    To anybody who is interested I recently added a laser altimeter to my old radian gimbal for my work. We take Balcony shots of high rise buildings so we need something super accurate. I finally made it happen it reads to the cm!!
    parts used :
    fc: pixhawk fc

    laser: sf11/c

    osd: Alceosd 0v3
    http://www.satxo.com/shop/index.php?id_product=8&controller=product

    Its pretty well documented on how to set-up it does require some programming through the open source mission planner and cutting and soldering of wires.

    documents are here:

    thanks

    Bonus points for that, Jason. Have you been able to cross-correlate its accuracy?

    Andy yes I did! First test was tape measure gaffed taped to the wall holding it up at different heights then trying to read the fpv screen. (help is required lol). very accurate!

    I have used it on jobs vs a crane also its perfect just have to fly slow enough so my camera ops can take the photos at the correct height. :)

    Nice!

    It states that it's good for 120 meters.....just wondered if you happened to accidentally drift above that and notice whether it actually works (nudge, nudge, know what I mean, eh?) :rolleyes:

    I dont normally fly more than 100m have not had any jobs to fly that high and test it out. I need some big space to fly that high!

    Just a bit of an update I have now attached a shutter cable directly to the laser and can set of the shutter at exactly required height.

    If anybody takes Construction/Development Photography knows this is very important. So if you do this kind of work let me know i want the company to add more "trigger points"

    thanks
