Maritime Differential GPS systems (283.5-325 kHz) are today the basic method for determining the position of vessels in coastal navigation, entering into seaports as well as pilotage around the world. Today, the position accuracy of these systems reaches about 1 m (p = 0.95) and its availability is higher than 99%. In the last decade, many countries, including Poland, have created a number of national and commercial GNSS geodetic networks. Their range often also includes marine waters, hence the use of methods of ...

Decisions related to the choice of investment site selection, made by government administration bodies, have a major impact on the economy in the region. They can cause economic growth or may cause slowing down its development. To avoid or at least minimize the negative effects of investment decisions, they should be taken on the basis of analyzes carried out earlier. Conducting an analysis related to indication the site selection for a given investment object requires obtaining information covering various spatia...

In the era of dynamically changing business environment, planning in an enterprise is a part of decision making process. Therefore, a good prepared action plan is necessary. The rationality of decisions included in the plan depends on the quantity and quality of information available to the decision maker. Enterprises, including coal mines, are a set of interdependent phenomena. For that, we need to create decision support tools, the results of which will be visible in the future.
