About Streamline Systems
Summary
Streamline Systems builds a drop-in navigation module for UAVs that operates without satellite positioning. The module integrates with Ardupilot, INAV, and PX4 flight controllers, delivering centimetre-precision, EW-resistant autonomous flight where GPS is unavailable or unreliable. It replaces GPS as the primary positioning layer for both commercial and military drone operators.
Go-to-market
Commercial and military drone operators are the target customers, reached through a direct briefing-request flow on the company's website.
From the Y Combinator listing
Precision navigation for UAVs operating without GPS.
Streamline Systems is building the replacement for GPS. Satellite positioning has become the single point of failure for almost every modern system, both military and civil. We've built the replacement. A drop-in module that integrates with existing Ardupilot, INAV and PX4 flight controllers, with demonstrated satellite-independent autonomous flight and GPS handoff. We're currently working with commercial and military end users to deploy the capability.
