Raytheon Technologies [RTX] on Monday said its United Kingdom-based subsidiary has agreed to acquire another U.K.-based company that specializes in space domain awareness.

Terms of the deal were not disclosed.

Northern Space and Security Ltd.

(NORSS) provides orbital analyst services to the U.K. Space Agency, including capabilities for government and U.K. satellite operators. NORSS also is developing a simulator for the U.K. Ministry of Defence used in the development and testing of future British military satellite systems and constellations.

“Bringing together the complementary capabilities of these two leading space companies will enhance the quality of the U.K.’s orbital analysis and space situational awareness technologies,” Jeff Lewis, chief executive of Raytheon UK, said in a statement. “It also answers a call made by the U.K. government for companies to invest in cutting-edge space technologies.”

Raytheon UK is part of Raytheon Intelligence & Space, an operating segment of Raytheon Technologies.

For NORSS, the pending deal will provide an entrée into new markets.

“The acquisition, upon completion, will facilitate expansion by NORSS through access into new markets,” Ralph “Dinz” Dinsley, the company’s executive director, said in a statement. “As part of Raytheon Intelligence & Space, we will have expanded access to international markets, continued investments in research and development, and opportunities to collaborate on the next generation of space technologies.”

Space domain awareness is becoming increasingly critical amid a proliferation of commercial and government satellites.
