Horizon31 PixC4-Jetson

../_images/horizon31_pixc4-jetson.png

The PixC4-Jetson is a professional-quality and NDAA Compliant Flight Management Unit (FMU), powerful single board computer and peripheral support system (USB, MIPI, Ethernet, M.2 slot, etc.) in a small form factor, designed to be integrated into end-user platforms. The term “PixC4” is derived from the Pixhawk, on which the FMU design is based (FMUv5) and C4, representing Command, Control, Compute and Communication.

Available as a turnkey solution including software pre-flashed on the Nvidia Jetson companion computer to enable the following features:

  • UDP Unicast/Multicast/Broadcast Telemetry (MAVLink)
  • LTE connection management with Layer-2 peer to peer VPN
  • Powerful multi-endpoint video encoding pipelines with example/open-source scripts for customization
  • ATAK Integration
  • Web interface for configuration and remote terminal access
  • Supports multiple simultaneous communication pathways such as LOS, LTE and Satcom with advanced stale command rejection and message deduplication
  • Scalable and secure cloud connectivity to Horizon31’s US servers and optional access to their cloud GCS and low-latency webRTC video distribution system (https://gcs.horizon31.com)
