XY280R is a new generation of BDS / GPS / GLONASS / Galileo / QZSS full-system full-frequency high-precision RTK positioning receiver independently developed by Chengdu Beidou Nebula Technology Co., Ltd., based on a new generation of RF baseband and high-precision algorithm integrated GNSS SoC chip. It can track BDS B1I/B2I/B3I/B1C/B2a/B2b, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, QZSS L1/L2/L5, SBAS and other full-system and full-frequency points at the same time. It is suitable for high-precision navigation and positioning fields such as drones, lawn mowers, precision agriculture, surveying and mapping, and intelligent driving.
