MP2128HELI3
Description
MicroPilot’s MP2128HELI3 is the first autopilot to use the 3rd generation processor and software. The form factor, connectors, and I/O ports will remain the same as MicroPilot’s 2nd generation autopilots. This preserves compatibility and our customers’ investment into the platform.
With ARINC 653 partitioned RTOS certifiable up to DO-178C DAL A, the MP2128HELI3 autopilot is ready to meet the UAV industry’s safety requirements.
Features
- Based on proven MicroPilot autopilot technology, the MP2128HELI3 can fly multi-rotor, fixed-wing and helicopter
- Safety-critical microprocessor
- Software and form factor compatible with the MP2x28ᵍ² series of autopilots
- Error correcting RAM, Flash, and Cache protects against single bit upset
- Ethernet support for more flexible communication
- Improved gyros for a more accurate attitude estimate and better flight performance
- Upgraded GNSS receiver supports more constellations and increased reliability
- Improved temperature compensation increases airspeed accuracy
- Almost triple the onboard flash memory allows longer data logs
- Dual-core lock-step guarantees any processor errors are detected
- Error-checking I/O ensures data integrity among chips
- More serial ports with larger transmit and receive buffers supports higher baud rates
- Floating point coprocessor for faster arithmetic operations
- Does not use interrupts other than the on-chip timing interrupt
- ARINC 653 partitioned RTOS certifiable up to DO-178C DAL A
- Tripled processor speed accommodates tomorrow’s algorithms
ARINC-653 Partitioned Operating System
MicroPilot’s MP2128HELI3 is the only UAV autopilot to use an aerospace-grade partitioned operating system. Partitioning protects critical software from less critical software, improving reliability and simplifying certification.
