Finally got the GoPro in the air! - Next up APM

Posted by Eduardo Romero on January 13, 2013 at 7:00pm

Here is some cool footage taken from that flight! 

 

 

Soon I will implement an APM that will hopefully help me calibrate HF radar antennas. HF radars are used to measure ocean surface currents in real time. Check it out!

    It fly great with the APM and I have been tempted to buy another when I can free up some more funds. Good luck.

    @Joseph Wow! Sorry for your loss and thanks for the advice. I do like how she glides trough the sky.

    I hope you changed out the stock pushrods for the tail. I had my elevator rod bend on me and caused my Super skysurfer nose dive. But I will tell you this... It is a very stable plane.

    Got it. Great application, have fun man.

    Calibrations work best if the signal travels at a moderate constant speed and distance. Pretty much a drone going in a big full circle from the site. ( this is where the apm would come in handy).

    To put it simply, each station transmits at a certain frequency and listens for the echo that is bounced back from a wave to determine velocities.  Kinda like a big radar gun pointing at the ocean. Interference is a big problem with these systems. By transmitting a known frequency (13mhz) and logging the known position of the drone, one can properly calibrate the antennas to help identify interference in the data.

    How will you use your drone to calibrate the antennas? Looking at the station positions on that map, it looks like a nice place to be working!

    It's going to be about -11F tonight where I'm at : (

    Pretty much...youtube video stabilization  has improved considerably in the past few months.

  • Joshua Ott January 13, 2013 at 9:40pm

    It looks like it has tilt stabilization, because the the nose of the plane seems to be moving relative to the camera. Is that just youtube panning and scanning? I've never tried their video stabilization.

  • Eduardo Romero January 13, 2013 at 9:35pm

    None, its just good old video stabilization provided by YouTube.
