Honeywell Aerospace, Cambridge

COM DEV International was a satellite technology, space sciences, and telecommunications company based in Cambridge, Ontario, Canada. The company had branches and offices in Ottawa, the United States, the United Kingdom, China and India.

COM DEV developed and manufactured specialized satellite systems, including microwave systems, switches, optical systems, specialized satellite antennas, as well as components for the aviation and aerospace industry. COM DEV also produced custom equipment designs for commercial, military and civilian purposes, as well as providing contract research for the space sciences.

History
COM DEV International was founded in 1974 and specialized in microwave technology for the aviation and aerospace industry. The company would go on to become a leader in space satellite componentry and hardware, specializing in telecommunication systems; a global designer and builder of telecommunication components and systems for space satellites; as well as one of Canada's largest sources of spacecraft instrumentation.

In 2001, its space products division opened an approximate $7-million Surface Acoustic Wave (SAW) development and manufacturing laboratory in its Cambridge facility.

In 2005, it purchased the EMS Technologies Space Science optical division in Ottawa, formerly CAL Corporation, from MacDonald, Dettwiler and Associates for $5 million.

In 2007, it purchased a Passive Microwave division in El Segundo, California, for $8.75 million. In 2010 it purchased Ottawa-based space instrument supplier Routes AstroEngineering for $1.7 million. Later that year, it established a subsidiary called exactEarth offering global ship tracking data services. In 2015, it purchased MESL Microwave of Edinburgh, Scotland. Also that year, it entered the waveguide market with the purchase of Pacific Wave Systems (PWS) of Garden Grove, California.

On November 15, 2015, Honeywell announced that it would acquire COM DEV, which would become part of Honeywell's Defense and Space business. On February 4, 2016, Honeywell announced that it had completed the acquisition, and COM DEV has since been renamed Honeywell Cambridge.
