I assume that Bayraktar can operate 18.000/20.000 feet altitute with bomb payload (i take old flightradar24 data as basement of this claim), which is enough to avoid MANPADS and even low range vehicle-mounted air defense systems. Bayraktar can only operate 150-200km away from antennas, but you can put more antennas to cover more land inside of your country. Still, very limited usage potential in foreign airspace.
ANKA can fly at 30.000 feet, so it can avoid MANPADS threat, most of low/medium range air defense systems. It can also be operated far away from Turkish airspace via SatCom, where the satellite have cover.
Bayraktar is a perfect system to be used against terrorists inside of our country and/or close to our borders where less mountains exist.
ANKA can be operated in very mountainous areas including Northern Iraq, or even in deep Afghanistan geography. ANKA an even be used against Iraq-Syria kind armies where air defense is not very effective in all of their countries, since even most of the medium range air defense systems won't be able to hit ANKA.
