Re: How to convert xyz to GPS coordinate

Thank you.
Lat= Lat_ref + y*9.013373

Long= Long_ref + x*8.98315*cos(Lat_ref/1000000)

Could you know why lat is more simple than long?

I am little confuse. I saw ardupilot discussion and it was very complex but it in here it looks very simple.

Re: How to convert xyz to GPS coordinate

Dear smoker I know your GUI interfaces. I just want to do fake geotagging using the modem. Since modem can give the beacon's x,y,z(which is the vitual place) I need to insert the GPS Longtitude, Latitude Altitude. Altitude=z What is Latitude= Longtitude= I saw some of formular in ardupilot forum. I ...

Re: Firmware and Params for autonomous flight (Link to firmware added)

Land mission worked for me. Loitering also worked.
Rtl seems dangerous both .
I have big accident middle of rtl. I need to make another UAV again.
Thanks. After test normal mission I will contact you. Next week is my final exam.

Re: Firmware and Params for autonomous flight (Link to firmware added)

EK3_ALT_SOURCE: Primary altitude sensor source I use: EK3_ALT_SOURCE = 2 EK3_GPS_TYPE: GPS mode control Note: This parameter is for advanced users This controls use of GPS measurements : 0 = use 3D velocity & 2D position, 1 = use 2D velocity and 2D position, 2 = use 2D position, 3 = Inhibit GPS...

Re: Firmware and Params for autonomous flight (Link to firmware added)

Dear hendrik
I read your parameter and did you use the laser sensor for altitude?
Your rng value is true and you are using the 2d positioning in EKF3 is it right?

Thank you.

Re: Firmware and Params for autonomous flight (Link to firmware added)

Hello hendrik. I am try to applying your firmware. There are some problems. First I yaw value is continuously moving. Prearm check yaw value feels strict. Second GPS North direction is moving. I don't know why maybe it is beacon's problem. I think second is temporary phenoman but first this is reall...
