Engineering Tomorrow’s Systems

We build the infrastructure that lets operators trust unmanned systems at scale. That covers secure enrollment, key management, verifiable provenance and firmware updates for PX4 and Zephyr fleets.

Bespoke electronics and firmware development

Experience with bespoke electronics and firmware development for a variety of devices and platforms.

Autopilot platforms

  • PX4 Autopilot: Autopilot integration and customization—new drivers, parameterization, tuning workflows, and mission behavior for field deployment.
  • Pixhawk: Hardware bring-up and system integration—power, sensors, telemetry, companion compute, and robust wiring/EMI practices.

Sensors & drivers

  • Sensor integrations: End-to-end sensor bring-up—interfaces (I2C/SPI/UART/CAN), calibration, timing/sync, and validation in real operating conditions.
  • Custom drivers: Driver development and maintenance—clean abstractions, upstream-friendly structure, testability, and long-term support.

Security

  • HSM security: Secure key handling and signing flows—hardware-backed key storage, provisioning, rotation, and audit-friendly operational procedures.

Connectivity & radio

  • NB‑IoT: Cellular IoT integration—modem bring-up, power optimization, connectivity hardening, telemetry pipelines, and fleet troubleshooting.
  • LoRa: Long-range telemetry design—radio configuration, network/server integration, payload design, and range/reliability testing.
  • 5G: High-bandwidth comms integration—router/modem selection, antenna placement, link resilience, and secure edge connectivity.
  • DECT NR+: Private, resilient radio links—system design considerations, integration planning, and deployment support for constrained/contested environments.
