Sparrow-Strike is an ultra-small-form-factor (USFF) MIL-SPEC rugged edge mission computer. Designed using a Modular Open Systems Approach (MOSA) with a modular chassis and architecture design, integrating either the NVIDIA Jetson Orin NX edge AI system on module (SOM) or an Intel x86-based processor, Sparrow-Strike provides the performance and flexibility demanded by emerging autonomous and uncrewed missions, in an ultra-compact and lightweight form factor. Sparrow-Strike is engineered to withstand austere environments and is SWaP-optimized for integration and deployment in highly space-constrained platforms.
