CrossCheck XR.
The CrossCheck GSM/GPRS unit includes the following standard
features:
• A sophisticated event handler for OTA configuration
• One serial port for messaging communication with the optional
EchoLDX Message Terminal (PN 46722-00)
• discrete inputs, pulse counters, and outputs for vehicle
peripheral support
CrossCheck GSM/GPRS 850/1900 Installation Manual 7
1 Overview
• Configurable Zone Logic Configuration packet:
– Geo-fence area for Job Sites
– Geo-fence area for Home Sites
– Entry and exit speed limits for Site Dispatch purposes
– Site dispatch time out
– Minimum duration to detect entry/exit regions
• Storage of events and positions for up to one week while the
CrossCheck GSM/GPRS is out of the coverage area
Note – The CrossCheck GSM/GPRS 850/1900 does not support the
TAIP protocol, or the IQEventEngine firmware that is used by some
CrossCheck products.
1.2.2 Optional system components
The EchoLDX™ Message Terminal is available as an optional system
component. The Message T erminal is the messaging user interface in a
fleet asset management system. It displays Text Messages, Job Sites,
and Home Sites that the Telvisant Wireless Gateway sends to the
CrossCheck GSM/GPRS unit.
1.2.3 Antenna requirements
To operate correctly, the CrossCheck GSM/GPRS unit must be
connected to a GPRS antenna and to a GPS antenna. Because the type
of antenna required depends on the application and installation
location, the standard CrossCheck GSM/GPRS system does not
include antennas. Trimble manufactures both bulkhead and magnetic
mount GPRS and GPS antennas for use with a
CrossCheck GSM/GPRS unit. These antennas must be ordered
separately.
For information on the antennas that are available from Trimble, and
their installation, see Chapter 2, Installation. For ordering information,
see Appendix A, Specifications.

1.3 CrossCheck GSM/GPRS Applications
The Trimble Mobile Solutions (TMS) division provides a set of core
products, around which you can build systems and applications for
managing your transport and logistics assets.
TMS products and services provide the building blocks at both ends o f
the asset management system, including the on-board units mounted
in the vehicle and the Telvisant Web-based gateway for dispatch and
control applications.
The central on-board component is the CrossCheck GSM/GPRS unit.
You can use the unit as a standalone unit, or interface it with external
accessories and sensors to make it function as part of an on-board
system.
The optional EchoLDX Message Terminal provides a driver interface
for exchanging messages and generating event reports.
The CrossCheck GSM/GPRS and applications can do the following:
• Automate vehicle status changes for dispatching applications.
• Determine time spent and distance traveled on jobs for
accounts-payable systems.
• Improve efficiency by detecting unauthorized vehicle stops or
off-route acti vities.
• Improve customer service by advising customer service systems
of delays.
• Drive compliance by keeping a time-stamped log of activities.
• Improve safety by indicating speed limit violations.
• Identify unauthorized use of equipment and detect theft.

1.4 The Global Positioning System
The Global Positioning System (GPS) is a satellite-based navigation
system operated and maintained by the U.S. Department of Defense.
GPS consists of a constellation of 24 satellites providing world-wide,
24-hour, three-dimensional (3D) coverage. Although originally
conceived for military needs, GPS has a broad array of civilian
applications including timing, surveying, fleet management, marine,
land, aviation, and vehicle navigation. As a satellite-based system,
GPS is free from the limitations of land-based systems, which have
limited coverage and whose accuracy varies with geographic location.
A GPS receiver calculates an accurate position by computing its
distance from GPS satellites orbiting the earth. This process is called
satellite ranging. A GPS receiver can also provide precise time, speed,
and course measurements, which are important for vehicle mobile
positioning and communications applications.
1.5 GPS Receiver
The CrossCheck GSM/GPRS unit includes an advanced GPS receiver ,
which provides the position, course, speed, and time information
required for AVL and fleet management applications.
Overview 1
The integrated GPS receiver in the CrossCheck GSM/GPRS unit
features an eight-channel digital signal processor which operates at the
GPS L1 frequency (1575.42 MHz) and processes the
Coarse/Acquisition (C/A) code portion of the GPS signal. The RF and
digital signal-processing components of the GPS module are custom
integrated circuits designed by Trimble.
