We engineer the physics between an idea and a fielded system.

Parhelia Technology develops novel computing hardware and the software that drives it — from custom arithmetic pipelines to the sensors and flight systems that depend on them. We move new computing paradigms from the bench to the mission, alongside research institutions, defense programs, and industry partners.

Parhelion (par·he·li·on) — a bright halo formed when sunlight bends through ice crystals suspended in the air. Our name is a reminder that the most useful physics is often the physics no one has bent to purpose yet.

Focus Areas

Four disciplines, one design loop

Each area below feeds the others — a sensor architecture informs the arithmetic pipeline that reads it, which informs the embedded platform that has to fly it. We work up and down that chain rather than handing off between them.

01 / COMPUTE

Computing Architectures

Custom arithmetic and computing elements designed alongside the software that runs on them, not after.

Hardware-software codesign Custom arithmetic pipelines Novel computing elements Analog computing Asynchronous operations Design libraries

02 / SENSE

Sensing & Signal Systems

Multi-band sensing across optical (visible, SWIR, LWIR) and RF (LoRa, burst, microwave), with compute built into the sensing element itself — picking out the salient signal at the source instead of shipping everything to the back end. Less data to move means less SWaP for the whole system.

03 / DEPLOY

Embedded & Flight Systems

High-performance compute under real constraints: size, weight, power, and the demands of flight-critical operation.

High performance embedded computing Low SWaP design Flight critical systems Avionics Autonomous vehicles

04 / ANALYZE

Security & Analysis

Understanding hardware as built, not just as designed — down to the sideband channels it wasn't meant to expose.

About Parhelia

From research bench to fielded mission

Parhelia Technology exists at the point where new physics meets old constraints. We build novel computing hardware embedded into the sensors themselves — melding analog and digital technologies — and pair it with the software and system design needed to make it highly efficient.

We partner across the ecosystem to bring new computing paradigms to fruition: academic research groups pushing the underlying science, defense programs that need it to work under real operational constraints, and commercial industry that needs it to work at cost.

That range shapes how we work. A technique that starts as a lab-bench result on prototype hardware can end up inside a low-SWaP embedded platform flying on an autonomous vehicle — and we stay involved through that whole path, not just the first or last step of it.
