Overview
The Atlas FMU is based on the open source Pixhawk FMUV6X standard, and is compatible with the PX4 autopilot software. With the same hardware, Atlas can run Allocortech’s SDK, enabling highly customized flight control solutions.
With a wide variety of interfaces including RS232, RS422, CAN, Ethernet, PWM, and more, Atlas is able to integrate into a wide variety of systems and perform flight
and payload management.
Atlas’ mission computer is a Toradex Verdin System on Module (SoM) and runs Linux. It is able to execute more strenuous software than the FMU but does not interrupt the FMU’s autopilot processor with lower priority or less time sensitive tasks. This can include mission planning, communication with a ground station, payload management, and more.
