ProMark 120
The Spectra Precision ProMark™ 120 GNSS system is the most versatile post-processing solution, designed for easy and efficient land survey applications. Thanks to the embedded Ashtech Z-Blade technology as well as GPS and GLONASS signals tracking, ProMark 120 provides high-precision measurements even in very demanding or obstructed environments. The very intuitive ProMark Field software is designed for simple and trouble-free use. It provides all the tools you need, without any unnecessary or complicated features. Its lightweight, but rugged and waterproof handheld design, all-day-long autonomy, and large memory make ProMark 120 the perfect solution for easy and efficient surveying. Designed as a scalable solution, ProMark 120 can be easily upgraded to such capabilities as GLONASS,RTK or GPRS and be used not only in post-processing but also in RTK or GIS applications. Built on the state-of the-art Windows Embedded Handheld 6.5 platform with integrated wireless communications, ProMark 120 is a truly versatile and complete offering



ProMark Field Software
Easy-to-use and very intuitive, ProMark Field software is designed
for simple and trouble-free use of the ProMark 120. It provides
all necessary tools for efficient post-processing survey as well as
simple RTK jobs, including raw data recording, rover and base
configurations, static or kinematic surveys, network connection
settings, or stake out. ProMark Field software brings to ProMark
120 users a simple but powerful tool, without any unnecessary or
complicated features.
Spectra Precision Survey Office Software
Spectra Precision Survey Office software is ideal for processing
and analyzing GNSS survey data recorded in the field. With Spectra
Precision Survey Office software you have the ability to work with RTK
and Static/PPK data to generate reports as well as identify and correct
field errors. The intuitive, integrated Spectra Precision Survey Office
program saves time with its short learning curve and powerful features.

(*) Including all available options
(1) Accuracy and initialization specifications may be affected by atmospheric conditions, signal multipath, satellite geometry and corrections availability and quality. Position accuracy specifications are for horizontal positioning. Vertical error is typically < 2 times horizontal error.
(2) Performance values assume a minimum of five satellites and following the procedures recommended in the product manual. High multipath areas, high PDOP values and periods of sever atmospheric conditions may degrade performance.
(3) Steady state value for baselines < 50 km after sufficient convergence time.
(4) No BT or WLAN are used, backlight at default setting (50% brightness), varies with temperature.
(5) Optional upgrade to ProMark 220.
