Overview for the Ashtech ProMark 120 Receiver with L1/L2 GPS

The Ashtech ProMark 120 GNSS Receiver from Spectra allows professional surveyors to accurately map survey sites with 1 centimeter accuracy and  extended range for efficient survey, RTK and even GIS applications. With expanded GNSS enhancements from the previous model (ProMark 100), this survey grade GPS package includes an external ASH661 L1/L2 antenna, on-board ProMark field software, a Windows Handheld 6.5 operating system and upgradeable options such as NTRIP/Direct IP and RTK. 

On Board Z-Blade Technology

With the embedded Ashtech Z-Blade technology on board the ProMark 120 receiver, both GPS and GLONASS satellites are utilized to obtain a more reliable GNSS position in obstructed survey sites. In addition, this Spectra-exclusive technology makes it possible for the GPS receiver to get a real time kinematic (RTK) fix even if the GPS satellites are out of range.  

Long-range Accuracy

With the included ASH661 L1/L2 antenna of this ProMark 120 kit, the device can obtain a real time fix with 1 cm accuracy in as fast as 15 seconds with a typical range of up to 25 miles. 

ProMark Field Software

The ProMark Field software 3.0 that comes with the ProMark 120 provides all the necessary tools for post-processing and analyzing GNSS survey data, as well as simple real time kinematics (RTK) jobs, such as raw data recording, rover and base configurations and stake out. 

Reliable Windows Platform

With the Windows Mobile 6.5 operating system, the ProMark 120 GNSS receiver  supports 10 different languages and performs survey tasks using familiar software packages such as GNSS Toolbox, ActiveSync and Internet Explorer. In addition to wireless GPRS and Bluetooth connectivity, this survey GPS has a large built-in 256 MB memory, expandable up to 2 GB. 

Designed for Durability

The Ashtech ProMark 120 GPS unit is dustproof and water resistant with an IP 65 protection rating. In addition to being lightweight and rugged, the surveying device has a built-in 3 megapixel camera, E-Compass, microphone and speaker. The ProMark GPS also features a high-resolution alphanumeric touchscreen keyboard.

With the 1 cm accuracy and versatility of the Ashtech ProMark 120 and extended range of the included ASH661 L1/L2 GPS antenna, the ProMark 120 is easily one of the most versatile surveying GPS units  for both advanced and novice land surveyors.
