The Alta X is designed to satisfy the needs of professional and industrial partners. Freefly designed
the ALTA X from the ground up to achieve the perfect blend of efficiency, agility, and reliability
while keeping the pilot workflow simple and fast. ALTA X builds on the experience and
lessons learned bringing ALTA 6 and 8 to the world.
— MADE IN THE USA | Designed, assembled, tested, and supported by Freefly in Woodinville, Washington, USA —
Alta ActiveBlade — The Alta ActiveBlade design reduces vibrations to 1/5th of the normal level. Reduced vibration means lower fatigue on components, longer motor bearing life, less payload vibration for cleaner data collection, and of course, better footage when utilizing the camera.
Expansion Ports and Integration — Alta X is built to carry just about anything with an integrated quick release system on top and bottom of the aircraft. The software stack is equally as flexible through the use of Auterion’s Enterprise PX4 and through supporting the MAVSDK. Alta X features 3 battery voltage power outputs and optional 5V, 12V DC to DC converters to power your payloads.
Auterion Enterprise PX4 — Auterion and Freefly jointly develop and improve PX4 firmware for use on Freefly drones. Control Alta with custom MAVSDK API software which can be used from the ground via radio, or onboard via an expansion computer (not included).
