How To Register 2 Drones With Faa

When the Mavic ii Pro and Mavic ii Zoom drones were released in August, the Precision Landing characteristic was not included. Many people who upgraded from other DJI drone models were upset that this feature was not carried over to the Mavic 2 and a long argue started over in this thread in the DJI forum. DJI eventually gave in and decided to add Precision Landing in the latest Mavic 2 Pro and Mavic 2 Zoom firmware release.

Prerequisites for using Precision Landing

In gild to apply Precision Landing on the Mavic two, y'all'll need to install firmware version i.00.02.00 (or higher). Follow these instructions to update the firmware using DJI GO or the DJI Assistant 2 application. You should also install the electric current version of DJI GO 4 from the app store on your mobile device.

Differences when compared to other DJI drones

When using Precision Landing with other DJI drones, yous need to enable information technology in the post-obit section of DJI GO:

And when using the auto takeoff feature, you need to tick this box to ensure the takeoff point is recorded:

Neither of these settings are displayed in DJI GO when flying the Mavic 2. The takeoff point is automatically recorded each time you accept off. All y'all need to do is ensure you lot have off properly and are flying in conditions where the Precision Landing feature tin exist used.

How to use Precision Landing

In gild for the drone to be able to precisely country, you'll need to practice the following:

1) Wing during the twenty-four hour period when there is sufficient light

The Mavic will not exist able to record the takeoff bespeak if the ground is not sufficiently lit. That ways you lot'll need to fly during the twenty-four hour period or in a location that has brilliant lighting (similar a baseball game stadium).

Annotation: The lights on the bottom of the Mavic are not vivid enough to illuminate the ground when flying at nighttime. If you rely solely on those lights for illuminating the landing area, the Mavic will likely country in a random location that is within a 10 foot circle of the takeoff point.

2) Cull a takeoff spot that has distinctive features.

When the Mavic returns home, it'll need some type of landmarks on the ground to use every bit a reference betoken. If taking off from a location that has a large bridge of compatible ground (like a large grassy field), you lot'll demand to lay some kind of marker on the footing below the Mavic. You can employ something similar a 3×three inch piece of brightly colored Plexiglas or a landing pad — like 1 of these:

FStop Labs landing pad
Freewell Gear landing pad
Hoodman landing pad

3) Brand sure the terrain does not change after taking off.

When the Mavic returns home to land, information technology'll endeavour to match up the previously recorded terrain to the current terrain. Whatsoever meaning changes in the terrain could reduce the accuracy of the landing.

four) Wait for the home betoken to be set.

If the Mavic has a good GPS signal, the home point should be automatically marked afterward the motors have been started. Cheque the map in DJI GO to ensure the "H" symbol is marked in the correct location.

5) Arise straight up when taking off.

When taking off, it'southward important to ascend straight upwards above the home bespeak for at least 23 feet (vii meters) earlier moving the Mavic in any management horizontally. That will allow the Mavic to properly record the takeoff location. There is no demand to hover in place later the Mavic has ascended to at to the lowest degree 23 feet (the takeoff indicate has already been recorded at this point).

Note: The speed at which y'all ascend (wearisome or fast) will not affect the accuracy of the landing. You can even accept off in Sport fashion.

Landing Procedure

Precision Landing is only used when Return To Abode (RTH) is initiated and the Mavic automatically returns home and lands. That tin occur if either you manually initiate RTH past holding the RTH button on the remote controller (until the remote controller starts beeping) or the Mavic automatically returns habitation due to a depression battery or lost remote controller bespeak.

After the Mavic returns back to the home point, information technology will right its heading (betoken in the management it took off) and begin descending. In most cases, the Mavic will exist too high in the air for the downward sensors to detect the ground below. Until the downward sensors are inside range of the ground, the Mavic will likely not be descending direct over the takeoff spot.

Every bit you sentry the Mavic descend, a Locating Landing Betoken message will pop up on the left side of DJI GO (like in the screenshot below) and you'll run across the Mavic correct its position equally needed. Information technology will do further corrections (if necessary) when information technology gets even closer to the ground. And if all works as designed, it should end upwards landing within virtually six inches of the takeoff spot.

Cancelling the landing

In some cases, the Mavic might non exist able to precisely locate the takeoff indicate when landing. When that occurs, it could stop up landing as far as about 10 anxiety away from the abode point. If yous notice that'due south about to happen and that location is not a safe landing spot, you can cancel the auto landing by apace pressing and releasing the RTH (or pause) button on the remote controller. At that betoken, the Mavic volition hover in the air and wait for you to manually finish landing.

Notation: It's best to cancel RTH when the landing is non going as expected. Don't effort to counteract the landing process by pressing the throttle upward or attempt to steer the Mavic to a different location. E'er cancel RTH first and then yous are able to take full control of the Mavic.

Using Precision Landing at night

Precision Landing will not work at night even if the down lights are set to auto on or on when taking off. While those lights are extremely helpful when taking off and landing in poor lighting conditions, they do non produce enough light for the downward sensors to record the takeoff area.
