GNSS/GPS Positioning Module

Ebyte GNSS / GPS Positioning Module Selection Guide

Ebyte GNSS modules receive and process signals from global navigation satellite systems to deliver accurate position, velocity and time data. The product portfolio covers 6 major series with official part numbers, including SMD modules, all-in-one GMOUSE and industrial terminal form factors.

All series support multiple satellite constellations including BDS, GPS, GLONASS and Galileo, with positioning accuracy ranging from 1m to 2.5m CEP50. They are widely used in vehicle navigation, logistics tracking, precision agriculture, wearables, industrial monitoring and smart city scenarios.

5-Point Quick Selection Guide

Prioritize by accuracy grade. Choose ENM108-GN05 dual-band or E108-GN07S inertial navigation for high-precision scenarios (≤1m CEP50); choose E108-GN02/03/24 single-band or GMOUSE for standard positioning (1.5–2.5m); choose E108-GN03B / ENM108-GN008 single BDS for cost-sensitive basic positioning projects.
Match satellite systems to regional compliance. Select multi-constellation models for global market deployment; select E108-GN03B / ENM108-GN008 single BDS series for projects requiring BeiDou-only regulatory compliance.
Choose form factor by integration method. Select SMD modules for embedded PCB design; select GMOUSE for plug-and-play external installation; select industrial terminal series for field deployment with DIN rail mounting.
Select special features for harsh environments. Choose E108-GN07S inertial navigation for tunnels, urban canyons and other signal-interrupted scenarios; choose ENM108-GN05 dual-band for strong multipath interference environments.
Verify package size and interface. All SMD modules support standard TTL UART; industrial terminals provide RS485/RS232 for industrial bus integration; GMOUSE supports USB for easy connection to host devices.
