Galaxy Tracking Systems, L.L.C. VTU User’s Guide 1 INTRODUCTION This document is intended to provide a description of the operation and interfaces of the Vehicle Transceiver Unit (VTU). 2 SCOPE This document describes the operation and use of the Vehicle Transceiver Unit (VTU).
Galaxy Tracking Systems, L.L.C.
Galaxy Tracking Systems, L.L.C. VTU User’s Guide 5 SYSTEM OVERVIEW A typical configuration of Galaxy’s vehicle tracking system is illustrated below.
Galaxy Tracking Systems, L.L.C. VTU User’s Guide Broadcasting Unit (CBU), and a host of fixed receivers, Fixed Tracking Units (FTUs), placed strategically throughout the area of operations to ensure uninterrupted communications to member vehicles. The CBU operates under the direct control of the Central Command Center (CCC) which provides the primary operator interface to command and control the system.
Galaxy Tracking Systems, L.L.C.
Galaxy Tracking Systems, L.L.C. VTU User’s Guide range of 450 to 470 MHz at 2 watts. Frequencies are preset at the factory and selected for operation from the command center via the RF link. 6.1.3 System Controller The system controller is the heart of the VTU. It integrates the radio and GPS, contains the system logic the overall operation of the VTU.

Galaxy Tracking Systems, L.L.C. VTU User’s Guide on the Switch Box for each of the three inputs. When pressed, two of the switches issue silent alarms (SOS, Assistance) and the third toggles the unauthorized movement sensor between the armed and disarmed states. The remaining input is used to sense activation of the vehicle alarm system (if present). 7.2 Outputs Each of the three Switch Box switches have an associated status LED output (pins 5-7 on J1).
Galaxy Tracking Systems, L.L.C. VTU User’s Guide 8 VTU Operations 8.1 VTU Startup The VTU initializes first time power is applied after installation. Most importantly, the GPS receiver must find and track satellites, compute its position and synchronize to GPS time. A clear view of the sky and the GPS satellite constellation is required to do this. If the vehicle is parked in a garage or is shaded from the sky, it should be moved to a location with an unobstructed view of the sky.
Galaxy Tracking Systems, L.L.C. VTU User’s Guide While in this mode, the VTU will transmit an OUT OF SERVICE response to all commands except the IN SERVICE command. When OUT OF SERVICE, all in-vehicle alarms are disabled, (see SELF-ACTIVATION). 8.2.1.1 OUT OF SERVICE Operating Mode Commands The commands available with OUT OF SERVICE follow.
Galaxy Tracking Systems, L.L.C. VTU User’s Guide responds with one last IN SERVICE message to indicate the change in tracking status. Commanding the VTU OUT OF SERVICE also stops tracking reports, however, in this case, the VTU responds with a single OUT OF SERVICE message to report its change in operating mode. POLL REQUEST The POLL REQUEST equivalent to issuing a ONE SHOT to every member a group (fleet) of vehicles.
Galaxy Tracking Systems, L.L.C. VTU User’s Guide The SELF-ACTIVATION condition can only be cleared from the command center after the situation causing it has been addressed. Clearing the SELF-ACTIVATION extinguishes the LED. The reset command clears all Self Activations currently in process in the VTU, including those that have not been acknowledged. 14 Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this report.
