1)How the Trailer Tracks Service Works
Introduction
The Trailer Tracks service is the Omnitracs wireless system for identifying and locating trailers
for the trucking industry. This service provides cost-effective status monitoring and
management of trailers.
The TT150 system sends status information over-the-air (OTA) to the customer using cellular
functionality. The Trailer Tracks service is a comprehensive, end-to-end trailer identification and
location system, consisting of rugged mobile hardware, reliable network services, robust host
software, and extensive data integration capabilities.
Note: Trailer Tracks service refers to the wireless service that locates trailers. TT150 system
refers to the complete hardware system for the Omnitracs Trailer Tracks 150 service.
Trailer Tracks Service Network Description
The Trailer Tracks service consists of these network components:
Component
Description
Network Operations
Center (NOC)
This facility is responsible for processing and managing the data
traffic between the customer and the trailer. The NOC is located
in Las Vegas, NV.
Customer
The customer’s computer connects with the NOC in order to
receive information from the TT150 system.
Global Positioning
System (GPS)
GPS is a constellation of 24 strategically placed satellites. Signals
from the satellites determine the trailer’s location, which is then
reported to the NOC by the TT150 system.
Cellular Network
The TT150 system uses an existing cellular network to connect.
Trailer Tracks Web
Portal
This allows customers to receive information, request trailer
location information, and perform other functions. The user
interface can be accessed through the Omnitracs Services Portal
or for machine to machine interface, the data can be accessed
via web services integration.
The following illustration shows the interaction between the TT150 system network
components. The TT150 system sends information to the Omnitracs NOC through the cellular
network provider’s gateway. The gateway center sends the information via secure data lines to

8
the NOC. After the NOC receives the information, it sends the information to the Trailer Tracks
Web Portal. The GPS satellite constellation is used for location determination.
What is the Trailer Tracks Service?
The Trailer Tracks service is networking technology and hardware components installed on a
customer’s trailer. The hardware works to send information to customers over a cellular network
and also computes trailer location information using GPS technology.
The GPS and Cellular Network Systems
The TT150 system uses GPS to locate the trailer and a cellular network to deliver
information about the trailer to the customer.
The Global Positioning System
The Global Positioning System (GPS) is a worldwide radio-navigation system formed from a
constellation of satellites and ground stations. GPS uses the satellites as reference points to
calculate positions accurate within a few meters.
How the TT150 System Uses GPS
Signals received from at least four GPS satellites determine the TT150 system terminal’s
(i.e., trailer’s) location. The GPS receiver resides inside the TT150 system terminal to
determine the trailer’s position. The GPS receiver calculates the trailer’s location based on
the time that signals are received from the various satellites. The trailer’s location is sent
each time it communicates and is then available on the Trailer Tracks Web Portal.
The location data is retrieved automatically at regular intervals or can be requested at any
time.
The Terrestrial Wireless Network
The TT150 system uses digital technology to track customers’ trailers over a cellular
network. The TT150 terminal consist of a microprocessor, a wireless modem module, data
storage, antenna, and rechargeable battery.

2)TT150 System Component Overview
TT150 Components
TT150 Terminal
TT150 terminal with microprocessor, cellular modem, rechargeable internal battery pack,
cellular antenna, and GPS antenna. Attached to the terminal is a cable for recharging the
TT150 battery pack when the trailer is connected to a tractor.
The terminal is designed according to industry environmental specifications. The system
allows over-the-air (OTA) reprogramming of the terminal’s on-board firmware.
The TT150 terminal also has two LEDs for verifying cellular coverage and a GPS fix when
active.
The trailer operator (truck driver, loader, or unloader) does not need to access the terminal.
It should be mounted in a safe and secure place on the trailer.
Internal TT150 Battery
Internal to the TT150 terminal housing is a lithium ion rechargeable battery that is used
when the trailer is not connected to external power (i.e. not connected to a tractor). A
fully charged terminal will work for 90 days sending one message/position a day when
not powered. The battery will recharge when power is applied to the 7-way. The battery
is not serviceable.
Note
: The TT150 does not ship fully charged. It is recommended that the battery be
fully charged immediately after it is installed to provide the best messaging experience.
TT150 Power Cable Assembly
The TT150 power cable assembly is permanently attached to the TT150 terminal enclosure.
The power cable assembly contains fuse holders, which are separate from the power cable
assembly to ease routing of the cable assembly and make installation of the TT150 terminal
easier.
