Dual-frequency GPS
Model CMT Z33


The CMT Z33 package includes CMT's PC-GPS 4.X software for comprehensive GPS project management and mapping. PC-GPS 4.X provides functions for mapping, Mission Planning, Batch Differential Correction, Static Point "Spread" analysis and Job Editing.

The software also supports GIS layering, raster images (i.e. DOQs, DRGs, aerial photographs, satellite imagery), multimedia objects (OLE 2.0), Microsoft® ODBC and extensive Coordinate Geometry (COGO) functions.
