Airborne navigation nacelle

Abstract

The invention relates to an airborne navigation nacelle which is used for providing enemy destination parameters to a main control room and comprises an inner ring platform, an outer ring frame and a base, wherein, the inner ring platform is hinged with the outer ring frame through a rotating shaft; the outer ring frame is hinged with the base through a hinge shaft; the base is fixed at the bottom of an airplane; a visible light television imaging system and a laser rangefinder are arranged inside the inner ring platform; the inner ring platform comprises a two-degree-of-freedom gyroscope, accelerometers, an imaging device, the laser rangefinder and a double-channel rotary transforming angle transducer; in addition, the outer ring frame comprises the double-channel rotary transforming angle transducer; a micromachining gyroscope is arranged on the base in the ordinate axis direction of an unmanned plane, measures the three-axis attitude of a carrier, and offsets the correlative navigation errors. Air speedometers are arranged in the ordinate axis direction and the pitch axis direction of the unmanned plane; an altimeter is arranged at the bottom of the base so as to measure the height of the unmanned plane; and the accelerometers are arranged at the two ends of the base so as to achieve levelling when in initial alignment. The airborne navigation nacelle can integrally detect, search and track a target, and has the advantages of high system reliability and low cost.

Description

technical field [0001] The invention relates to an airborne navigation pod, which is used for providing parameters of enemy targets to a main control room. Background technique [0002] In modern high-tech warfare, with the development of missile technology, the combat radius of ship missiles has increased, and the sea battlefield has become wider. Over-the-horizon attack operations have become the main combat style of surface ship anti-ship warfare. The so-called over-the-horizon attack refers to a missile attack on a target beyond the over-the-horizon of the shipboard radar by using a special long-range target indication system to provide target indication. The premise of realizing the over-the-horizon missile attack on the sea is that the anti-ship missile weapon platform must first locate the target over-the-horizon. The methods to realize over-the-horizon positioning mainly include relay station positioning, extended platform navigation coordinate positioning method an...

Problems solved by technology

From the perspective of positioning accuracy, although the accuracy of the extended platform navigation coordinate positioning method is higher than other types, the GPS navigation information that needs to be used is provided by the United States, so its reliability is restricted in extraordinary times
