Abstract. During long term experimental works of GPS measurements carried out for stationary points on the Earth’s surface in the DGPS regime, the methodical errors in the altitude data were revealed. The experiments were conducted with the aim to assess potential GPS navigation possibilities to register the altitude of the underlying Earth surface position varying due to lunar-solar tides. Experiments were carried out during several months. Every continuous measurement data record lasted 14 days. The obtained results explain and confirm the absence of potential possibility to image vertical movements of the Earth’s surface due to lunar-solar tidal observations at North-West of the Eurasian continent in accordance to GPS receiver data. The method of the methodical errors of altitude data survey detection and partial elimination was submitted.

Keywords: gravimetry, long term tidal gravimetric observations, geodynamic movements, vertical and horizontal channels of GPS measurements, the errors of high frequency vertical and horizontal movements measurements by GPS receiver.
