Automatic adjusting FPV receiver antenna

-

hello,

the project i'm trying realise automatic adjustment system patch antenna fpv drone.

there similar systems working gps tracking of drone, work need (expensive) gps module realise that.

so idea based on ndb communication using fpv transmitting waves adjust loop antenna adf does. here transmitter moving 1 , receiver on groundstation.

now comes tricky part:
the ndb works through mf anf lf, transmitter sends in uhf (5.8ghz). placing second ndb transmitter on drone not option due long antenna system has be.
the thing uhf antenna has short , don't know how realise making loopantannae receive proper signal transmitter.

is there chance make work uhf?
could high resolution achieved?

the big advantege see doing uhf faster setting time, can imagine there complications adjusting and/or receiving through loop antennae.

is posible build such antenna?

since i've never seen type of direction finding other in ndb's don't know if works higher frequencies.

i hope can me.

best regards
majorprob

the higher frequencies blocked smaller objects. reflect off pretty anything. fills in 'holes' behind objects. directional antenna see reflections coming everywhere.

look closer @ commercial systems. if find 1 doesn't use gps, concept practical , can see kind of antenna using. if there isn't one, suggests df isn't practical @ frequency. nothing's impossible, might take several thousand dollars worth of antenna , signal processing it.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
