AT3341 is a high-precision BDS/GPS dual-mode receiver board that supports GPS and BDS single-system timing and positioning and dual-system joint timing and positioning. The RF front-end chip and baseband chip are all independently developed by our company and have independent intellectual property rights. AT3341 contains 32 tracking channels, which can simultaneously receive all GPS and BDS visible satellites. AT3341 can be directly replaced by foreign timing boards, and the main interface signals are Pin-Pin compatible, and the installation hole is consistent.
