Quectel L70-RL GPS Module

Quectel L70-RL, a low-cost ROM-based GPS module, brings the high performance of MTK positioning engine to industrial applications with its compact profile, ultra-low power consumption and fast positioning capability. Designed to be compatible with the Quectel L70-R module in the compact and unified form factor, Quectel L70-RL additionally provides a built-in LNA for better sensitivity in weak signal areas.

Combining advanced AGPS called EASY™ (Embedded Assist System) technology, Quectel L70-RL Module achieves the highest performance and fully meets the industrial standard. EASY™ technology ensures L70-RL GPS Module can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM memory, so Quectel L70-RL module can fix position quickly even at indoor signal levels with low power consumption.

With its extremely compact design, high precision and improved sensitivity, L70-RL is a perfect solution for a broad range of M2M applications such as portable device, automotive, personal tracking, security and industrial PDA.
