Positioning

CesiumAstro is a US maker of active phased-array communications (antennas, beamforming, and processing integrated into flight-ready terminals) supplying the SDA Proliferated Warfighter architecture, with multi-orbit and 5G NTN product lines. It deepened vertical integration by acquiring RF-chip designer Jariet Technologies (August 2026), owning the silicon under its arrays, and raised $626M total (a $270M Series C in February 2026), though its platform-level Element demo has not yet flown. Revenue is estimated at 10-100m and hinges on the 2025-27 launch schedule.

Darker bar: ahead of the other company on that measure.

Positioning

Honeywell Aerospace is a publicly listed U.S. aerospace and defense supplier whose space activity centers on flight-proven avionics, inertial navigation, radiation-hardened electronics, reaction-wheel assemblies, optical payloads and quantum-secure satellite communications. Its space ecosystem includes NASA, ESA, Redwire, Colt Technology Services, Nokia, Quantum Brilliance and Jagiellonian University; the company completed its separation from Honeywell Technologies on Jun-29-26 and began trading as HONA. The distinguishing point is deep installed space heritage and high-tier institutional reach, while standalone space revenue and the scale of its satellite-connectivity deployments remain undisclosed.
