Sky-Drones.com unveils SmartAP 4 Autopilot - the latest generation flight control system for multirotor Unmanned Aerial Vehicles of various configurations and sizes aimed at the wide range of applications. The main feature of the system is the capability of fully autonomous flight including take off, waypoints flight, landing and much more. The core is based on powerful 32-bit microcontroller ST Microelectronics® STM32F4 and 9-axis Inertial Measurement Unit. The latest UBlox® GPS module with integrated 3-axis magnetometer and pressure sensor can be connected externally for autonomous flight capabilities as well as wireless telemetry module for system configuration, mission planning & control and in-flight monitoring via specially designed SmartAP Ground Control Station and Configuration Tool. SmartAP 4.x supports any type of multirotor UAV with outstanding flight performance, reliability, navigation and control precision. Compact size and weight makes integration of the system fast and easy, various I/O interfaces allow creating the applications for interaction with 3rd party electronics and payload.

Kirill, you are an impressive guy to create both software and hardware autopilot!

On what data do you claim it is more stable and more precise in navigation than ardupilot ? What about reliability of the code and hardware vs a Pixhawk with ardupilot?

Comment by Kirill on April 11, 2016 at 2:51am

Hugues, it's generally based on log files data as well as just visual side by side comparison. 

Reliability is higher due to lots of test-bench hardware and software simulations which helped to reveal and fix all possible issues even before the actual flying.

Do you have fixed wing capability as well.
Comment by UAS_Pilot on April 11, 2016 at 7:11am

Will this work on traditional helicopters too?

Kirill

It looks good. I think there is a market for the people that just want something that is more plug and play.

We do need to see it in the wild, obviously. Where are your major markets now? Russia? What is your current user base like? Will this tune itself for different platforms? Can you use RTK? Will it perform the same mapping functions as a Pixhawk?

You know, of course, that you are going to have to back-up claims of higher reliability and better performance with this crowd here. It is always great to see new options though, so best of luck in breaking out.

Dwgsparky, UAS_Pilot, No, not yet, fixed wing and traditional helicopter support is kept in mind but I can't say any exact time frames regarding this.

'Looking forward to the side-by-side comparisons!

Comment by Kirill on April 11, 2016 at 12:54pm

Marc, thanks! Yes, this is basically the main idea of the product, easy to set up, just plug and fly. 

Side by side comparison and more flight demos are coming soon. Russian market is not very big actually and it's quite difficult to work on it, so the majority of SmartAP users are in the US and Europe. Generally the system is used for aerial filming, photography and surveillance. Auto tuning is not really necessary since the flight performance is very good even with the default settings. RTK support is planned for the nearest future. Intelligent mapping interface is currently in development and will be released in the next version of SmartAP GCS. 
Yes, of course, the words will be backed-up soon, hope we'll be able to get attention of the community.

How much with flight control only?
