CTT Node User Guide
The CTT Node™ is a mini-base-station that allows you to localize LifeTags™, PowerTags™ and HybridTags™ with a high degree of accuracy. If deployed in a grid fashion, and employing post-hoc analysis, the CTT Nodes can operate as pseudo-reverse-GPS, providing near GPS accuracy in optimal conditions. With the addition of calibration data, Nodes can provide presence/absence and distance estimate of instantaneous detections from supported tags.
The CTT Node uploads received tag detection data to the standard CTT SensorStation™, creating a dense, high resolution tracking network. Solar power recharges batteries in the CTT Nodes meaning no extra power cables or external solar systems are necessary.
Each CTT Node has a detectable range of about 250-300 meters, and is able to relay data to a CTT Base Station as far away as 1.5 kilometers.

up and running with your
CTT Nodes. For more detailed
information you can proceed to the sections below the
Quick Start Guide. Please provide any feedback via our
Customer Service Desk portal here.
What you will need:
SensorStationand a way to connect to it, either via ethernet or wirelessly
Unpack your Nodes.
Place Nodes outside in a sunny location and allow to fully charge for several days (more important if you will be testing with the magnet off)
Bring Nodes within range of an existing SensorStation (note: if not using antennas on your SensorStation, make sure Nodes are within a meter of the station).
Connect your computer to your SensorStation so you can view the web interface (for SensorStation operation consult the online install guide here).
Ensure your SensorStation has at least one radio tuned to detect Nodes (if this isn’t clear, consult the SensorStation online install guide).
With the magnets still on, a Node will transmit health
information once every five minutes and can do so for over two years
without recharging the battery. With the SensorStation web interface
open, you should begin to see Nodes checking in and showing up in the
Nodes list at the top of the SensorStation webpage like in the image
below. A properly functioning Node will send accurate GPS location and
GPS time. Note time is always in UTC. If GPS data is empty, or GPS time
is incorrect, either the Node is in a place where it cannot get a GPS
fix, or the GPS needs to be forced. See
Advanced Configuration via Node Client below for how to
force a GPS fix.
