ComNav Engineering, Inc.

ComNav Engineering was established in 1991 and incorporated in the state of Maine in 1994 by Martin J. Geesaman. Initially the company operated as a sole proprietorship providing engineering consulting services to several microwave filter companies. During this period, a software program entitled Filtroid was developed to assist engineers in designing microwave filters.

ComNav Engineering, as a manufacturer, began as a product group of Control Devices, a GTE subsidiary. Martin Geesaman and Scott Burgess spent three years doing research and development of various coating techniques and ceramic filter typologies. The result was a superior coating technique that yields unparalleled unloaded Q and adhesion. This coating technique along with several proprietary filter typologies translate into the low loss high performance filter structures that are the corner stone of ComNav's product line today.

As the filter group began to expand and demand more resources, it became a distraction to the rest of Control Devices, whose primary focus is the automotive business. It was decided to spin off the filter group into a separate company. Mr. Geesaman acquired backing to purchase the assets, and folded the filter group into ComNav Engineering. ComNav Engineering began manufacturing operations in June of 1996 as an independent company, though we remain close friends and drinking buddies with Control Devices.
