Tracking lost aircraft

Postby JohanMoelich » Thu Aug 30, 2012 9:09 am

There are several tracking devices on the market. One option is a GPS tracker using a sim card to send out location details.
Another option is an RF beacon which works on UHF. FMKit makes one. The problem with this tracker is that it will probably interfere with UHF radios.

Something I need to check on, is tracking capabilities of the EZUHF radio modules, which I use. I know their receivers are also sending telemetry data back to the Tx (RSSI for starters). It might be possible to use this in some way. I'll be back with more info later. :hmmm:

If I remember correctly the ImmersionRC RX and OSD can send telemetry(SAT Co-ordinates) back on the left Audio channel.

Here's the FMKit option for $50 and it's super small. You just need a cheapie two-way radio to use it. It will probably not work when you use UHF for control.

After more reading about the FMKit option, I see they have a VOX version which only starts transmitting once it can't pick up motor and wind noise anymore (in other words, when the plane is on the ground). It uses a microphone to listen for noise or the lack of. Clever!

That's right, but I think you need to use their EZOSD and their Telemetry unit on the ground for this. I prefer using my own choice of OSD, and keep groundstation equipment to a minimum.

I rate that cheap gsm tracker would probably work for aircraft recovery.

Pot the thing in silicone to prevent it self destructing during a crash. Then SMS it and get the location sent to you.

I know there are other options, but this one seems the cheapest and easiest. As soon as I have a spare 400 bucks, Ill try it and let everyone know the result :)

I wonder how small and light it would be if you take it out of the case. Then do the silicone/hot glue thing and wrap it in foam or something.
You're right, it's probably the best option for lost aircraft. Nothing like a set of GPS coords to lead you directly to the crash site.

Its total weight is 50g. without a case probably 20-30g.
With strategically placed silicone, i cant see it weighing it at more than 40g.
So nothing to worry about.

Maybe you can also replace the Li-Ion battery with a single cell Lipo, which should also save some weight and will be easier to fast charge.

Hey scanman, look what I found! An open source tracking server which supports the TK102 device and others. :woot:
Is this what you were thinking of?
