Tacan Coverage and Channel Requirements

The Tacan radio air navigation aid has been adopted as a part of the common system of navigation in the United States. A study has been made of some of the problems involved in the implementation of the system. Predictions are made of the coverage to be expected in the air space surrounding a Tacan ground facility. The service to be expected in the presence of interfering Tacan signals is shown under various conditions. Channel requirements are indicated for implementation of the system in the continental United States.
