KM100 Single-frequency High-precision RTK Positioning Module
KM100is a high-precision RTK module developed by Kepler.
KM100 is a high-precision RTK module developed by Kepler. It supports all global civilian navigation satellite systems (GPS, BeiDou, GLONASS, Galileo, and QZSS), integrates a single-frequency RTK engine, and enables centimeter-level positioning, making it suitable for navigation and positioning applications in industrial and consumer fields.
Features:
· Supports GPS, BDS, GLONASS, Galileo, and QZSS.
· Built-in RTK engine for centimeter-level positioning accuracy.
· Integrated single-frequency RTK technology.
· Built-in active antenna short-circuit protection.
· Configurable peripheral IO pins.
· Single-power wide-voltage design for low-power and high-precision solutions.
