Component Description
Network Management
Facility (NMF)
This facility is responsible for processing and managing the
message traffic between the dispatch center and the fleet.
Within the NMF is the Network Management Computer
(NMC), which actually receives and handles the message
traffic. The NMF is located at QUALCOMM, Inc., in San
Diego, CA.
QUALCOMM Dispatch
Software (QTRACS
®
)
This is the software on the trucking company’s dispatcher
computer. This is the dispatcher’s interface with the
OmniVision system. It allows the dispatcher to send and
receive messages, request MCP location information, and
perform other dispatcher functions. QTRACS/400 and
QTRACS/Windows customers communicate with the NMC
via dialup using PPTP or a frame relay connection.
QTRACS/Web customers communicate via the NMC using
RI/Web client over a PPTP connection.
Data Satellite
(uses Ku-band signals)
This satellite handles all two-way message traffic between
the vehicle and the NMC. Located approximately 22,300
miles over the equator at 103° west longitude (south of
Texas ) .
GPS Positioning Satellites GPS uses 24 satellites to provide vehicle positioning
information.
Mobile Computing Platform
(MCP)
The MCP is the driver’s interface with the OmniVision
system. It allows the driver to send and receive messages.
The MCP is mounted in the vehicle.
