Dual-frequency, real-time kinematic (RTK) receiver for precise dynamic positioning Trimble’s MS750™ system is the most responsive GPS receiver on the market today.
The system sets a new standard for dynamic positioning by providing 20 mm (1″) accuracies, 20 times per second with a latency of less than 20 milliseconds. At higher latencies the MS750 provides positions of 10 mm (0.5″) 5 times per second.
Designed for easy integration, the MS750 adds precise positioning to dynamic guidance or control applications, such as those used in mining or construction, that require virtually instantaneous position reports multiple times per second.
The MS750 receiver operates reliably in mining and construction sites where high levels of radio interference are typical. Trimble’s Super-trak™ multibit GPS signal processing technology and Everest™ advanced multipath signal suppression keep measurements accurate even when satellite signals are weak.
The MS750 is programmed with a single command or configured via a simple built-in display or by using Microsoft Windows-based Configuration Toolbox software. The system can receive RTCM SC-104 differential GPS corrections simultaneously and includes support for the Controller Area Network (CAN) standard used by the automotive and construction industries to control and monitor electronic subsystems.
The MS750 is one of the Trimble MS Series receivers. These receivers share a common platform—this allows you to choose products suitable for your applications without having to redevelop software interfaces.

Hydrotide Automatic Tide Gauge
HYDROTIDE is a purpose designed recording tide gauge for long term monitoring of tidal activity in unattended remote locations.
Changes in pressure due to changes in head of water are detected by a semiconductor strain gauge transducer. These changes are recorded at pre-set intervals within the data loggers solid state memory.
The pressure transducer is manufactured from titanium and stainless steel and suitable for long term immersion in most liquids.
The transducer is connected to the logger via a single small diameter cable which also contains a micro bore pipe and thus allows atmospheric pressure to be applied to the rear of the transducers diaphragm. This provides accurate and calibration free compensation for changes in ambient atmospheric pressure.
The HYDROTIDE data logger is housed within a rugged, water tight aluminium enclosure. Connections are made via water tight connectors. Power is provided by a battery pack located within the HYDROTIDE case. This provides sufficient power to operate the unit for five years.
The user has a wide selection of sampling regimes which are preset into the logger using simple MSDOS PC based software. With a typical schedule of data averaged over 10 seconds and the average value recorded every ten minutes, the memory endurance of the system is 138 days.
The HYDROTIDE data logger is programmed to make a number of samples of the pressure transducer each lasting 0.75 seconds. By averaging these over an operator selecteable averaging period, wave motion is filtered out. The average depth value in metres is recorded and time/date stamped. Corrections for water density can be applied by calibrating in situ if required.
The MSDOS PC software allows loggers to be set up and data downloaded. Once downloaded, data may be archived to disk, printed as a time series, graphed, or exported to spread sheets and data bases.
The HYDROTIDE is supplied complete with 1 bar (10 metre) pressure transducer with 15 metres vented cable and operating manual.
