FEATURES

  • The only sub-meter integrated hand-held GPS/GIS receiver on the market.
  • Very good for precision farming, hydrographic surveys, etc.
  • Signal inaccuracies are removed with RAIM (Receiver Autonomous Integrity Monitor). Built-in strobe correlator technology provides unmatched multi-path mitigation for code.

The Alto-G12 package included CMT's PC-GPS software for comprehensive GPS project management and mapping. PC-GPS 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) and Microsoft® ODBC.
