TACAN navigation automatic channel selection method

Abstract

The invention discloses a TACAN navigation automatic channel selection method, and aims to reduce the number of times of automatic channel selection and ensure the precision and continuity of TACAN navigation. The method is implemented through the following steps of: determining effective TACAN double-station geometric distribution for implementing TACAN double-station navigation; determining a TACAN navigation basic channel selection module according to the principles of distance search, included angle search and optimal included angle channel selection; and designing a strategy for reducing channel selection switching times based on an effective included angle change interval, calculating the distance and an included angle between an aircraft and the two selected TACAN channels, directly taking a channel selection result at the previous moment as the channel selection result at the current moment in the set effective included angle change interval, otherwise, if at least one of the distance value or the included angle value does not meet the condition, executing the basic channel selection module. By combining a basic channel selection module with the strategy for reducing channel selection switching times, and functions of data acquisition, data analysis, data processing and result display are realized, so that the optimized TACAN navigation automatic channel selection method is obtained.

Description

technical field [0001] The invention relates to an automatic channel selection method used in a control system of Tacan TACAN air navigation equipment. Background technique [0002] Tacan is a radio navigation and positioning system, which is composed of airborne equipment, Tacan beacons, beacon detection beacon simulators and Tacan indicating control equipment. Its operating distance is 200 nautical miles, and its working frequency band is 962-1213 MHz. It is a short-range polar coordinate radio navigation system. When the system is working, the ground beacon station receives the ranging inquiry signal from the airborne equipment and transmits the azimuth signal, the ranging answer signal and the beacon identification signal to its coverage area according to the specific technical requirements, so that the airborne equipment can perform position measurement. distance and identification. The Tacan beacon transmits radio signals to the active airspace in the form of a rotat...
