OverviewFeaturePackagingDownload

 

L70-R, a low cost ROM-based GPS module, brings the high performance of MTK positioning engine to the industrial applications with compact profile, ultra low power consumption and fast positioning capability.

 

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

 

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