In many work locations, just a few GPS and GLONASS satellites may be visible due to obstacles such as trees or buildings.

Z-Blade allows users to receive and maintain RTK positioning even if GPS coverage is insufficient. Z-Blade uses all of the available satellite signals equally, without preference to any particular satellite constellation, maximizing the user’s ability to obtain reliable GNSS positions in tough conditions. Z-Blade is a new GNSS centric signal processing technology. Automatic sessions programming, a user-friendly Web-interface, an embedded RINEX converter, FTP push functionality and many other advanced CORS features make the ProFlex 800 CORS a powerful, robust and easy-to-use GNSS solution. The Spectra Precision ProFlex 800 is also available as a Continuously Operating Reference Station (CORS).This configuration is an optimal solution when collecting, storing and transferring high-quality GNSS raw data for post processing surveys, geodetic and other applications. Spectra Precision ProFlex 800 CORS Receiver This capability allows instant real-time multi-data streaming over an Ethernet connection to build an RTK corrections server without any additional software or equipment. With its built-in Ethernet capability and embedded Web Server, users can access the ProFlex 800 from any computer connected to the Internet. Its Z-Blade long-range RTK capability combined with industry-leading UHF options help to ensure maximum productivity while in the field. It can be used as a rover or a base without additional accessories in the field. In addition to a 3.5G internal cellular modem, the ProFlex 800 can use a variety of internal or external UHF modules, providing stable and reliable wireless communications. The weatherproof, high-impact-resistant molded aluminum housing allows the ProxFlex 800 to operate in harsh conditions. Its innovative design also makes it ideal for hard mounted survey applications such as coastal work, dredging, bathymetry or offshore vessel operations. Used as a backpack rover or reference station, the ProFlex 800 with Z-Blade technology is a flexible GNSS solution for land surveying. 'It offers a unique design with a range of mounting and communications options.' 'The ProFlex 800 is an ideal solution for customers wanting a single GNSS receiver for multiple applications,' said François Erceau, general manager of Trimble’s Spectra Precision, Nikon and Ashtech Business Area. Rugged and IP67 rated, the ProFlex 800 is built to withstand harsh operating conditions for a variety of positioning applications. The ProFlex 800 delivers fast and reliable RTK positioning, even in environments where GNSS signals may be difficult to acquire.

Westminster, Colo., April 2, 2012-Spectra Precision introduced today the new ProFlex™ 800, a powerful GNSS solution with revolutionary Z-Blade™ GNSS-centric technology.
