What is UAV?

Unmanned Aerial Vehicle (UAV), also known as a drone, is an aircraft without a human pilot onboard. A key feature of UAV is its autonomy, meaning that no pilot intervention since take off required. The variety of UAV applications are mainly focused on aerial photography, videography and monitoring. Electronics and software make this possible - here comes SmartAP Autopilot.

What is SmartAP?

SmartAP Autopilot is the high-level flight control system for multirotor Unmanned Aerial Vehicles with the capability of fully autonomous flight including take off, waypoints flight and landing. The hardware core is powered by STM32F4 microcontroller from STMicroelectronics, 9-axis Inertial Measurement Unit and the latest GPS/GLONASS receiver from UBlox providing outstanding flight precision. SmartAP has its own Configuration and Mission Planning software called SmartAP GCS. The system supports any type of multirotor UAV with highest navigation and control accuracy. SmartAP Autopilot was developed using the latest electronic components available at the moment, which allowed us to achieve such amazing results!

SmartAP 4 Flight Control System (coming soon)

SmartAP 4 Autopilot is 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 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.
