In this work we have studied accuracy of GPS for tide gauge stability monitoring as well as possibilities for observing the absolute sea level rise of the Baltic Sea with GPS and tide gauge time series. Our determination give the average sea level rise for the long, up to 120 years, time series 1.9 ± 1.0 mm/year, and when corrected for the geoid rise, 1.6 ± 1.0 mm/year. Rates of recent years are even eight times higher. The possibility to detect minor changes in tide gauge benchmark height with GPS may be limited by GPS-related errors, which can be up to several mm even in a 10 km baseline.
