Thales Navigation has announced that the city of Shanghai, China, has selected its Ashtech® Micro-Z(TM) Continuous Geodetic Reference Station and Geodetic Base Station Software for its multifunction reference network. The Ashtech Micro-Z is expected to assist Shanghai in predicting monsoon rains for the protection of lives and property, surveying sites for new development and repair, guiding city workers and law enforcement to problem areas, and keeping Shanghai’s Huangpu River and Hangzhou Bay open for shipping by aiding dredging operations.
The Shanghai municipal government selected the Ashtech Micro-Z station for its ability to meet the government’s stringent requirements for proven data quality, flexibility in serving a variety of applications, and fully automated data collection. Thales Navigation’s superior and dedicated product support was also a contributing factor to the purchase decision. The first 14 stations are currently being installed in the Shanghai/Pudong region, and five additional stations will be installed within the first half of this year.
The Ashtech Micro-Z is a powerful permanent GPS reference station, designed for continuous use and effective collection of high-quality data. The Ashtech Micro-Z makes totally automated data collection possible through a combination of MicroManager Software and Geodetic Base Station Software, as well as robust modem integration. The Ashtech Micro-Z is unique in its integration of the ZMODEM protocol, which is more effective for data transfer than the traditional XMODEM.
The Ashtech Micro-Z reference station network, using the Ashtech Geodetic Base Station Software, will serve many users by automatically sending data to the Shanghai Institute of Survey and Mapping for use in GPS surveying and GIS post processing. The Ashtech Micro-Z stations will provide the primary high-accuracy reference for Shanghai. Ten of the sites are equipped with radios to broadcast RTK and DGPS messages throughout the Shanghai area to support high-accuracy real-time navigation, GIS and surveying needs.
The stations are also outfitted with Paroscientific Met3 Meteorological Stations, and both GPS and meteorological data will be collected and automatically forwarded every 30 minutes to a data processing center for scientific research. The goal of this research is to improve weather forecasting in the Shanghai region, which is prone to monsoon rains and flooding from May to September.
