Trimble MS750
Trimble MS750 Dual Frequency RTK
Receiver
The MS750 represents the
highest level of accuracy and
response available from a dual
frequency GPS receiver. The
receiver is specifically designed to
allow the easy integration of
reliable centimeter-level positions
to any guidance or control
application.
Accuracy and Response Times
Dynamic platforms, require
virtually instantaneous position
reports multiple times per second.
The MS750 delivers positions to
guidance or control loop software
twenty times per second with a
latency of less than 20
milliseconds. This responsiveness
is matched with a horizontal
accuracy of two centimeters and
vertical accuracy of three
centimeters. For the most precise
applications, the MS750 provides
one centimeter accuracy
horizontally at a 5 Hz rate with a
small increase in latency.
Interfacing and Configuration Ease
The MS750 is designed to plug
right into your application with
minimal development. An easy touse
application file interface
enables the user to completely
program receiver operation with a
single command. Alternately, the
receiver can be configured via the
user-friendly built-in display and
keyboard interface, or by the
included Windows-based
Configuration Toolbox software.
Multiple configurations can be
stored in the receiver as files and activated when desired. Local
datum and transformation
parameters may be loaded directly
into the receiver. Therefore,
output grid coordinates are
compatible with GPS and
traditional survey systems that
may be in use on the same site.
ASCII or Binary messages may be
output through any of the three
bi-directional serial ports. The
receiver also includes support for
the industry standard CAN
(Controller Area Network)
interface.

Advanced Technology
The accuracies, update rates and
latencies available in the MS750
are made possible through a GPS
architecture specifically designed
for demanding dynamic
positioning applications. Reliable
operation in the most adverse
environments, such as radio
interference experienced at construction or mining sites, is a
strict requirement. Custom
designed hardware with
Supertrakô multibit GPS signal
technology and Everestô advanced
multipath suppression provide
superior tracking especially for
weaker, low elevation satellites.
Both the RTCM format for
differential GPS corrections and
Trimble’s published Compact
Measurement Record (CMR)
differential data can be received
simultaneously, allowing the
receiver to choose the optimum
source and provide seamless
navigation. Available as an option
is the ability to calculate the
baseline vector between two
moving receivers to centimeter
accuracy. The MS750 addresses a
vast range of applications in the
field of machine positioning,
guidance and control.
