UAV Communication Protocol & Technology Matrices
Transcript of UAV Communication Protocol & Technology Matrices
Matrices ECE4007L01 About STANAG 4586 STANAG 4586 STANAG Edition 2 Ratification Draft was released to the public in 2011. Available http://www.innuvativesystems.com/STANAG4586Eed02a2_PubliclyReleased.pdf
STANAG Edition 3 is allegedly scheduled to be open source. *Source www.innuvativesystems.com. Edition 3 is complete and in the midst of ratification
There is not yet a governing body that certifies STANAG 4586 compliance for UAV systems. Source: CDL Systems http://www.cdlsystems.com/index.php/stanag4586 Benefits MAVLink Open source - available for free. MAVLink is LGPL licensed and can therefore be used as a library royalty-free in closed-source and open-source applications.
Supported by open source base stations (QGroundControl, APM Mission Planner) and open source autopilot systems (Ardupilot, PXHAWK).

Under review... Under review Under review MAVLink is a lightweight, header-only message marshalling library for micro air vehicles. About
MAVLink MAVLink has been shown to work on multiple microcontrollers and operating systems, including ARM7, ATMega, dsPic, STM32 and Windows, Linux and MacOS. MAVLink is extensively tested on the PIXHAWK, SLUGS and ArduPilotMega platforms and serves there as communication backbone for the MCU/IMU communication as well as for Linux interprocess and ground link communication. Only 8 bytes of overhead required per packet. Challenges Limited community support because it is only used by proprietary commercial autopilots (PICCOLO, MicroPilot) and by US Military and Allies
Software Development Kit (SDK) only available from Instrument Control for $5,200. Available at http://www.instrumentcontrol.se/products/nato
Implementing the protocol without the SDK would take a team of computer scientists months to complete. Innuvative Systems scientists teamed with Micropilot to integrate MicroPilot Autopilot into STANAG 4586-compliant 4CE Control Station. The project took 6 months.
