What Antwerp Space does

Antwerp Space is a Belgian space engineering company that designs, integrates, tests and delivers space-qualified RF (radio-frequency) communication, navigation and radio-science subsystems for institutional and commercial space missions. The company's predecessor activity dates to 1962; today it is a wholly-owned subsidiary of OHB SE, a publicly-quoted European Space and Technology group employing more than 3,000 people. Antwerp Space operates from two Belgian sites — the head office in Antwerp-Hoboken (Berkenrodelei 33) and a regional office in Leuven — staffed by a team of highly skilled engineers and PhDs, and is positioned as a leading Belgian specialist in space-based RF applications.

The product portfolio is organized across four technology domains: communication subsystems for deep space, GEO, MEO and LEO missions (including the modular SWaP-optimized TT&C Transponder family and the ARGO reconfigurable data-relay satellite modem capable of 300 Mbit/s, selected by MDA Corporation and flown on the ISS via the European Data Relay Satellite System); navigation (Galileo Full Operational Capability Test User Receivers for the Public Regulated Service, integrated PNT payloads for small satellites, and field PRS end-user receivers under development); radio-science instruments (notably the Lander Radioscience / LaRa instrument, the first Belgian-made scientific instrument to land on another celestial body); and Radio Frequency Interference mitigation / SIGINT technology. Underpinning these products are five core technical competences — High Frequency Design, Digital Signal Processing, Software Defined Radio (SDR), Photonics, and general space-engineering know-how — with the flight-qualified SDR platform enabling in-flight reconfigurability serving as a key architectural differentiator. Antwerp Space's subsystems have flown on ESA's ExoMars 2022 and JUICE missions, and are in active development for Ariel, Vigil and the Galileo FOC TUR-P programme.

Revenue is generated primarily through long-cycle, multi-year development contracts awarded by the European Space Agency, EU bodies and national programmes, plus bespoke commercial deliveries as a specialist subcontractor to European satellite primes such as Airbus Defence and Space, Thales Alenia Space and MDA Corporation. The go-to-market motion is enterprise/B2G field sales complemented by presence at European space-industry conferences (IAC, ICSO, EPIC, International TT&C Workshop). Pricing is quote-based and not publicly disclosed. Revenue visibility is therefore tied to the cadence of ESA work plans and the mission selection processes of prime contractors, with a small number of institutional and prime accounts driving the majority of contract flow.

Core offering

Antwerp Space designs, develops, integrates, tests and delivers space-qualified RF communication, navigation and radio-science subsystems and instruments for satellite missions. Its portfolio covers Communication Subsystems (TT&C transponders, ARGO reconfigurable data relay modem, intersatellite link transceivers) for deep space, GEO, MEO and LEO missions; Galileo Public Regulated Service (PRS) receivers and PNT payloads; radio-science instruments such as the Lander Radioscience (LaRa); and Radio Frequency Interference / SIGINT technology. Products are typically delivered as integrated ensembles to institutional customers (ESA, EU bodies) and to European space primes (Airbus Defence and Space, Thales Alenia Space, MDA Corporation).

Product overview

Antwerp Space delivers a portfolio of space-based RF (radio-frequency) hardware products and integrated subsystems rather than a single unified software platform. Its offering is organized across four technology domains: (1) Communication Subsystems for deep-space, GEO, MEO, LEO and inter-satellite missions — anchored by the TT&C Transponder family and the ARGO Reconfigurable Data Relay Satellite Modem; (2) Navigation — anchored by the Galileo FOC TUR-P receivers and field PRS end-user receiver/security module for secure GNSS; (3) Radio-Science instruments and missions — including the LaRa Lander Radioscience instrument; and (4) Radio Frequency Interference & SIGINT — for RFI detection and mitigation. The portfolio is built on five in-house core competences: High Frequency Design, Digital Signal Processing, Software Defined Radio, Photonics, and general technical space competences, which underpin both the flight hardware and its in-flight reconfigurability. Products are typically delivered as mission-specific Communication Subsystems (e.g., for ExoMars 2022, JUICE, Ariel, Vigil) rather than as a single turnkey SaaS product.
