    Principles of Operation channels can be used to track any one of the GPS or GLONASS signals. The number of channels available allows the receiver to track all visible GPS and Glonass satellites at any time and location. An internal GPS+GLONASS L1 antenna equipped with a low noise amplifier (LNA) and the receiver’s radio frequency (RF) device are connected with a coaxial cable.

  • Page 19: Calculating Differential Positions

    Principles of Operation Calculating Differential Positions DGPS, or Differential GPS, typically uses the measurements from two or more remote receivers to calculate the difference (corrections) between measurements, thus providing more accurate position solutions. With DGPS, one receiver is placed at a known, surveyed location and is referred to as the reference receiver or base station.
