AttoPilot V3.0 6DOF IMU Q&A - Page 4

TeKrunner,

sorry I did not respond earlier but I have been out of town. The DEM information is used in mission simulation to warn you that you are to close to terrain (If i remember correctly you set what you want the limit to be). During flight it will also warn you that you are getting to close to terrain.

Hey Cort,
Thanks for that info, I found it quite interesting.

What's the scheme on the antenna tracker? ImmersionRC from the FPV forum sells one but it requires calibration everytime you move the antenna and you have to have their OSD device inside the plane. Can you elaborate on yours?

Well, think about if for a minute. If you move the antenna, how would it know where North is? Or where you moved the antenna to? The EzAntennaTracker Pro will have a built in GPS (required for self calibration) and a few other handy features so it can be used on a moving object and still track the plane/UAV.

Cheers,

Sander.

Sander is correct, unless you have a GPS on the tracker you will always need to point the tracker north to calibrate.

Can you PM more information on the pro tracker? Any idea when it'll be available?

Sure, or I can just post it here.

The tracking system is currently set up for Atto but we have provisions to make it work with other autopilots as well.

It is capable of moving 50kg although that is crazy overkill. Our system weighs 25lbs with counterweights. The extra ability is to withstand high wind loadings.

The tripod is a professional system with a single handed air assisted pole that can be raised and lowered to a height of 3m.

Availability is almost immediately although there is at least a 2 week lead time due to ordering of parts.

The price has not been set and is dependent of the components you choose for video and telemetry and the pan tilt gimbal you decide to go with. There are two options.

It is not cheap!!!!! It’s professional.

It may be a bit pre-mature just yet but if its an absolute necessity in a very short time we can chat about the time restraints you may have via e-mail or phone.

Thank you,

Chris

Correction: It would need a built in megnetometer t have any ide of North. The only thing you'll gain from having a GPS on the tracker station is that the tracker can be moved and because it knows where it is, there is enough information for the trig. You would still need to rotate the tracker to point it at the UAV as a one-time calibration per setup location, that is without a magnetometer in the tracker.

Got ya! Thanks for the clarification.

If you have to calibrate it by pointing it to the aircraft why does it have to set down pointing North.

I set my tracker down and point in the general area I'll fly, it turns left and right 200 degrees. I adjust a pot that tells the tracker where north is. I basically just use that as the one time calibration by adjusting it to point to the aircraft.

What is the IMU unit finally going to look like in terms of payload and control surface controls?

I remember there was going to be a daughter board with support for X many extra servos.

Also, the included GCS will be same as the one included with the 1.8V? or is the new one "professional" included with the IMU.

Dean is finalizing everything on the design. It will be a control unit and a separate IMU cube you can install anywhere. The first reason for this is we want you to be able to mount the IMU out of the way of wires and payload. Second reason is to give you the ability to buy just the IMU and integrate it into their own system. Third is in case you need to replace the IMU and do not want to dismantle your wiring in the bird. Plugging everything in and cleaning it up can be tedious.

The current GCS is the one that will be offered with the IMU. The "professional" version will be sold as a separate product if one needs.

will the control unit (support for how many controls) be purchase separately or included with the IMU.

I think you guys hit the nail on the head with ATTO 3.XX by separating both. Great idea!

Please update us with a tentative release month and a ball park price if available. I already have saved the $2500 for it.

I will talk to Dean on how many control outputs it has. I have a prototype and I do not want to make the wrong statement. There will be an expander board available.

I will also talk with the guys so we can finalize a price. It would be fair to say it will be around the $3000.00 USD range.
The control board comes with the system when you buy a full Autopilot.
