Neon67 Posted January 15, 2014 Posted January 15, 2014 AS an IT student , I was wondering, what kind of transmission does the drone use ? My guess is by sattelite, however what are the spec of such transmissions channel ? Cause a lot of data has to be transfered such as video in HD (specially for the next drone generation) and the drone avionics itself . I'm a little interrested about what kind of video compression they used and so on, the latency, max bandwith . Signal has to be cripted aswell, so it's even a heavier process burdening the drone computer Does anyone know ?

Neon67 Posted January 15, 2014 Author Posted January 15, 2014 most of it im sure, but i'm sure there are some infos here and there
Bushmanni Posted January 15, 2014 Posted January 15, 2014 There's a steerable satellite dish in the hump of the drone. Most likely it's bandwith is pretty much equivalent with comparable civilian tech. Steerable dishes like that are found in marine satellite communications systems. http://www.kvh.com/Military-and-Government/Maritime-Systems/Television.aspx DCS Finland: Suomalainen DCS yhteisö -- Finnish DCS community -------------------------------------------------- SF Squadron
johnsonscott Posted January 25, 2014 Posted January 25, 2014 (edited) of course they will use satelite for sending orders... Edited January 26, 2014 by johnsonscott www.hemorrhoid-miracles.com
Bucic Posted January 26, 2014 Posted January 26, 2014 Most drones nowadays are supposed to use NATO crypto communications and so the connection specifications, e.g. LINK 16, are described in respective STANAG standards, in detail. They even contain data words compositions down to specific bits and use of communication technologies like https://en.wikipedia.org/wiki/Frequency-hopping_spread_spectrum I'm sure the secret and top secret bits of the specifications are kept in separate documents so that lack of highest level clearence does not cut you off completely.

Scrim Posted February 12, 2014 Posted February 12, 2014 A well kept secret of the US Air Force is that drones are actually flown via two hand held pieces of string, one in each wing tip, and the camera is a handicam velcro'd to the belly of it.
