L70, a SMD type module, brings the high performance of the 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) and proven AlwaysLocate? technology, L70 achieves the highest performance and fully meets the industrial standard. 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.


Additional feature of embedded logger function called LOCUS allows 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.


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

Packaging:

The module is sensitivity to moisture absorption. Before reflow, Module should be baked for 192 hours at temperature 40+5/-0 and <5% RH in low-temperature containers, or 24 hours at temperature 125±5 in high-temperature containers. Care should be taken that plastic tray is not heat resistant. Module should be taken out before preheating, otherwise, the tray maybe damaged by high-temperature heating.

Specifications
Self-AGPS EASY? Technology
EASY ? is the abbreviation for Embedded Assist System for quick positioning. With EASY ? technology, the GPS engine can calculate and predict automatically single ephemeris ( up to 3 days) when the power is on, and then save the predict information onto the memory. So the GPS engine can use the information for positioning later if there are not enough information received
from the satellites.
This function will be helpful for positioning and TTFF improvement under indoor or urban conditions.
TTFF Comparison
With EASY ? technology, L70 accelerates TTFF obviously.
Periodic Standby Mode
Periodic standby mode can control power on/off time of GPS periodically to reduce average power consumption,and on/off time can be configured by using PMTK command, for details, see the figure below. Periodic standby mode can be entered by sending the following PMTK command.
$PMTK255, Type, Run time, Sleep time, Second run time, Second sleep time
Run time: tracking period (ms)
Sleep time: standby period (ms)
Second run time: extended acquisition period (ms) when GPS acquisition fails during the Run time
Second sleep time: extended standby period (ms) when GPS acquisition fails during the Run time
Notes:
1. Normally, the GPS module will enter the periodic mode after successfully fixing position, but if acquisition fails, the GPS module still can enter this mode.
2. If GPS acquisition fails during the Run time, in order to ensure the success of reacquisition, it is better to set the longer Second run time.
Example: PMTK225, 2, 3000, 12000, 18000, 72000*16 for periodic mode with 3s in tracking mode and 12s sleep in standby mode. The average current is about 3.7mA.
AlwaysLocate Technology
AlwaysLocate is an intelligent controller of periodic mode.
L70 can adaptively adjust the on/off time to achieve balance between positioning accuracy and power consumption according to the environmental and motion conditions.So the average power consumption is lower in AlwaysLocate power saving mode than
that in periodic power saving mode, typical average power is 3mA.
Power consumption according to different conditions
L70 vs. Ucompany NEX-6Q
Specifications Comparison
Tracking Comparison
When driving across high buildings and making a turn, L70 module can still capturethe accurate tracking data.
When driving back and forth under the overpass, L70 module has small drift.
When driving into a tunnel, the GPS signal becomes weak. L70 can still fix positionfor a while.
