In the age of modern technologies, geodesy – as a science and a field of engineering life – has not remained neutral. At the turn of the recent years, a great revolution has taken place in the field of surveying techniques (GPS technologies, technologies of surveys without reflectors of hard-to-reach obstacles). The methods of map production and visualisation of natural phenomena have been developing along with the increase of calculation and technological potentials of computer-based equipment.
At present – thanks to lifting of disturbances in satellite systems for civilian purposes (e.g. Navstar system) – the GPS technologies are becoming more and more friendly and competitive in comparison to the classical methods. The concept of a dynamic network is nowadays not only the field of scientific notions. Dynamic networks become to be an everyday life issue. The GPS system – as one of the methods of satellite surveys – allows for execution of a survey in any place on the Earth, in any time of day and night, within a freely defined system of co-ordinates in a real time. Increase in the number of satellites in next systems (Glonas, Galileo, …) causes that the initialisation time in RTK methods is significantly minimised, and the static methods have got additional indeterminacy solutions, which improves and increases the strength of established geodetic networks and provides much greater possibilities in the field of accuracy analyses of networks.
The Polish geodesy is on the verge of new technological and organisational era (joining the European Union), has got a great chance and is just committed to cultivating the good tradition of Polish technical thinking, which has been always appreciated all over the world.Ignoring of the already proven systems (digital map, dynamic networks) that have proved to be useful in highly developed countries for years, would put us in an out-of-the-way locality of other countries that have admired us in many cases and derived from the achievements of our science (laser, gravimetric equipment, superconductors, …).
