The DA2 is the Next generation Trimble Catalyst (L1/L2/L5) GNSS RTK receiver which delivers survey-quality GNSS positioning to location-enabled Android phone. Cable Route tracing of Medium to Long Distance Cable routes with simultaneous acquisition of GNSS coordinates with High Accuracy of up to 5cms (Or 60 cms based on RTX correction service selected), Cable Depth Data & Asset Images.
The Terra Flow Utility Mapper Mobile App can be installed on any dual Bluetooth android mobile phone & connects to both the Pathfinder PLDL Cable Route tracer & the DA2 GNSS Receiver. Mobile App fetches data acquired includes Route traced, GNSS coordinates of route, Depth data, GNSS error, Date/time of trace acquired and synchronized through cloud with Map data generated automatically for viewing or downloading in office. Data collected in field is Automatically updated to server & Maps can be downloaded in office in real time without further need for emails, file sharing etc.
Digital Maps created Automatically with no further human intervention required. Access GNSS coordinates of cable route with depth & images. Data can be downloaded in. kml (Pictorial map in google earth), AutoCAD, .shp (Shape files) or download data logs in .csv (including Date/time of route trace). It is also possible to add sketches to existing maps for project planning.
The Pathfinder PLDL is the ideal solution for creating Digitized maps of existing cables & pipe routes with pictorial view maps & images.
