Spectra Precision recently introduced the new ProMark GNSS receivers. The new ProMark 120 and ProMark 220 GNSS receivers, powered by Ashtech, provide surveyors with an expanded set of capabilities and enhancements, and replace the ProMark 100 and ProMark 200.

The announcement was made at Spectra Precision’s Worldwide Distribution Conference held in Hannover, Germany. The expanded product portfolio will be showcased at INTERGEO 2012, the world’s largest geodesy, geoinformatics and land management trade event.

Both new ProMark models are equipped with an updated hardware platform that includes the latest Ashtech GNSS chipset with Z-Blade GNSS-centric technology. In addition, both come with the Microsoft Windows Embedded Handheld 6.5 Professional operating system.

The new ProMark 120 features enhanced ProMark Field software v3.0, which introduces a large, custom virtual keyboard; enables the import and export of user-defined text file formats; enhances voice information and guidance features; among other improvements.

The dual-frequency and dual constellation ProMark 220 RTK Rover also features an internal L2 GLONASS receiver. Its Z-Blade GNSS-centric firmware provides exceptionally fast RTK initialisation and more reliable RTK positioning, specifically in shaded or multipath conditions, where GNSS signals may be difficult to acquire.

The ProMark 220 is offered with a choice of advanced field software applications: either the Survey Pro v5.2 or the FAST Survey v3.0 software. Additional software options allow interaction with a wide range of survey instruments and accessories to run complete survey jobs and survey projects where total stations are also used.

“With unique positioning capabilities and robust features, both new ProMark receivers are ideal tools for surveyors looking for a cost-effective, high performance and reliable solution,” said François Erceau, general manager of Trimble’s Spectra Precision Surveying Business.
