Leica Geosystems will supply 36 GRX1200 GPS reference stations, along with Spider GPS network control software, which will be incorporated into an integrated network of base stations deployed at strategic locations across the state, providing high-accuracy RTK data for a wide range of surveying and construction applications.
Earlier this year, Leica Geosystems also supplied 84 System 1200 dual-frequency GPS surveying instruments and GeoOffice post-processing software to the New York DOT.
"The wide-area CORS network will eliminate the need to establish local control or set up temporary field reference stations at specific job sites," said Gerard Manley, vice president of engineered solutions for Leica Geosystems. "The CORS data will be made available to state agencies, third-party contractors, construction firms and surveyors for collecting and validating position information in the field throughout the service area."
The GRX1200 incorporates Leica Geosystems' exclusive SmartTrack GPS measurement engine, which provides unsurpassed performance under all conditions. The SmartTrack receiver acquires all visible satellites within seconds, provides clean high-accuracy code and phase measurements with excellent signal-to-noise ratios, provides reliable tracking to low elevations, suppresses multi-path and resists jamming. The units are designed to operate around the clock unattended in remote, hostile environments. They are built with a rugged magnesium housing and meet MIL-STD-810F specifications.
The Spider GPS software is designed to fulfill all requirements for the management, operation and continuous monitoring of a network of GPS reference stations. It handles all aspects of configuration and control for local and unattended remote GPS sensors, periodic data downloads from sensors, data archiving and distribution, system monitoring and data logging. Incorporated in the new Spider GPS software release is the SpiderNet module, which provides enhanced real-time network and analysis and error modeling over all reference stations, utilizing the new RTCM V3.0 network correction message standard based on the Master-Auxiliary Concept (MAC).
"The New York State DOT has an impressive vision of a uniform high-quality integrated construction management system that will provide a level of efficiency, productivity and accuracy for construction, engineering and surveying projects throughout the state," said Manley. "We at Leica Geosystems look forward to continuing to work with them to implement this exciting master plan."
