Fibocom G041I is a dual-band, multi-constellation GNSS module with deadreckoning which supports GPS、BDS、QZSS satellite signals.
Combining GNSS positioning and inertial navigation technology, G041I can acquirehigh-sensitivity positioning, as well as rapid signal tracking and acquisitioneven under the poor signal areas (such as tunnels, underground parking, etc.), andprovide continuous and accurate positioning for navigation applications.
Besides, AGNSS can enhance the sensibility of acquisition in shorter timeeven under weak signal environment. The offline ephemeris feature can extendthe operating time to up to 6 days. G041I also provide advanced power management, enabling low-power GNSS sensing and position fix, which makes it suitable for theindustrial and consumer applications.
With highsensitivity, high precision and other performance advantages, G041I is an idealsolution for automotive navigation, lane-level navigation, fleet management services..
