I stumbled upon this and thought others may think it's interesting as well...



Who knew the SP guys had competitions where they race around a triangle pattern of GPS coordinates? View results on Google Earth, get addional details from the plane to the ground station... Lots more.

Sounds fun but it's a little pricey.



The equipment seems like it would be very easy to adapt to UAVs...

    Yea... Palm, PocketPC, and one of those little Toshiba min-palmtop computers that runs Win98... If I just had something to do with them...

    Hey Brian , finally you found some use for those box full of palms :)).
    @ Marc, thanks , the code will surely be appreciated.. kindly post them once you have tested with small wiki if possible.. Thanks for sharing.
    @ Michael, thanks for the info , do you have any confirmed lead on the freq? 433 MHz is not exactly HF which is where confusion started( mine), 433MHz makes sense.

    Marc, that's cool. I've clenched onto my palm m105 for years waiting for something to do with it... They are POS 3.51.. Also have a PocketPC...
  • I wrote a PocketPC interface for a cheap chinese radio but most find the PocketPC's are too hard to see in direct sunlight, someone also wrote a Palm version and it is easier to read but with lower resolution. I'm finishing up a ground station for the Palm this week and will post code,files etc. when done. I'm using a Palm Vx TTL/RS232 level shifter, LiPo, and Xbee. The software is written using HandHeld basic, they have a free version. I've got a small bracket that attaches the Palm to my radio so I always have it near, and using the prototype for flight testing has been easier than using a laptop when I'm fly solo. The touch screen makes for a nice interface. Any Palm running OS 3.5 or higher will work but you'll need to build your own cable, and your model needs to have a serial port. I prefer using the older models like V Vx as they are easy to come by on eBay for cheap$.
  • They don't exactly say which RF module is used between the plane and the ground station, but it is a 433 Mhz ISM type transmitter, with channel selection.

    Bluetooth link from ipaq (or smartphone) to the ground radio... Still can't find details on "HF" module.
  • 'these RC guys' - and they would be who exactly?
  • Admin
    looks like it from size of antenna but it is no HF ;)
    only FCC ID T9JRN41-1 in pic reveals interesting blue tooth for GCS info may be I got the FCC ID wrong :(

    I couldn't find that info, I suspect 900mhz.

    & it is dev 5 years back!! Any idea on HF telemetry module!!? , what freq do they mean by HF and how did they manage to get away if real HF freq ( <30 Mhz) is used?
