Multiple launchers can be launched at the same time, and after launching, they can be loaded on site and launched again. This method is flexible to deploy and low cost.

[0029] like Figure 1 As shown, the UAV 1 of Embodiment 1, Embodiment 2 and Embodiment 3 all include: a body platform 11, on which a fuel system module 12, an anti-interference satellite antenna module 13, an inertial navigation module 14, an airborne computer module 15, a servo device 16, a power unit 17 and an ammunition module 18 are arranged; the airborne computer module 15 is used for flight control, flight management, navigation management, and mission equipment control and management of the UAV 1; the servo device 16 is used to receive the control signal of the airborne computer module 15 and drive the rudder to deflect so as to control the flight of the UAV 1; the anti-interference satellite antenna module 13 is used to receive satellite signals from different satellites, and when one or more satellite signals are interfered with, the UAV 1 is combinedly positioned and navigated using the uninterrupted satellite signals; the inertial navigation module 14 is used to measure the heading, attitude, angular velocity, acceleration, speed and position parameter information of the UAV 1; and the ammunition module 18 is used to detonate the warhead to destroy the target.

[0030] Among them, the inertial navigation module 14 is also used to output positioning information when the satellite antenna positioning information is effectively used for combined navigation or pure inertial mode, and the anti-interference satellite antenna module 13 is also used to use the pure inertial mode for positioning and navigation when all satellite antennas fail.

[0031] The power device 1 includes a generator, an engine, and a propeller. The generator is used to provide power to the airborne equipment, and the engine drives the propeller to rotate to provide power for the UAV 1.

[0032] The anti-interference satellite antenna module 13 includes a Beidou satellite antenna, a GPS satellite antenna and a GLONASS satellite antenna.

[0033] Secondly, it should be noted that the UAV 1 adopts a large swept delta wing layout, has high maneuverability, has stealth performance, high dive attack speed, and a large attack angle. The fuselage platform 11 adopts a large swept delta wing and wing-body fusion overall layout, and the double vertical tail is located at the left and right wing tips respectively, which is used for equipment integration and loading to form a UAV 1 that can perform attack missions; the fuel system module 12 is mainly used for fuel loading and supply to ensure that the power unit 17 works normally.

[0034] A satellite-guided attack method for a drone, comprising: Step 1: Use the mission planning software to plan the UAV mission. Mission planning includes: determining the launch point, cruise route, mission target coordinates, and attack route. Specifically, the UAV mission profile mainly includes cruise X1-X2. n and attack G1— G n Two stages, before the flight, use the mission planning software to plan the mission and determine the launch point location X1 and the cruise route X1-X n , Attack Route G1 — G n , mission target coordinate G information.

[0035] Step 2: Perform automatic detection before launch and load the cruise route X1-X n and attack route G1 — G n .

[0036] Step 3: The drone is automatically launched from the launch point, automatically climbs after launch, and climbs to the specified altitude for cruising.

[0037] Step 4: When the horizontal distance from the mission target is 3 km, the UAV enters the attack route G1 - G n .

[0038] Step 5: Calculate the positional relationship between the drone's own position and the target position based on the drone's own position.

[0039] Step 6: Based on the positional relationship between the drone's own position and the target position, control the drone to fly at a constant altitude, with the heading aligned with the mission target.

[0040] Step 7: The UAV performs a 70° dive attack. When the UAV's altitude measured by the UAV's inertial navigation module is 100m~5km away from the ground where the mission target is located, the UAV is controlled to switch to pure inertial mode, where the pure inertial mode uses only inertial navigation for positioning and navigation.

[0041] Step 8: Until the UAV touches the ground in pure inertial mode, the ammunition module detonates to destroy the mission target.

[0042] It should be noted that the anti-interference capability of the UAV 1 is mainly as follows: first, the anti-interference satellite antenna module 13 is a combined navigation. If one of the satellite antennas fails and the corresponding satellite signal cannot be received, other satellites that are not interfered with can be used for navigation; second, if all the satellite antennas of the anti-interference satellite antenna module 13 fail, the UAV 1 uses the pure inertial mode of the inertial navigation module 14 for navigation; third, if Figure 5 and Figure 6 As shown in the figure, the mission route of this UAV system adopts a two-stage route. The UAV is on the cruising route X1-X n If the drone encounters interference, it will not attack; the drone will not attack on the attack route G1-G n If the drone encounters interference, it will switch to pure inertial mode to attack according to the situation.

[0043] like Figure 5 and Figure 6 As shown in Figure 2, after the drone is launched, 99% of the time it is on the cruise route X1-X n Flight, through the two-stage route setting, the onboard computer module 15 only needs to solve the UAV 1 in the attack route G1-G n The relationship between the position of the self and the position of the mission target at the time of the cruise is greatly reduced, the logic is simple, and the reliability is high. n Starting from the launch point X1, a certain distance X from the mission target point G n The cruise routes include: "I" shaped route and "N" shaped route. The "I" shaped route is as follows: Figure 5 As shown in the figure, according to the terrain conditions, a straight line or a broken line can be used, mainly for penetration and reaching the target point G directly; another type is an "N" shape, and the "N" shape route is as follows Figure 6 As shown, the "N"-shaped route is mainly used for penetration, while taking into account suppression and confusion. It can hover near the target and then attack along the attack route after circling for a certain period of time.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
