| Popis: | Comunicación presntada a la 3ª Asamblea Hispano-Portuguesa de Geodesia y Geofísica = 3ª Assembleia Luso-Espanhola de Geodesia e Geofisica, celebrada en Valencia entre el 4 y el 8 de febrero de 2002. The Institute of Astronomy and Geodesy (UCM-CSIC) has installed a GPS permanent station in the geodynamic complex of Jameos in Lanzarote. In this same place there are two automated tide gauges of precision (pressure sensors). With these instruments it is sought to study the sea level variations and their possible correlation with the GPS observations. For these studies it is absolutely necessary to have an altimetric link with high accuracy between the reference point of the pillar where the GPS antenna is installed and the tide gauges bench marks. We have carried out two observation campaigns in the years 2000 and 2001. Methods of repeated geometric levelling of very short tracts have been used due to the great existent level difference. The reciprocal and simultaneous trigonometric levelling has also been used that is adapted in this type of visual inclined. In this paper the works carried out in the two epochs with the putpose of making the altimetric connections before mentioned are described. The results obtained, the evaluation of the levelling campaigns, and the comparison of the levels of different measurements are also presented. |
