) is not obstructed and that there are no tall buildings around when updating
the home point.
Follow the instructions below to update the home point:
1. Go to DJI Agras and enter Operation View.
2. Tap
, then , and select in Home Point Location settings to set the current coordinates of the
aircraft as the home point.
3. Tap
, then , and select in Home Point Location settings to set the current coordinates of the
remote controller as the home point.
4. The aircraft status indicators blink green to indicate that the new home point has been set
successfully.
RTH Safety Notices
The aircraft cannot avoid obstacles during RTH if the operating environment is not
suitable for the radar module. Users can only control the speed and altitude of the
aircraft. Before each ight, it is important to set an RTH altitude that is appropriate for the
given environment. Go to Operation View in the app, tap , then , and Set Return to
Home Altitude.
3 m
If the aircraft is flying under 3 m and RTH (including Smart and Failsafe RTH) is
triggered, the aircraft rst automatically ascends to 3 m from the current altitude. You
cannot control the aircraft during this ascent. In Smart RTH, you can exit RTH to cancel
automatic ascent by pressing the RTH button once.
5 m
H
The aircraft automatically descends and lands if RTH is triggered when the aircraft ies
within a 5 m radius of the Home Point.
