About

About mosaic-X5 GNSS Module

mosaic-X5 is Septentrio's quad-band, low-power surface-mount GNSS receiver module for high-precision positioning in robots, autonomous systems and integrated navigation equipment. It tracks the principal GNSS constellations and current and future signals, including L-band, with embedded centimetre-level RTK and AIM+ interference mitigation.

The module supports update rates up to 100 hertz and RTK, PPP, SSR and SBAS corrections. Septentrio's development kit exposes Ethernet, serial, USB 2.0 and SD-card connections for evaluation; production integration uses the module and host-system interfaces selected by the equipment developer.
