What Cassiopeia Space Systems, Inc does

Cassiopeia Space Systems, Inc. (CSS) is a Virginia Beach, Virginia-based satellite communications (SATCOM) hardware company established in 2021 through the merger of Over-Sat and MIL-SAT LLC. The company designs and sells ultra-compact, multi-orbit (LEO/MEO/GEO) and multi-band (Ku/Ka-band) SATCOM terminal systems for maritime, aerospace, and land mobile/fixed applications, serving both defense/government and commercial customers globally. Its product portfolio comprises three core terminal families — RIGEL (multi-orbit terminal for maritime, airborne, COTM, and ground stations), MANTIS (high-performance low-SWaP terminals for tactical, airborne, and mobile platforms, available in MANTIS-10 and MANTIS-6 variants), and PYTHON (lightweight Ka-band terminal for mission-critical LEO/GEO connectivity) — all built around a proprietary 3D-printed Luneburg Lens antenna architecture integrated with precision stabilized tracking platforms. The lens-based design enables electronic beam steering without mechanical movement, supporting seamless satellite handover across LEO constellations and installation on small or uncrewed platforms (UAVs, USVs, AUVs, ground vehicles) where traditional parabolic or phased-array antennas cannot fit.

Cassiopeia's go-to-market is a direct enterprise field-sales motion supplemented by trade-show presence at industry events such as the Satellite 2022, 2023, and 2026 conferences (Booth 1436 in 2026) and the US-Israel Space Tech Event. The company generates revenue primarily through hardware sales of SATCOM terminal systems to defense agencies, government contractors, and commercial maritime and aerospace enterprises under quote-based, B2B/B2G contracts, with pricing not publicly disclosed. Marketing channels include the company website (cassiopeia-space.com), LinkedIn, and earned media coverage in Satellite Today (Via Satellite) and Mil-Sat Magazine.

The company is majority U.S.-owned and privately held, with Worldwide Adventures Inc. serving as the parent entity of the legacy MIL-SAT subsidiary. Leadership includes Don Richardson (Chairman & CEO), Joe Conboy (CEO), Yossi Levy (President, former Israeli Navy flag officer), Jennifer Minyard (COO), Yosi Albagli (CTO, former VocalTec CEO), and John Beahm (CFO), with board members Sean McDaniel (founder of ATLAS Space Operations) and Lior Weinstein (former Over-Sat CEO). The company has no disclosed funding rounds, reported revenue figures, or named customer wins in the available source data, and currently reports a headcount of approximately 5 employees. It received the BIRD (Binational Industrial Research and Development) Award in 2021 recognizing innovative SATCOM technology development.

• Honeywell Aerospace: Honeywell's JetWave and other SATCOM systems serve commercial aviation and defense connectivity. A broad incumbent competing in the airborne and defense SATCOM terminal space where Cassiopeia's MANTIS plays.
• Cobham Satcom (Thales): Cobham (now part of Thales) supplies aviation, maritime, and land SATCOM terminals for commercial and defense markets. Larger incumbent with a broader portfolio, but directly competes in maritime SATCOM antennas.
• Raytheon (RTX): RTX/Raytheon produces defense SATCOM terminals, multi-orbit ground and user-segment systems, and is a prime on major DoD communications programs. Broad incumbent addressing defense markets where Cassiopeia pursues RIGEL/MANTIS business.

Others

• ATLAS Space Operations: ATLAS operates a global ground-station network and satellite-to-ground communications management. Not a direct terminal peer, but a fellow SATCOM ecosystem participant whose founder (Sean McDaniel) sits on Cassiopeia's board, indicating a strategic relationship.
