ANPC

Advanced Navigation and Positioning Corporation, known as ANPC, is based in Hood River, Oregon. The company sits along the Columbia River, east of Portland. It supplies precision approach guidance and area surveillance systems for civil and military aviation.

The company's transponder-based systems are designed for airfields where other systems cannot be installed. The site says most airports cannot support existing systems because of terrain, obstacles and other challenges. The transponder landing system provides vertical and horizontal approach guidance for terrain-challenged airports.

The site says the transponder landing system can provide a CAT I precision approach where other installations are not feasible or cost effective. The local area multilateration system provides surveillance with no moving parts. The site says a small team can deploy it to full operation in less than two hours.

ANPC also makes transportable systems for temporary or remote airfields. The site says these are used for defense, security and disaster recovery work. The systems can be moved by land, air or sea. The site says the company has customers on all seven continents.

The company traces its roots to 1991, when its founders developed the transponder landing system. The site calls ANPC a transponder multilateration pioneer. The system combines time-of-arrival multilateration with phase measurement, and it can work with ILS airborne equipment. The surveillance parts were separated into the LAMS product line in 2009.

The site lists a board of directors, careers, news and a blog. The contact page gives a freephone number in the USA, 800 228 1857 extension 230, and a global number, +1 541 386 1747. The office is at 489 North 8th Street, Suite 203, Hood River, Oregon 97031.
