Satellite equipment "IZYSKANIE"
Полное описание

"Izyskanie", a two-frequency satellite navigation equipment of the global navigation satellite systems (GNSS) is designed to provide topographic and geodetic surveying, special construction and monitoring of the Earth's surface.

The equipment "Izyskanie" can be used in combination with a geodetic control-correcting station when conducting geodetic work for high-precision determination of coordinates of points on the earth's surface in real-time and post-processing modes.

The "Izyskanie" apparatus provides definition of coordinates of points of a terrestrial surface:

  • in real-time mode by using corrective information transmitted over the GSM channel from a control-correcting station;
  • in measurements post-processing mode by using information obtained from a control-correcting station or other geodetic receivers.

The equipment is designed to maximize the effectiveness of static and dynamic surveys and can be used for a variety of purposes, such as:

  • geodetic reference;
  • grid creation and densification;
  • building;
  • land surveying work;
  • engineering survey;
  • topographic survey;
  • land demarcation;
  • land cadastre and more.
