L76-L

Миниатюрный GNSS модуль с встроенным МШУ

L76-L is a single receiver module integrating GLONASS and GPS sys-tems. With 33 tracking channels, 99 acquisition channels and 210 PRN channels, L76-L can acquire and track any mix of GPS, GLONASS and SBAS signals. Designed to be compatible with Quectel L76 module in the compact and unified form factor, L76-L provides a built-in LNA for better performance in weak signal areas.

Compared with using GPS only, enabling multiple GNSS systems gen-erally increases the number of visible satellites, reduces the time to first fix and increases positioning accuracy, especially when driving in rough urban environments.

ombining advanced AGPS called EASY™ (Embedded Assist Sys-tem) and proven AlwaysLocate™ technology, L76-L achieves the high-est performance and fully meets the industrial standard. EASY™ tech-nology allows L76-L to calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so L76-L can fix position quickly even at indoor signal levels with low pow-er consumption. With AlwaysLocate™ technology, L76-L can adaptive-ly adjust the on/off time to achieve balance between positioning accu-racy and power consumption according to the environmental and mo-tional conditions.

Its super performance makes L76-L ideal for automotive, industrial PDA, consumer and industry applications. Extremely low power con-sumption makes it easier to be applied to power sensitive devices, es-pecially portable applications.
