L26-M33中文资料GNSS L26数据手册Quectel规格书

描述 Description

The L26 is a multi-constellation GNSS receiver module capable of tracking GPS, GLONASS (or BDS), Galileo and QZSS in the L1 band concurrently. With 33 tracking channels, 99 Acquisition channels and 210 PRN channels, the L26 can acquire a flexible mix of multiple constellation signals.

In contrast to single constellation GPS only receivers, the L26 multi constellation GNSS receiver has access to a vast increase in visible satellites and thus has a reduced TTFF and improved positioning accuracy even in dense urban canyons.

The combination of EASY (Embedded Assist System) technology, EPO (Extended Prediction Orbit) technology, and GLP (GNSS Low Power) mode, lends L26 module high performance, low power consumption and full compliance with industrial standards. The EASY technology allows the module to automatically calculate and predict orbits by using the ephemeris data (up to 3 days) stored in internal RAM. The EPO technology enables the module to download predicted orbits data (up to 30 days ) through the EPO server, resulting in a quick position fix with low power consumption, even at lower signal levels. GLP technology allows L26 to adaptively adjust the on/off time based on environmental conditions and motion information to strike a balance between positioning accuracy and power consumption.

Its enhanced performance makes the L26 ideal for industrial PDA, consumer and industry applications. Extremely low-power consumption makes it a great solution for power-sensitive applications, such as portables.
