[0002] Deep space exploration, as a significant characteristic and indicator of a nation's scientific and technological development and comprehensive national strength, has attracted immense attention worldwide. Currently, 3D navigation of deep space probes is primarily achieved through very long baseline interferometry (VLBI) combined with ranging and Doppler velocimetry. However, this technology requires establishing communication links between the probe and ground-based observation stations, necessitating a global network of stations, limiting data transmission, and increasing communication errors as the distance between the spacecraft and Earth increases. Therefore, it is necessary to improve the autonomous navigation capabilities of spacecraft.
[0003] X-ray pulsar navigation (XPNAV) is a novel autonomous navigation method whose accuracy is unaffected by the relative position of the spacecraft and celestial bodies, making it one of the most promising deep-space navigation methods for the future. However, XPNAV accuracy is limited by the dynamic effects of the spacecraft's orbit, and current measurement capabilities are constrained by pulsar angular position errors, pulsar distance errors, and onboard atomic clock errors. These factors all reduce XPNAV's navigation accuracy. Therefore, how to measure X-rays from different angles and reduce measurement bias is a problem that needs to be solved. Summary of the Invention

[0016] To more clearly illustrate the present invention, it will be further described below with reference to the accompanying drawings. Of course, the scope of protection of the present invention is not limited thereto. Simple substitutions that can be made by those skilled in the art without creative effort are all within the scope of protection of this application.
[0017] Please see Figures 1 to 4This invention provides an X-ray angle deviation detection device, including a base 2, a support frame 1, a rotating device 3, and a measuring chip 5. The measuring chip 5 is disposed on the rotating device 3. The support frame 1 and the rotating device 3 are respectively disposed on the upper and lower sides of the base 2. The rotating device 3 includes a first rotating device 31 and a second rotating device 32 with identical structures. One side of the first rotating device 31 is connected to the base 2, and the other side is connected to the second rotating device 32 through a rotating table side plate 6. The first rotating device 31 and the second rotating device 32 are perpendicular to each other and are not in the same plane. One side of the second rotating device 32 is fixedly connected to the rotating table side plate 6, and the other side is provided with a chip fixing plate 4 for placing the chip 5. In this embodiment, the measurement chip is moved using two rotating devices in different directions, enabling the chip to move like a spherical cap. With the X-ray source stationary, this device allows for the movement of the concave spherical cap, ensuring that the distance from which the X-rays reach the silicon detector surface remains constant, while only the angle changes. Simultaneously, a support frame drives the rotating devices in linear motion, allowing for multi-angle and multi-directional movement of the measurement chip. Furthermore, all movements are performed at the millimeter level, ensuring accuracy. When X-rays irradiate the measurement chip, it generates a corresponding electrical output. When the irradiation angle is inconsistent, the output value generated by the measurement chip changes. Rotation at any position in space may cause deviations, thus the magnitude of the deviation can be determined based on the output value.
[0018] To achieve the above objectives, the first rotating device 31 includes a rotating plate 33, a receiving platform 34, and a rotating motor 35. The rotating plate 33 is disposed on the upper end of the receiving platform 34. A rotating gear 36 connected to the rotating plate is provided inside the receiving platform 34. The rotating motor 35 is disposed on the side of the receiving platform 34. A rack that meshes with the rotating gear 36 is sleeved on the motion shaft of the rotating motor 35, and the rack is inclined. In this embodiment, a connecting post connected to the rotating plate is provided at the lower end of the rotating gear. When the rotating motor rotates, it drives the rotating gear to rotate, thereby driving the rotating plate to rotate.
[0019] The base 2 includes a base plate 23 and drive motors. The drive motors include a horizontal drive motor 22 and a vertical drive motor 21, which are respectively disposed on adjacent sides of the base plate 23. A control main board is located inside the base plate 23. In this embodiment, two motors in two directions are provided at the edge of the base plate, which can be used to drive the base plate to move in multiple directions on a horizontal plane. In conjunction with the support frame and the rotating device, the measuring chip can be adjusted to different positions to meet usage requirements.
[0020] The support frame 1 is located at the lower part of the base 2 and includes a support motor 15, support rods, and support plates. The support plates include an upper support plate 12 and a lower support plate 11. There are two support rods connected in an "X" shape. The lower support plate 11 has a groove for the movement of the support motor 15. The support rods include a first support rod 14 and a second support rod 13. The two ends of the first support rod 14 are hinged to the upper support plate 12 and the lower support plate 11, respectively. One end of the second support rod 13 is hinged to the upper support plate 12, and the other end is connected to the motion shaft of the support motor 15. In this embodiment, the first and second support rods are arranged crosswise and connected in the middle to form a lever-like structure. When the support motor moves along the groove, it pushes the second support rod to move, thereby gradually changing the two support rods from the horizontal direction to the vertical direction, thus adjusting the height of the base and changing the vertical position of the base.
[0021] An angle sensor 7 is also provided. The angle sensor 7 is set inside the rotating device 3 and installed on the receiving platform 34 to monitor the rotation angle of the rotating plate 33. The chip fixing plate 4 includes a horizontal plate 41 and a vertical plate 42. The vertical plate 42 is set at the center of the horizontal plate 41 and is fixedly connected to the horizontal plate 41 as an integral structure. The horizontal plate 41 is fixed on the rotating plate 33, and the measuring chip 5 is fixed at the middle position of the vertical plate 42. In this embodiment, an angle sensor is provided to measure the rotation angle of the rotating device. Combined with the measurement data obtained from the measuring chip, this facilitates the acquisition of angle deviations. The chip mounting plate is designed with a special structure to capture X-rays emitted from multiple angle directions, avoiding the obstruction caused by the rotating device. Furthermore, placing the measuring chip in the center of the rotating device ensures that the distance from which X-rays reach the measuring chip remains constant during spherical motion, with only the angle changing, thus making the angle deviation measurement more accurate. In actual use, a linear motor can also be installed between the chip mounting plate and the second rotating device. The linear motor is fixedly connected to the rotating plate of the second rotating device. This allows the linear motor to drive the chip mounting plate in linear motion, compensating for the movement of the base plate, thereby expanding the range of motion of the measuring chip and increasing the measurement range. Moreover, since the linear motor is located at the center of rotation, three-axis translational adjustment is possible.
[0022] This invention also discloses an X-ray angle deviation detection system, including a monitoring module and a motion device. The motion device is any of the angle deviation detection devices described above. The monitoring module includes a transmission unit, a calculation unit, and a control unit. The control unit controls the motion device to perform corresponding movements, thereby measuring the direction of the X-rays and transmitting the measurement information to the calculation unit. After the calculation unit calculates the corresponding information, the data is transmitted through the transmission unit. In this embodiment, by utilizing the cooperation of the motion device and the measurement chip, the electrical output obtained on the measurement chip due to X-ray irradiation can be effectively obtained. The signal of this electrical output is transmitted to the monitoring module, and the magnitude of the deviation angle is calculated using the magnitude of the electrical output signal.
[0023] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
