KEY WORDS: GPS, navigation, surveying, monitoring, method, dynamic. Abstract GPS data collection started at Terra Nova Bay Station (Antarctica) since the 1988-89 in the framework of the Italian Antarctic Research Program (PNRA). During the past expeditions a number of tests of GPS kinematic were made. The GPS data were collected under various operational conditions and for different targets, such as glacier movements monitoring, kinematic GPS controlled aerophotogrammetry, execution of long range Antarctic traverses, ship navigation tracking control, etc. Those GPS kinematic applications showed peculiar aspects by the point of view of data processing, due to ionospheric disturbances and satellite configuration at high latitude. Here are described the different kinematic GPS experiences and are presented some results. 1. Introduction The very high ionospheric disturbance and the NAVSTAR GPS constellation characterised by low satellite elevation, create serious problems in signal acquisition and data processing. The strong influence of the severe ionospheric conditions became evident during GPS static data elaboration. This effect has been overcame through the employment of idoneous post processing strategies, and receivers 31 development. On the contrary, the problem, still maintains problematic aspects for kinematic applications, so in order to obtained the required precision it is not possible to apply an automatic procedure, but it is necessary to analyse step by step limited block of data. Various applications required different levels of accuracy and precision, ranging from different tens of metres for navigation purposes to few centimetres for glacier bodies monitoring through profiles comparison. Precision of few metres level are achievable without serious problems using code smoothing techniques also in Antarctica, the critical aspects pointed out for high accuracy applications where the presence of ionospheric cycle slips often invalidate fixed ambiguities determination. This aspect becomes evident already after a distance of 5 km between master and rover receiver (Vittuari, 1994). 2. Airborne kinematic GPS positioning Different application for GPS assisted aerophotogrammetry and geophysical survey purposes were made in Antarctica. In this case the required accuracy is related to the purposes of the survey and ranging from few metres to few decimetres.
