[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 2024100106122, filed with the Chinese Patent Office on January 3, 2024, entitled “GNSS receiver and surveying and mapping equipment,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the field of GNSS technology, and in particular to a GNSS receiver and surveying and mapping equipment. Background Art

[0004] GNSS receivers are surveying and measurement devices based on the Global Navigation Satellite System. Currently, GNSS receivers are widely used in various fields. For example, they are indispensable tools in navigation, aerospace, and geographic surveying. They are also widely used in agriculture, transportation, environmental monitoring, earthquake early warning, and other fields.

[0005] The development of GNSS receivers must consider many factors simultaneously, such as measurement accuracy, weight, and durability. In addition, the reliability of the measurement data during use of the GNSS receiver is also one of the key considerations.

[0006] GNSS receivers typically combine satellite navigation and photogrammetry to acquire highly accurate three-dimensional coordinates. They receive signals from multiple satellites, process and analyze them, and then use the measured data to calculate positions. These are used for precision geodetic and engineering surveying. Therefore, GNSS receivers require high accuracy from camera measurements. Existing GNSS receivers typically acquire measurement data by raising a centering pole upward and pointing the camera downward or backward.

[0007] However, in some scenarios, there are usually shades of trees or other buildings, such as rooftop sheds, light billboards and other obstructions below the GNSS receiver, which block the camera's shooting route, thereby affecting the accuracy of the GNSS receiver's video measurement, and further affecting the accuracy and reliability of the GNSS receiver's positioning solution results.

[0008] Therefore, in the development of GNSS receivers, how to improve the reliability of measurement data of GNSS receivers is a technical problem that needs to be solved urgently in GNSS receiver technology.

[0009] Public content

[0010] The present disclosure aims to provide a GNSS receiver and surveying equipment, which have high measurement data reliability.

[0011] The present disclosure is achieved through the following technical solutions:

[0023] In the technical solution of the disclosed embodiment, the protrusion protrudes from one side of the bracket body and penetrates the antenna, while the second through-hole extends through the bracket body and the protrusion. This means that when the first camera is positioned in the first through-hole, the protrusion fits over the first camera, reducing the risk of damage to the first camera and improving the reliability of the GNSS receiver.

[0024] In some embodiments, the first camera is loosely fitted into the second through hole.

[0063] In some embodiments, the first camera 112 and the first camera window 111 are correspondingly arranged, that is, the first camera 112 can capture images through the first camera window 111 .

[0064] In some embodiments, the axis of the first camera 112 may coincide with the axis of the first imaging window 111 .

[0065] In some embodiments, when using the GNSS receiver 1 for surveying and mapping, the first camera 112 can be facing upward, that is, the camera lens is facing upward.

[0069] In some embodiments, when the GNSS receiver 1 is used for surveying and mapping, the upper housing 11 is located above the lower housing 12 .

[0070] According to the technical solution of the embodiment of the present disclosure, the first camera window 111 is arranged in the central area of ​​the upper shell 11, so that the first camera 112 can obtain measurement data in the vertical direction during shooting, reducing the risk of the first camera 112 being blocked by the upper shell 11 during shooting, thereby allowing the first camera 112 to have a wider shooting angle and increasing the shooting range.

[0071] 1 to 4 , in some embodiments, the GNSS receiver 1 further includes a lens 113 , which is disposed on the first imaging window 111 .

[0087] In some embodiments, the antenna bracket 40 may be made of copper.

[0088] In some embodiments, during the use of the GNSS receiver 1, the first camera 112 needs to be electrically connected to the mainboard 20 and the first camera 112 needs to shoot upward, and the antenna bracket 40 needs to be arranged above the mainboard 20 and below the antenna 30.

The second through hole 41 extends through the bracket body 42 and the protrusion 43. In other words, when the first camera 112 is positioned in the first through hole 31, the protrusion 43 is positioned within the first camera 112, reducing the risk of damage to the first camera 112 and improving the reliability of the GNSS receiver 1.

[0096] 3 to 5 , in some embodiments, the first camera 112 is loosely fitted into the second through hole 41 .

[0097] In some embodiments, the antenna bracket 40 is provided with a second through hole 41 that extends through the bracket body 42 and the protrusion 43.
