Gravity Measurements in Panama with the IMGC-02 Transportable Absolute Gravimeter

The work hereafter described was designed to determine the gravity datum at the Centro Nacional de Metrologìa de Panamà CENAMEP AIP through absolute measurement of the gravity acceleration, and settle a gravity network in Panama. Twelve gravity station points were settled. Gravity data were collected with the transportable absolute ballistic gravimeter IMGC-02, operated by a team of the Istituto Nazionale di Ricerca Metrologica INRIM, in cooperation with the CENAMEP AIP and the Instituto Geográfico Nacional “Tommy Guardia” IGNTG. Establishment of the gravity net in Panama, with the highest accuracy currently obtainable, will help in the realization of primary standards and in the definition of the geodetic reference level. Moreover the gravity net may serve as reference for further detailed surveys and detection of long-term, time-dependent gravity variations.
