attitude configuration
« on: March 16, 2019, 08:38:05 pm »
I'm trying to configure mu Revo for autonomous flight.
I wonder how to set "Attitude ---> Settings ---> Attitude Estimation Algorithm". Any gps set give configuration error when i choose "GPS assist" in "Input ---> Flight Mode Switch Settings ---> Assisted control".
I need assisted control flight and automatic waypoint flight to take photo on for vegetation inspections.

Thank you in advance.

My hardware and software:

Linux Debian 9
Librepilot Sep 29 2018 15:42

Frame: Realacc (zmr250)
FC: Open pilot revo
Oplink 433Mhz

Motors: Racestar BR2307s 2200KV Green Edition
Gps: GPS Module Ublox NEO - M8N
Battery: 3S 1350
Radio: no radio
  usb joypad

Should be "GPS Navigation (INS13)" to use the GPS for any flight modes or flight assist.

Thank you for th answer!
Using "GPS Navigation (INS13)" even if Attitude --> flight mode switch settings --> assisted control --> none

For those flight modes (head (headless?) position and flight plan) you need GPS flight modes.  For that you need INS13.  INS13 needs GPS and mag for all flight modes, even for flight modes that you would think do not need it.

It sounds like you have alarms.  In particular, INS13 won't arm until:
- you have GPS and mag installed correctly, configured correctly, and running correctly
- you have set home location
- mag is calibrated and green
- GPS has enough satellites to be green
- there are some flight modes it will not arm in, you must arm in other modes and switch to these
- there may be others I have forgotten...

You say that your mag is red.  That is at least one thing that will keep it from arming and flying.
Atti and Stab turn green after everything else is correct.
When Atti and Stab turn green you can arm.

You must also twist and carefully route your high current motor power wires (battery to connector, connector to PDB, PDB to ESC, ESC to motor) to avoid mag problems that only happen when motors are running with flight load (with props on).  Also, some PDB are not mag friendly.
