Opis:: The paper presents the results of investigations on the Hans glacier on Svalbard. The Artic conditions reąuired the application of a very specific surveying technology to make surveys of displacenients of an extensive and fast changing object. The technology that was implemented should combine observations made on extended areas (GPS) with classical observations of high precision. The SmartStation equipment which has been used to conduct the experiment of monitoring dynamie movements of a group of points situated on the Hans glacier fulfills this requirement. The surveys (quasi-continuous) were conducted in a period of three days. The paper contains the results of surveys as well.

Opis:: The analysis of the measurement results exemplifies very valuable information about the glacier behavior which glaciologists need to understand phenomena occurring on the glacier in different seasons. Beside the experiences collected during this experiment it will be the background to design similar investigations from survey technology and methodology point of view. Basing on these results and experiment analysis we can draw some conclusions: - In the period of the experiment the glacier surface felt down as much as 2 meters. This is the natural tendency and consequences of flowing down the glacier to the fiord and his ablation. - In the figures we could notice wavy nature of the phenomenon of the glacier surface which probably is connected with topography of the fiord bottom, ocean tides affected on the glacier front and some processes connected with the ablation water delivery to the glacier bed. This problem requires a detailed study based on environmental data. - The results of determined heights were periodically disrupted by atmospheric conditions (snowing, wind). - The GPS data used to follow the vertical velocity of the glacier surface let us to monitor the glacier with height accuracy. Also the automation of the survey and post-processing is possible. - There are some disadvantages of using this monitoring technology in surveys: one point of observations, influence of atmospheric conditions on the results of surveys, periodically hard access to equipment and not good enough way of installation of the satellite antenna on the glacier (ablation pole).

Opis:: Fast and exact GPS measurements are independent from weather and season of the year. For achieving reliable results, survey should be conducted at least once a month and at least twice a month in summer season (June-September). GPS RTK is suggested for pole movement determination. In case of real-time corrections limited availability (i.e. screening by mountains) using Rapid Static is a good choice. To minimize multipath error antenna should be placed at least 0,5m eccentric to pole and at 1 m height. Ablation pole movement vectors of Hans glacier indicate few relations. Most important feature is speed being about 10 times greater in foremost zone of glacier than in lateral parties of glacier. Measurements of lateral profile indicate that, accordingly to expectations, surface speed of glacier is greater in middle axis comparing to the edges or glacier.
