Trimble Trimmark 3 Base

Trimble Trimmark 3 Radio Modem
The TRIMMARK™ 3 radio
modem provides a convenient, versatile
means of establishing a
robust wireless data broadcast network
for real-time, high-precision
GPS survey and telemetry applications.
It’s a quality accessory for
the Trimble Toolbox of Integrated
Surveying™ Solutions.

The rugged, compact TRIMMARK
3 radio modem is designed for
use in tough environments and in a
variety of situations. The single unit is
usable as a base station, repeater station,
or rover receiver for maximum
versatility. However you use it, you’ll
appreciate its simplicity and famous
Trimble reliability and quality.

Select the power you need
The TRIMMARK 3 radio modem
provides selectable power outputs of 2,
10, or 25 Watts to support both shortand
long-range operations, conserve battery
life and minimize risk of interference
with other systems.

A 25W base unit broadcasts up to
15 km (8 miles) line-of-sight, under
optimal conditions. Path obstructions
and terrain can reduce the typical effective
range to 10 to 12 km (6 to 7 miles).
One or two additional units can be networked
as repeater stations to extend
range, minimize base station moves, and
provide seamless coverage around local
obstacles such as large buildings or hills.
The typical range of a 2W repeater is 5
to 8 km (3 to 5 miles).

A TRIMMARK 3 radio modem
broadcasts or repeats data to Trimble
survey-grade GPS receivers, such as the
Trimble 4700 or 4800, that either contain
an internal radio modem or are
being used with a TRIMMARK rover.
The TRIMMARK 3 is fully backward
compatible with the TRIMMARK IIe
radio modem, so it can be used in both
new and existing systems.

Conifgure it to your needs
The TRIMMARK 3 radio modem
can be configured completely and easily
in the office by using the supplied
WinFLASH utility on your computer.
Many functions also can be configured
in the field from the front panel or
from the Trimble Survey Controller™
software used with your GPS survey
receivers. The serial port communication
settings are easily set to match the
default settings on the GPS receiver.

You can configure each broadcast
network to operate on one of up to
20 programmed channels via a built-in
channel selector. Channel spacing of
either 12.5 or 25 kHz is programmable
at the factory or by a service provider.

To reduce the risk of interference
in a congested RF environment, you
can use the built-in audio speaker to
monitor activity on the selected channel.
The unit also can automatically
monitor the channel using its softwareselectable
carrier detect function to
detect other users on the channel
before transmitting.
The TRIMMARK 3 radio modem
is available as a stand-alone product as
well as in convenient base and repeater
equipment sets. Available in three frequency
bands, the TRIMMARK 3
radio modem is designed to meet the
licensing requirements of many countries
around the world.
