  • The Trimble R-Track\u2122 technology;<\/li>
  • The advanced GNSS-chip, which is named as TrimbleMaxwell\u2122 5 CustomSurvey and equipped with 72 channels;<\/li>
  • The high-accuracy multiple correlators for measuring the GNSS pseudo-ranges;<\/li>
  • Measurements of GNSS phases of carrier frequencies, which are notable for very low noise level and accuracy <1 mm in the frequency range of 1 Hz;<\/li>
  • The signal-noise relation is indicated in dB and Hz;<\/li>
  • The Trimble field-approved technology for tracking satellites with small angle of elevation;<\/li>
  • Capability to track signals of satellites simultaneously.<\/li><\/ul>","protected":false},"excerpt":{"rendered":"

    The Trimble R-4 GPS receiver uses proven GPS technology solutions, operates at L1 and L2 frequencies, and can be upgraded to receive signals from GLONASS if necessary. The accuracy of the results is achieved by the installed dual-frequency antenna, which allows you to track signals from satellites.<\/p>","protected":false},"featured_media":550,"template":"","technology_type":[33],"yoast_head":"\n\u0414\u0432\u043e\u0447\u0430\u0441\u0442\u043e\u0442\u043d\u0438\u0439 GPS-\u043f\u0440\u0438\u0439\u043c\u0430\u0447 Trimble R-4 -
