Russian Company Credo-Dialogue Releases GNSS Software

March 18, 2015By

The Russian company Credo-Dialogue has released Credo GNSS 1.0, a GNSS processing software. Credo GNSS 1.0 is designed for processing of satellite geodetic measurements in differential mode. In this mode, the simultaneous operation of two or more receivers forms the baseline. The input can use the following types of data: satellite geodetic measurements and ephemeris format RINEX (2.0-3.2); satellite geodetic measurements and ephemeris formats... read more
