Full System Full Frequency Compact High Precision Board
ER-GB-01 Full System Full Frequency Compact High Precision Board is a compact high-precision board that supports RTK positioning. This type of board adopts a multi-system, multi-frequency and high-performance SoC chip-Nebulas-IITM with completely independent intellectual property rights. It also adopts a low-power design and provides millimeter and carrier phase observations and centimeter-level RTK positioning accuracy. The instantaneous RTK technology is especially suitable for high-precision navigation and positioning applications.
