Direct peers

• ND SatCom: German provider of satellite ground stations, VSAT networks, and satcom infrastructure for defence, government, and broadcast. Comparable regional peer to Celestia Antwerp's turnkey ground-station business.
• Gilat Satellite Networks: Israeli specialist in VSAT ground terminals, satellite hubs, and ground-segment networks. Comparable to Celestia in ground-segment equipment for satellite broadband, with particular overlap in LEO/constellation gateway products.
• Hanwha Phasor: UK-based developer of active electronically steered phased array antennas for satellite communications. Direct technology peer to Celestia UK's eScan Ka-band phased array, both targeting LEO constellation gateways and satcom-on-the-move.
• Kratos Defense & Security Solutions: US-listed provider of space-domain awareness products, RF and microwave components, and satellite ground systems. Closely comparable to Celestia's HSTR space-debris radar, RF products, and ground-segment technology for defence and government customers.
• Tesat-Spacecom: German manufacturer of satellite communications equipment including RF subsystems, travelling wave tube amplifiers, and optical terminals. Directly comparable to Celestia TTI in space-qualified RF power amplification and payload equipment.
• Comtech Telecommunications: US-based supplier of satellite ground equipment including modems, SSPAs, and tracking antennas. Directly comparable to Celestia's baseband modems, GaN SSPAs, and electronically steered antennas serving defence and commercial satcom markets.
• Baylin Technologies (formerly Advantech Wireless): Canadian manufacturer of RF and satcom products including GaN SSPAs, BUCs, and antennas. Closely comparable to Celestia TTI's GaN SSPA portfolio across broadcast, defence, and satcom markets.

Broad incumbents

• Thales Alenia Space: Joint venture between Thales and Leonardo building spacecraft, orbital systems, and ground-segment infrastructure. Directly comparable because it offers ground stations, satcom equipment, and cryogenic/RF technology that overlaps Celestia's product portfolio, but at much larger scale and as part of a broader space prime offering.
• L3Harris Technologies: US defence prime with significant RF, satcom, and space-domain-awareness capabilities. Comparable to Celestia in space electronics and ground systems; new Celestia CEO George Gardner previously led L3Harris' Release & Integrated Solutions business unit.
• Airbus Defence and Space: European space prime manufacturing satellites, ground systems, and secure communications. Overlaps with Celestia across satellite payloads, ground infrastructure, and secure satcom (e.g., SpainSat NG alongside Hisdesat customer), but as part of a much broader aerospace and defence portfolio.
