About Icarus
Where is Icarus headquartered?
Icarus is headquartered in Los Angeles, CA.
What does Icarus do?
Stratospheric birds for defense
What problem does Icarus solve?
Space-based sensing forces a tradeoff between quantity, quality, and timeliness of data, with vulnerable communications, limited information, and expensive, inflexible platforms.
What's Icarus's solution?
Icarus is building APOLLO, a solar-powered autonomous stratospheric aircraft flying above 60,000 feet for weeks at a time to provide continuous coverage and low-latency data and communications.
What makes Icarus different?
They cite specific comparisons to low Earth orbit satellites: 5-10ms fiber-like latency versus 25-60ms, persistent 24/7 fixed coverage versus intermittent ~10-minute orbit passes, and direct-to-device high-bandwidth comms without a satellite terminal.
What makes Icarus notable?
Founded by Henry Kwan, an aerospace engineer from Georgia Tech who previously worked on drones at NASA and on satellites at Orbital before starting the company, which has grown to about 50 employees.
