L70 Hardware Design
L70_HD_V1.0 - 9 -
2. Product concept
The L70 GPS module brings the high performance of the MTK positioning engine to the industrial
applications. It is able to achieve the industry’s highest level of sensitivity, accuracy and TTFF with
the lowest power consumption in a small-footprint lead-free package. With 66 search channels and 22
simultaneous tracking channels, it acquires and tracks satellites in the shortest time even at indoor
signal level. The embedded flash memory provides capacity for storing user-specific configurations
and allows for future updates.
The L70 module combines with many advanced features including AlwaysLocate
TM
, EASY
TM
, and
AIC. These features are beneficial to reduce consumption and accelerate TTFF for L70 module.
The module supports various location, navigation and industrial applications including autonomous
GPS, SBAS (including WAAS, EGNOS, MSAS, and GAGAN), QZSS, and AGPS.
The L70 is an SMD type module with the compact 10.1mm x 9.7mm x 2.5mm form factor, which can
be embedded in customer applications through the 18-pin pads. It provides necessary hardware
interfaces between the module and customer’s board.
The module is fully RoHS compliant to EU regulation.
