  • POINT2

    Programmed automatic flight.

    Programmed automatic flight is available by GNAS SKY CORE flight control program. Flight just as you imagined is achieved by diverse settings.
    Programmed automatic flight.
  • POINT3

    Resistant to wind.

    With its overwhelming strength achieved against strong and gusty wind compared with conventional drone, it will never get unstable even during descending. Capable of stable flight even under a wind speed exceeding 15 m/s.
    Resistant to wind.
  • POINT4

    A wide variety of options.

    Mounted GNAS SKY CORE automatically detects even unexpected obstacles. Achieve stable flight while reducing collision damage during automatic flight.
    Secured obstacle detection capability
  • POINT5

    Get to the site fast.

    It can cruise at up to 72 km/h. Arrive at the scene as soon as possible and complete your mission.
    Easy payload
  • POINT6

    Pilot assisting function.

    Based on information of a ground altitude sensor mounted on the body, it improves safety of flight by supporting the pilot in various situations.
     ・Speed control at a low altitude
     ・Minimum altitude holding function*
     *This function can be kept OFF.
