The KLN 90B is an extremely sophisticated navigational device, capable of providing highly accurate navigation over most parts of the world.
The KLN 90B panel mounted unit contains the GPS sensor, the navigation computer, a CRT display, and all controls required to operate the unit. It also houses the data base cartridge which plugs directly into the back of the unit.
A basic KLN 90B system consists of a panel mounted KLN 90B GPS sensor/navigation computer, a data base cartridge, and an antenna. An altitude input is required to obtain full navigation and operational capabilities. Additional system components may be added or interfaced to the KLN 90B which increase its features and capabilities.
