Sky-Drones announces release of the next generation flight controller - SmartAP 3.2 Pro, the system became even more integrated, powerful and provides extensive set of features. It has 3x-redundant temperature-stabilized IMU, integrated OSD telemetry with power supply for camera / video TX, integrated long-range 500 mW telemetry module, FrSky S.Port telemetry support, RTK GNSS support (with additional SmartAP RTK extension), 10-60V (3-14S) power input and much more. SmartAP supports any type of multirotor UAV and provides the highest navigation and control precision. The main capabilities of the flight controller are: 

  • Outstanding flight stability in all modes - manual (user control), position hold (semi-autonomous control) and auto (fully autonomous navigation and control)
  • 3x-redundant temperature-stabilized IMU
  • Fully compatible with SmartAP GCS Ground Control Station for Configuration and Mission Planning
  • Integrated OSD (On-Screen Display for FPV) with camera / video TX power supply
  • Accurate GPS Position hold (up to 40cm with good GNSS reception quality)
  • Accurate Altitude hold (up to 10 cm)
  • Return to Home flight mode
  • Fully autonomous waypoints flight mode
  • Guided flight mode
  • Various failsafe events configuration and triggering

Temperature-stabilized IMU allows using the system in the wide range of temperatures (-40...+60) with no need of recalibrating.

Great work, do you support Fixed wings planes? We are using a Vtail fixed wings plane. 

Comment by Kirill on June 14, 2017 at 2:02pm

John, yes, it's currently in development.

Comment by davidbuzz on June 14, 2017 at 4:40pm

So, does it run ArduPilot or PX4?  

Comment by Marc Dornan on June 14, 2017 at 5:05pm
Neither. It is proprietary.
Comment by Marc Dornan on June 14, 2017 at 5:07pm
Kirin- when will the fixed wing support be available?

Comment by davidbuzz on June 14, 2017 at 8:03pm

> proprietary  
well, that's a shame.  it might have been interesting if it ran something open.

Comment by Marc Dornan on June 14, 2017 at 8:20pm

Kirill -- I realize Kirin is a Japanese beer. Typo!

David, as Marc mentioned it's running our proprietary firmware.
