Founded in 2006, Altus Positioning Systems provides a portfolio of affordable high-precision GNSS RTK surveying instruments for the international surveying and GIS marketplace. For 2013, Altus is broadening its product line with new GNSS receivers designed to use real-time L-band satellite precise point positioning service without a base station in areas where GSM and radio RTK is not available. Altus receivers operate with leading third-party data logging software and interface with ESRI databases for GIS applications.
