Description

Technical Field

[0001] This utility model relates to the field of positioning module technology, specifically a waterproof positioning module. Background Technology

[0002] Since drones cannot obtain sufficiently accurate coordinate data, flight control of drones in various countries adopts a combination of GPS satellite navigation systems and inertial navigation systems. Many drones contain sensing components such as accelerometers, gyroscopes, electronic compasses, and magnetometers. Furthermore, drones need to know their precise location when taking pictures, so they are equipped with GPS signal receivers, meaning they have built-in GPS modules. Navigation technology plays a crucial role in the research and commercial application of drones, ensuring flight safety throughout the entire process of takeoff, navigation, and landing. The GPS module provides precise positioning at all times during takeoff, hovering, and flight.

[0003] The UAV GPS module positioning and navigation system mainly consists of a GPS positioning system, an electronic map system, and a navigation system. Its working principle is as follows: Based on a pre-set synchronization time or according to the quality of the ground control station, the GPS module performs precise positioning of the UAV and displays the positioning results on the electronic map. The UAV's flight is corrected based on the deviation between its dynamic trajectory and the planned flight path. However, existing positioning modules of this type generally lack excellent waterproof performance and are not easily movable for protection. They also do not allow for flexible adjustment of the waterproof positioning module's position and signal connection to the outside, significantly affecting the safety of the waterproof positioning module and impacting the local signal strength during position adjustments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof positioning module, comprising a chassis and an arc-shaped groove. A base is installed at the top center of the chassis, and a central shaft is installed at the top center of the base. A horizontal arm is fitted onto the surface of the central shaft, and a vertical arm is installed at the top of the horizontal arm. A telescopic rod is slidably installed at the top of the vertical arm, and a drive shaft is movably installed at the top of the telescopic rod, with both ends of the drive shaft extending to the outside of the telescopic rod.
