IQ Spacecom

IQ spacecom is a business unit of IQ Technologies for Earth and Space GmbH (formerly IQ wireless GmbH), a Berlin company established 25 years ago whose other division is IQ FireWatch. With more than 50 employees across the two units, the company develops radio communication systems for small satellites such as CubeSats, from a site at Ernst-Lau-Strasse 5 in Berlin-Adlershof. IQ spacecom is a member of the German Aerospace Industries Association (BDLI). Its XLink-S software defined radio transceiver flew aboard NASA's Artemis II mission, and its XLink transceivers supported Reflex Aerospace's SIGI satellite beyond its planned one-year operation.
