Section 1 Introduction
The L20 Solar-Cell Tracker is a lightweight, solar rechargeable, LTE-M Cellular enabled
GPS tracking device. With very long life due to rechargeability, the L20 is well-suited for
use in multiple longer studies.
Tracker configuration and data download is done via web browser. Login information
will be sent by ATS sales when tracker is shipped.
IMPORTANT: Your tracker IS NOT RUNNING until the attached magnet is
removed. More details in Section 4.
Data service HAS BEEN activated for all shipped L20 models.
Section 2 Theory of Operation
Quick Reference
• Data offload/programming is done solely over LTE-M (CAT-M1) networks over
several cellular carriers. Contact ATS to check coverage in your area.
• The trackers can recover from a drained battery. When low on battery in
hibernation/low light conditions, the tracker will stop collecting data and wait to
recharge. It will restart and transmit when charged.
• All collected data is retained in flash memory. If low on battery, or out of cell
service the unit will continue to collect data and save it. Data will be sent out
when the tracker finds cell networks during a scheduled transmission.
• Schedules can be changed post-deployment. Configuration is done via a web
interface. Login information is sent to users after ordering.
