Continuing to develop high-performance Global Positioning System (GPS) technology for machine control and marine applications, Trimble has introduced its MS750 Dual Frequency Real-Time Kinematic (RTK) receiver. The MS750 sets a new industry standard for dynamic positioning receivers with unprecedented accuracy and response time.
Like no other dual frequency GPS receiver on the market today, the MS750
provides the highest level of accuracy and response — 20 millimeter accuracy at 20 updates per second at 20 millisecond latency (20mm-2OHz-20ms). Dynamic platforms, including heavy machinery and marine survey/construction vessels, require instantaneous position reports multiple times per second to provide the operator with accurate and timely GPS information necessary for precise control.
Trimble’s MS750 provides reliable GPS information to precisely guide
tractors, mining and construction machinery, perform marine construction and hydrographic surveys as well as navigate marine vessels to improve efficiency, productivity and enhance safety.
With Trimble’s new 20mm-2OHz-20ms dynamic positioning standard, the MS750 delivers robust position information to control loop and navigation software. This responsiveness is matched with horizontal accuracies of two centimeters and vertical accuracies of three centimeters. The MS750 can also provide accuracy of one centimeter at a 5 Hz rate with a small increase in latency for the most precise applications.
Trimble’s MS750 was designed as a plug-and-play receiver for easy
integration and configuration. The compact, 2.25 pound receiver can plug into the user’s application with very little development using a RS232 or CAN/J1939 interface. The MS750 is the first RTK GPS receiver to include the Controller Area Network (CAN) protocol, a multiplexed network used in agriculture, construction and automotive industries for controlling and monitoring electronic subsystems. An easy-to-use application file interface allows the user to completely program the receiver’s operation with a single command. The MS750 can also be configured with the built-in display and keyboard interface, or with Windows(R)-based Configuration Toolbox software.
Reliable operation is paramount in challenging, dynamic positioning
environments, such as construction or mining sites, ports, harbors and along the coastlines, where radio interference may be experienced. The MS750’s accuracies, update rates and latencies make reliable operation possible through advanced technology patented by Trimble. Custom designed hardware with Super-trak GPS signal processing technology and Everest advanced multipath signal reduction provide superior GPS satellite tracking.
Simultaneously, the MS750 accepts both the RTCM format for differential
GPS corrections and Trimble’s published Compact Measurement Record (CMR) differential data. The receiver can choose the optimum source to provide seamless navigation.
The MS750 is expected to be available November 1998 from Trimble’s
worldwide dealer network.
