The Ebyte E108-GN07 Series is a high-precision, multi-band GNSS positioning module manufactured by Ebyte. It supports BDS (Beidou), GPS, GLONASS, Galileo, QZSS and SBAS, receives L1, L2 and L5 frequency signals, and outputs data over a UART interface. The series comes in three versions: E108-GN07IS (dual-frequency with inertial navigation), E108-GN07RS (dual-frequency RTK positioning) and E108-GN07RIS (dual-frequency RTK combined with inertial navigation).

Typical Applications
Suitable for applications that need centimeter-level or continuous positioning, such as drones and UAVs, agricultural machinery automatic steering, surveying and mapping, robot lawn mowers, autonomous robots, vehicle navigation and tracking, and precision timing, including environments with weak or blocked satellite signals where inertial navigation keeps positioning continuous.
