Although there is no experience of flying on water in "Surface Mode", I think it is possible to control the altitude on water using "lidar sensor". （I don't think you can use "optical flow" for plane position control.） If you are on the water with GPS enabled, you should be able to fly at a stable low altitude using the "Surface Mode" using the "lidar sensor".

Hello there!! I am doing a ardupilot pet project currently with the MTF-01 sensor. I have issues with the deactivation of SURFTRAK_MODE (Surface tracking mode), even after setting the parameter to 0 (Do not track) my drone still shoots up when there is an object below. This is an issue as my drone requires manual RC control when going over obstacles. Is anyone facing a similar problem?
Hello. This aircraft uses INAV. Surface mode uses a lidar sensor to control altitudes within 8m. Althold mode uses a barometric pressure sensor to control the altitude without any altitude restrictions. Surface mode is used indoors and outdoors when flying low. This mode switching state Surface mode⇒Althold mode Not good Surface mode⇒Angle⇒Althold mode good Surface mode⇒RTH good Surface mode⇒WP good I use a 3 position switch to change the mode. Angle is placed in the center. Surface mode⇒Angle⇒Althold mode I'm glad if you can use it as a reference.
Thank you for your reply, what do you mean by Surface mode⇒Althold mode Not good Surface mode⇒Angle⇒Althold mode good ? Thanks again for your reply! @@ujiie123

Hello i use all the setting but my quard get shoot out after apply poshold,surface,hedgehold,altitude hold together, i dont know why ? I use inav 7.1 please help
@@ujiie123 shoot out in front direction . I use angle mode after bipass the switch to arm in angle mode . After that after hovering i turn on all ( posh hold , altitude hold , surface mode , headhold ) in one channel . When I turn on the drone get shoot out . Help ( i turn dead recording on though )
GPS + Mag is always in use, and if GPS cannot be received indoors, it automatically switches to optical flow. “Position hold” is possible when GPS is received during outdoor flight, right?
That is cool.
thank you
how about base ground is water ..do drone will keep dynamic up down up down ?

great job dude :) it s 3 INCH ?
Yes, it's a 3 inch propeller.

What is the state of "shoot out"?

Would I off the GPS

@@ujiie123 yes that's right .
すごい、室内でもGPSが撮れてるってことでしょうか？
これはOpticFlow & Lidar(MTF-01)のテストです。
OpticFlow & Lidar(MTF-01)は下方向を検出するカメラで平面（X-Y）位置を認識し、超音波距離センサーで高度（Z）を認識します。これをINAV機に搭載することでGPSが受信できない屋内などでポジションホールドができる様になります。

いつも、勉強になります。
自分も時間があればこのような機体作成を行ってみたいと思いました。
かっこいいなー
ありがとうございます。
@@ujiie123 この凄さって中々伝わりませんよね。ロングレンジチャレンジの際は是非誘って下さい! 何時でも早起きしますので!
新しいセンサーが出ていたのでテストしているだけですよ～。今までのセンサーは晴天の屋外で使用できなかった（明るいと動作不安定）＆ GPSとの使い分け、たとえば低空はオプティカルフローで上空はGPSのような事がスムースにできませんでした。昨日今日と屋外でテストしてます、まだ止まりが悪い（ブレーキ調整）のですが、このセンサーでうまくいくかも？
ロングレンジは機体調整はできているのですが、
@@ujiie123 オプティカルセンサーは地面状況の影響をかなり受けるようですね。水面とか鏡面は無理だと読みました。僕はそれでも十分だと思うのですが。。。
ロングレンジ明日とか早起きしていきますか?
3時とかに出発すれば13時半には戻れそうですよねー
