The Ashtech ProMark 220 Dual Frequency GPS Receiver from Spectra provides surveyors with expanded capabilities for versatile GNSS survey applications. It has the same hardware receiver as the Ashtech ProMark 120 and even the Mobile Mapper 120 but with expanded software packages, accessories and loaded GNSS applications, such as RTK, NTRIP/DIP and GLONASS, as well as a dual frequency ASH661 antenna, enabling it to be used as an accurate and cost-effective network rover.
Ashtech Z-Blade Technology and RTK
The Ashtech Z-Blade technology on the ProMark 220 utilizes both the GPS (US) and GLONASS (Russian) dual frequency satellites for more reliable GNSS positioning in survey sites with obstructed views or canopies. Combined with the L1 and L2 antenna, this Spectra-exclusive technology increases accuracy and allows the device to get a real time kinematic (RTK) fix even when no GPS satellite is available. The increased positioning accuracy of the network RTK rover allows for faster and more reliable site mapping.
Accurate Survey Receiver
The ProMark 220 is a great network rover that can get a fix in as fast as 15 seconds. Its 0.4 inch real time accuracy is comparable to higher-end GNSS receiver, such as the ProMark 800. With the included ASH661 dual frequency antenna, the ProMark 220 has a typical range of almost 25 miles with a reading reliability of 99.9%.
Microsoft Windows Embedded OS
Along with built-in wireless connectivity, the ProMark 220 has a 256MB memory expandable to 2GB and comes with a Microsoft Windows Embedded Handheld 6.5 operating system, supporting 10 different languages. This operating system also comes with familiar programs, including Internet Explorer, Microsoft Office Mobile, GNSS Toolbox, Transcriber (a handwriting recognition tool), ActiveSync and more.
The Ashtech ProMark 220 has a rugged yet lightweight handheld design. It is dustproof and water resistant with an IP 65 protection rating. The GNSS device has a 3 megapixel camera, E-Compass and a built-in microphone and speaker.
Spectra Survey Pro Field Software
The Spectra Precision Survey Pro Field Software on the ProMark 220 provides you with a complete set of capabilities for all your survey application needs. This survey software supports your GPS instrument, fast data collection and PC transfer, as well as advanced stake out solutions.
As an upgrade from the ProMark 200, the Ashtech ProMark 220 allows for cost-effective and accurate GNSS applications using an updated operating system, Spectra’s exclusive Z-Blade GNSS-Centric Engine and the ability to track locations using GLONASS satellites.
