Description

Technical Field

[0001] This utility model belongs to the field of aerospace technology, specifically a satellite constellation orbit correction device based on inter-satellite links. Background Technology

[0002] Satellite constellation orbit correction systems are crucial for ensuring satellites operate within their designated orbits. They correct orbital deviations caused by various factors by adjusting the satellites' speed and orientation. Inter-satellite links are communication links connecting communication facilities on Earth with satellites in space. Ground stations monitor satellite orbital parameters and generate orbital correction commands.

[0003] Existing satellite constellation orbit correction devices are mostly built in uninhabited, open areas, requiring effective protection against severe weather to ensure timely signal transmission and reception for the satellite constellation during use and to prevent ground positioning from being lost. Traditional ground stations struggle to implement comprehensive protective measures, resulting in a significantly shortened equipment lifespan and increased maintenance burden. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, this utility model provides a satellite constellation orbit correction device based on inter-satellite links. It solves the problem that existing satellite constellation orbit correction devices are mostly built in uninhabited open areas, requiring effective protection against severe weather, and can transmit and receive signals for the satellite constellation in a timely manner during use to avoid ground positioning loss. Traditional ground stations are unable to implement comprehensive protection measures, resulting in a significant reduction in the service life of the equipment and an increased maintenance burden.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a satellite constellation orbit correction device based on inter-satellite links, comprising a ground station body, a receiver mounted on the top of the ground station body, four supports fixedly mounted on the bottom of the receiver, an insulating layer provided on the outer side of the supports, a discharge tube fixedly mounted on the bottom of the support away from the ground station body, a shielding mesh fixedly connected to one side of each of the four supports, a retraction assembly mounted on the top of the support away from the ground station body, the retraction assembly including a lifting plate, a storage slot provided on the top of the support corresponding to the position of the lifting plate, an electric push rod fixedly mounted on the bottom of the storage slot, the top of the electric push rod fixedly connected to the lifting plate, an antenna vibrator fixedly mounted on the top of the receiver, a protrusion fixedly mounted on one side of the bottom of the ground station body, a heat dissipation assembly fixedly mounted on the top of the protrusion, the heat dissipation assembly including a mounting shell.

[0006] As a further embodiment of this utility model: an antenna cover is fixedly installed on the outer side of the top of the receiver, and a filter is installed on the top of the receiver.

[0007] As a further embodiment of this utility model: sliders are fixedly installed on the bottom of both sides of the lifting plate, and a groove is provided in the storage groove at the position corresponding to the slider.

[0008] As a further embodiment of this utility model: a fan mechanism is installed inside the mounting housing, and a filter screen is provided at the top of the mounting housing corresponding to the position of the fan mechanism.

[0009] As a further embodiment of this utility model: the bottom of the mounting shell is provided with drainage holes, and the number of drainage holes is several.

[0010] As a further embodiment of this utility model: a heat-conducting mesh is sleeved on the outside of the receiver, and a pad is fixedly installed on the bottom of the ground station body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This inter-satellite link-based satellite constellation orbit correction device, by setting up a shielding net, discharge tube, antenna vibrator, and receiver, and installing the ground station body within the working range, then controls the operation of the electric push rod to drive the movement of the lifting plate. Through the support and limiting effect of the slide groove on the slider, the slider can assist the lifting plate to move up and down in the storage slot. At this time, the shielding net can be pulled up to achieve isolation and protection from the outside world. The discharge tube can reduce the damage of lightning to the equipment during thunderstorms. The antenna cover can effectively prevent rainwater from corroding the antenna vibrator. The filter can enhance signal transmission, enabling the antenna vibrator to stably send detection signals to the satellite constellation. Finally, through the receiver and the computing equipment of the external headquarters, the satellite constellation orbit can be corrected.

[0013] 2. This satellite constellation orbit correction device based on inter-satellite links, by setting up pads, heat-conducting nets, filters, and drainage holes, raises the overall installation height of the device during the stable operation of the ground station, preventing rainwater accumulation from affecting the device's signal reception. In hot weather, the heat-conducting net effectively absorbs excess heat from the receiver, and then controls the fan mechanism to cool the surface of the heat-conducting net. The filter prevents impurities such as leaves from entering and clogging the fan mechanism, ensuring its long-term operation. In addition, the drainage holes keep the inside of the mounting shell dry, preventing prolonged immersion from reducing the service life of the fan mechanism, thus achieving comprehensive protection.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a satellite constellation orbit correction device based on inter-satellite links, including a ground station body 1, a receiver 2 installed on the top of the ground station body 1, an antenna cover 3 fixedly installed on the outer side of the top of the receiver 2, and a filter 10 installed on the top of the receiver 2. By providing the antenna cover 3 and the filter 10, the antenna cover 3 can effectively prevent rainwater from eroding the antenna vibrator 9, while the filter 10 can enhance signal transmission and reduce external interference.

[0021] A heat-conducting mesh 13 is fitted on the outside of the receiver 2, and a pad 14 is fixedly installed on the bottom of the ground station body 1. With the heat-conducting mesh 13 and the pad 14, the heat-conducting mesh 13 can absorb the heat of the receiver 2 in hot weather, while the pad 14 can raise the overall height of the device and improve the protection against rainwater accumulation in the surrounding area.

[0022] Four brackets 4 are fixedly installed at the bottom of the receiver 2. An insulating layer 5 is provided on the outside of the brackets 4. A discharge tube 6 is fixedly installed at the bottom of the end of the bracket 4 away from the ground station body 1. A shielding mesh 7 is fixedly connected to one side of each of the four brackets 4. A take-up and release assembly 8 is installed on the top of the side of the bracket 4 away from the ground station body 1. The take-up and release assembly 8 includes a lifting plate 801. A slider 803 is fixedly installed at the bottom of both sides of the lifting plate 801. A groove 804 is provided in the storage slot 802 at the position corresponding to the slider 803. By providing the groove 804, the groove 804 can support and limit the movement of the slider 803, so that the lifting plate 801 can be driven vertically by the electric push rod 805.

[0023] A storage slot 802 is provided on the top of the bracket 4 at the position corresponding to the lifting plate 801. An electric push rod 805 is fixedly installed at the bottom of the storage slot 802. The top of the electric push rod 805 is fixedly connected to the lifting plate 801. An antenna vibrator 9 is fixedly installed on the top of the receiver 2. A protrusion 11 is fixedly installed on one side of the bottom of the ground station body 1. A heat dissipation component 12 is fixedly installed on the top of the protrusion 11. The heat dissipation component 12 includes a mounting shell 1201. A fan mechanism 1202 is installed inside the mounting shell 1201. A filter screen 1203 is provided on the top of the mounting shell 1201 at the position corresponding to the fan mechanism 1202. By providing the fan mechanism 1202 and the filter screen 1203, the fan mechanism 1202 can be controlled to cool the surface of the heat conduction net 13, and the filter screen 1203 can prevent impurities such as leaves from entering and clogging the net.

[0024] The bottom of the mounting housing 1201 is provided with a drainage hole 1204. There are several drainage holes 1204. By providing drainage holes 1204, the inside of the mounting housing 1201 is kept dry through the unblocking effect of drainage holes 1204, avoiding long-term soaking and reducing the service life of the fan mechanism 1202.

[0025] The working principle of this utility model is as follows:

[0026] After the ground station body 1 is installed, the electric push rod 805 is controlled to move the lifting plate 801. The sliding groove 804 limits the movement of the sliding block 803, which assists the lifting plate 801 in moving up and down within the storage slot 802. During operation, the antenna cover 3 effectively prevents rainwater from corroding the antenna vibrator 9. The insulation layer 5 isolates the discharge tube 6, reducing lightning damage during thunderstorms. Simultaneously, in response to severe weather changes, the shielding mesh 7 can be lifted by the lifting plate 801 to provide isolation and protection from the outside world. The pad 14 raises the overall installation height of the device, preventing rainwater accumulation from affecting the signal reception. In hot weather, the heat-conducting mesh 13 can effectively absorb excess heat from the receiver 2, and then control the fan mechanism 1202 to cool the surface of the heat-conducting mesh 13. The filter 1203 can prevent impurities such as leaves from entering and clogging, ensuring the long-term operation of the fan mechanism 1202. In addition, the drainage hole 1204 can keep the inside of the mounting shell 1201 dry, avoiding prolonged soaking and reducing the service life of the fan mechanism 1202. The filter 10 can enhance signal transmission, enabling the antenna vibrator 9 to stably send detection signals to the satellite constellation. The satellite constellation orbit can then be corrected by an external computing device.
