Quectel L70 GPS Module

Quectel L70, an SMD type module, brings the high performance of MTK positioning engine to the industrial applications with a compact profile, ultra-low power consumption and fast positioning capability. Combining advanced AGPS called EASY™ (Embedded Assist System) and proven AlwaysLocate™ technology, L70 achieves the highest performance and fully meets the industrial standard.

Combining advanced AGPS called EASY™ (Embedded Assist System) and proven AlwaysLocate™ technology, L70 achieves the highest performance and fully meets the industrial standard. EASY™ technology ensures Quectel GPS L70 can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM memory, so L70 GPS Module can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate™ technology, L70 module can adaptively adjust the on/off time to achieve the balance between positioning accuracy and power consumption according to the environmental and motion conditions.

The additional feature of embedded logger function called LOCUS allows Quectel L70 to log position information to internal flash memory at default intervals of 15 seconds and provide typically more than 16 hours log capacity without adding cost.

The Fitness Low Power (FLP) feature provides low power GPS solution for fitness application. It is an optimized solution for wearable, fitness and tracking device and only costs 5mA current consumption in static receiving.

With its tiny design, high precision and sensitivity, Quectel L70 GPS Module is perfectly suitable for a broad range of M2M applications such as portable device, automotive, personal tracking, security and industrial PDA.
