[0005] The above-mentioned systems all adopt a structural design that separates photography and navigation, that is, the navigation system requires separate computer control, display and data management, which results in two computers working on the plane, which is not suitable for high-altitude large aircraft aerial photogrammetry platforms. Too much impact, but for small aircraft platforms flying at low altitudes, it will not only increase the load burden of the aircraft, but also affect the power consumption and endurance of the aircraft, especially for ultra-low altitude light aircraft with limited space. to stand out

Abstract
The invention provides an onboard GPS aerial photography navigation control system and a control method thereof. The system comprises an aviationGPS receiver, an aviationdigital camera, a display terminal and an onboard computer, wherein the aviationGPS receiver is used for capturing a GPS signal and generating and outputting GPS data for indicating the position of the system; the onboard computer is used for calculating navigation information for indicating position relationship among the system, an air line and a target point according to the position data of the air line and the target point as well as GPS data, displays the navigation information on the display terminal, navigates according to the navigation information and controls the aviation digital camera to expose while satisfying the exposure condition. The invention combines navigation and shooting control, reduces computation cost and lowers cost.
Description
technical field [0001] The invention relates to the field of navigation, in particular to an airborne GPS aerial photography navigation control system and a control method thereof. Background technique [0002] Airborne GPS (Global Positioning System, Global Positioning System) flight control technology is to realize flight special navigation through GPS high-precision positioning technology, especially for the navigation of various airborne aerial photography, airborne radar, loading laser and other aircraft platforms. Because the aircraft not only needs to fly according to a specific route, but also needs the task load to achieve the specified operation during the flight. Therefore, it is necessary to manage and control the flight and mission load of the aircraft in a unified manner, and coordinate all parts to complete the mission together. [0003] In the field of aerial photography, in order to ensure the overlapping degree of front and rear images, left and right imag...
