GPS geodetic satellite positioning receivers

Our office is equipped with the latest technology Geodetic GPS satellite positioning receivers THALES, Z-MAX which consists of two receivers of two frequencies GPS L1 + L2 with unique capabilities for RTK (Real Time Kinematic) applications, ie kinematic positioning (accuracy 1cm ) in real time.

The innovative technology of these receivers allows us to:

  • Determination of three-dimensional coordinates of network peaks which is particularly important as it provides the ability to measure or thicken an existing network from 1st to 5th order. The coordinates are determined with very high accuracy and refer to the Greek Geodetic Reference System 1987 (EGSA’87).
  • Compilation of topographic diagrams which are in accordance with the specifications and requirements of the forestry offices, the urban planning offices for the issuance of building permits, the Real Estate Service for the compilation of diagrams for the determination of Aegialos and Paralia.

Large-scale impressions in a minimum of time due to advanced technological equipment as well as impressions in inaccessible mountainous areas.

  • Engravings of complex or even simple curves but also thickening of lines. Especially in road construction projects (which are determined in coordinates EGSA’87) there is the possibility of drawing at distances that reach even 50 Km. This is done with the advanced communication system (UHF Radio Link 4 w system and backup communication system of the receivers via cosmote gsm – data – fax mobile network). With this system the receivers communicate with each other at a distance of 50 km without changing position.
  • Capturing successive layers of materials over large areas and distances to calculate the volumes of earthworks offering savings in the cost of topographic work.
  • Impression and engraving of points without visual contact between the receivers (rover – base) in contrast to the conventional topographic methods of geodetic stations (total station – light).
  • High productivity at low cost. Specifically, the capabilities of the Z-Max RTK system in capture reach 2000-3000 points per eight hours, while up to 1000 points per eight hours can be drawn by a workshop (surveyor + 2 assistants)!
  • Imaging of photostables in a short time and at low cost.

What is GPS?

For the first time since March 12, 2013, the new group of satellites Galileo . The European Positioning System has been developed by the European Space Agency (ESA).
So far the system is operating on a trial basis with only four satellites but in the future its number will increase to thirty.
