Tyni GPS Module With Ultra Low Consumption

The GPS module L70 adopts MT3339 chipset. With the MTK positioning engine, L70 achieves the highest performance and fully meets the industrial standard. L70 has 66 acquisition channels, 22 simultaneous tracking channels, and advanced AGPS technology called EASY™(Embedded Assist System).

EASY™ technology ensures L70 can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so L70 can fix position quickly even at indoor signal levels with low-power consumption.

With AlwaysLocate™ technology, L70 can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions. Featuring tiny design, low power consumption and high precision and sensitivity, L70 are suitable for portable device and automotive, personal tracking, industrial PDA and many other applications.
