Celestial Space Technologies

Celestial Space Technologies is a space technology company specializing in the design and manufacture of high-performance satellite antennas optimized for small satellites. The company offers a streamlined three-step process — design, qualification, and delivery — to deliver highly reliable antenna solutions customized for each mission's specific requirements.

Celestial's antenna products are built around a philosophy of better, smaller, and lighter designs that deliver 3x the performance compared to conventional competing solutions, while maintaining low cost and short lead development times. All products support easy integration into standard CubeSat and small satellite form factors.

The company's product lineup includes S-band patch antennas for TT&C and data links in the 2.05–2.30 GHz range, and X-band patch antennas for high-throughput data downlink in the 7.00–8.50 GHz range. Both antenna types feature broad view angles for non-steerable satellite applications.

Beyond hardware, Celestial Space Technologies offers link budget design and estimation training and small satellite antenna education services, supporting the growing community of CubeSat developers and operators.
