AI Technical Summary
During the miniaturization process of RTK receivers, indicators such as phase center stability and accuracy decrease, resulting in low positioning accuracy.
A metal layer is placed on the housing of the RTK receiver. The shape and position of the metal layer are designed as a centrally symmetrical figure, and the maximum size is 1/8 to 1/4 of the wavelength of the RTK antenna frequency. The phase center accuracy and signal-to-noise ratio are improved by conforming with the housing.
Without increasing size, it significantly improves the positioning accuracy and stability of RTK receivers, while reducing costs and providing a high-performance, miniaturized product.
