Mobile Mapping With The ProMark 3 RTK... High Precision Without High Cost
Written by Glenn Letham (GISuser)
Tuesday, 08 May 2007
Are you heading out to te field? The Magellan ProMark(TM) 3 RTK offers complete real-time GNSS surveying and mobile mapping. Sporting a new GNSS engine, BLADE technology delivers centimeter accuracy for real-time and post-processing surveys and mapping operations.
BLADE’s unique GPS+SBAS RTK algorithm ensures quick initialization with single frequency receivers and takes full advantage of the maximum satellite coverage from the dual constellation. Benefits to the user include: easy-to-use, easy-to-learn technology, rugged design, reliable connectivity, precision performance, and affordability.
Features:
The integrated radios conform to the IP65 standard and are directly powered from the receiver and easily configured through a simple menu.
ProMark3 RTK can be used as a rover only, connected to a real-time network. A Bluetooth connection can be established between ProMark3 RTK and a cellular phone.
ProMark3 RTK is compatible with NTRIP and direct IP and can be connected to any GPS network broadcasting corrections (RTCM 2.3, RTCM 3.1).
As with the original ProMark3 receiver, post-processing features are included in ProMark3 RTK. Raw data, simultaneously recorded during RTK jobs, can also be post-processed via the GNSS solutions office software for superior survey integrity. Post-processing ensures full control of the quality of the data collected.
ProMark3 RTK enables you to take any supported GIS file into the field. Easily navigate to field infrastructure for reckon and mapping. Update your GIS data and transfer the file back to the office GIS for the customer.
In mapping mode, ProMark3 RTK delivers decimeter to centimeter-accurate positioning.
Real-time features are fully compatible with previous version of ProMark3.
Optional FAST Survey includes topographic features typically associated with dual-frequency. These easy-to-use features make it possible for professional surveyors and novice GPS users alike to run complete survey jobs, including stake out, and combining projects done in association with total stations
For the GISuser & Mapping Professional
MobilMapper™ Office software links the ProMark3 RTK receiver to the GIS database. Simply upload shape files and other GIS data to be updated in the field. Editing data and exporting .SHP, .MIF, .DXF and .CSV files is easy.
GIS Data Post-Processing - ProMark3 RTK is a mobile mapping system with full GIS data collection and navigation software. MobileMapper™ Office software links the receiver to the GIS base and provides convenient features such as: - Quick and easy editing and exporting of data. Includes support for .SHP, .MIF, .DXF and .CSV files - Uploading or creation of vector background maps for use in the field - Raster image support - Post-processing
About BLADE(TM) Processing: In the DG14 RTK, BLADE, Magellan’s new proprietary GNSS processing technology, uniquely incorporates ranging and carrier phase signals from satellite-based augmentation systems (SBAS), such as WAAS, EGNOS & MSAS in the RTK computation.
