Revo not arming in mode that depends on GPS
« on: June 09, 2016, 04:20:34 pm »
I can not fly in the PositionHold or CourseLock mode, the revo no weapon. Even foxed with 10 satellites.

Stabilized1 in the mode the flights is very stable. Perfect.

I the battery runs dows the revo may interfere with the magnetometer?

see photos of how it is mounted.

If there is a GPS flight mode configured into the flight mode switch, Revo will not arm unless:
- Configuration -> Attitude -> Settings -> "Attitude Estimation Algorithm" is set to "GPS Navigation (INS13)"
- HomeLocation is set
- Mag (magnetometer) is calibrated
- Mag is green color in system health
- GPS is green color in system health

Besides that, all the high current motor wire pairs (and triples) must be twisted together with the pair becoming one cable.  If not, you may get a "fly away".

I recommend that you play with "Velocity Roam" flight mode because it is simple, safe, and more interesting than "Position Hold".  If you leave sticks in the middle it is the same as Position Hold.

The fact that you have it flying well in Stabilized1 (which is Attitude mode) is a good sign that you are almost there.

I changed the title of this to say "not arming" because the other was minor bad and could make readers afraid.  :)

Ok, thanks for the help.

The "Navigation GPS(INS13)" is enabled.

Now I need to confirm that "Homelocation is active" How do I know this?

and

Magnetometers are calibrated, but sometimes is not in green.
The Gps yes, is green.

in flight stabilized1 enough, I made up a video and posted on Youtube.

Flying in FPV and distance myself around some 700 meters.

OK, so it is probably Home Location.  To be honest I forget the standard user ways...  I suggest that you right click GCS GPS map (Flight Data) (tab) where you want to set it (zoom in and find yourself first), and select "set the home location" from the "right click list".  It will ask for altitude.  Enter altitude.

but I must stress that it is important to have motor power wire pairs twisted well.  Else mag goes crazy only when motors are running hard.  Crazy mag means it doesn't know where it is pointed.  Doesn't know where it is pointed means the harder it tries to get to where it should be the farther away it goes.  Fly away...  Because of this, please switch from Stabilized1 to VelocityRoam and be very ready to immediately switch back.  Football field size place at least for first try.

It is normal for mag to be green only sometimes when on the ground.  In the air it should be green almost all of the time.  It will let you arm when it is green.  Then it will stay armed even when not green.

I do not see my street, my house.

Even increasing or decreasing the zoom.

You must zoom in a lot more than that, so that slider is almost all the way to (+) to see houses.

Yes.  That screen works for altitude.  For all the GPS data you can expand DataObjects->GPSPositionSensor.  I think that the exact value for that value it wants when you set home location would be altitude + geoidseparation taken from GPSPositionSensor.  For me the numbers are altitude=300 and separation=-30 so the sum is 270.  Truly the exact value does not matter until you start doing absolute position waypoint flight.  It does not matter because everything is relative to starting altitude.  When you enter (examples) PositionHold or VelocityRoam mode, it gets the current altitude.  It does not matter if it thinks it is 100m or 1000m.  If the aircraft finds itself at 101 or 1001 it knows it must come down 1m and acts the same whether starting with a number 101 or 1001.  Only when you have absolute position waypoints and must fly close to ground without crashing does it matter.  And then you find out how badly inaccurate GPS altitude is.  You had better leave 5m above the ground or you will run into the ground sometimes.  Baro sensor helps for this in some cases.

I made an organization on the wires. The esc wires grouped into one, just left a wire with positive and negative, the other 3 just let the signal wire.

I pulled the fpv transmitter of revo.

Now I'll take the test and see how it was.

I will try to fly with the first VelocityRoam. Just flew in stabilized.

I mentioned that I did not locate me in the flight data my street and my house.

I realized that the latitude and longitude shown the flight data is different from that shown in the system.

see the photos

The flight data do not see nor my city. Even with all the zoom.

I found my city and my home. I typed my city "go to place:"

But it was a red line that I think goes through my contry.

This red line is normal?

After I located my city in Flightdata, it was easu to find my home. The red line lo longer appears indicantig another latitude and longitude away from where I am. (less a problem)

Now

When I put in (INS3) the mag is always red. Even after calibrating.

My GPS is OP_GPS. It has right side to put in the quad? minimum distance? The cable it is very short.
The OP_GPS good?
