Navigation Aids

Ground Based Air Navigation

Ground Based Air Navigation systems or Navigation Aids, transmit signals that are used to calculate bearing and range of information to aid in pilot navigation.

Moog's history in Navigation Aids dates back to the 1960's.  Our product heritage is based on supplying innovative system solutions to the US Department of Defense.  By the 1980's, we were supplying complete shipboard, mobile and man portable TACAN systems to the US and its allies.

In 2009, Fernau Avionics Ltd. became part of Moog, bringing with it a highly talented workforce and broad range of navigation products for civil, military and marine applications.

The combined business is now able to offer customers a broad range of options to meet their unique needs, all backed by world-class customer support.
