The Finnish-Hungarian Doppler Observation Campaign was carried out in Finland in Aug. 1983 during 13 days. The campaign was organized by the Finnish Geodetic Institute with financial and manpower support of field work. Three Hungarian JMR-1A receivers and one Finnish JMR-4 occupied 9 stations together with the 1st order triangulation network points of Finland. The data processing was performed in SGO, Penc. The observation strategy, the methods of data processing and results obtained by GEODOP and SADOSA programs as well as the S-transformations are presented in this paper.
In May 1980, the WEDOC-1 was carried out covering 14 simultaneous stations and establishing a first link between observatories in Western and Eastern Europe. In order to improve the results of WEDOC-1 using a better station configuration and refined software and calibration techniques a second campaign WEDOC-2 was initiated by Graz (Austria) and Penc (Hungary). The configuration comprized 27 stations in 18 countries which carried out simultaneous Doppler observations from September 6th to 16th, 1983. Four different calibration campaigns were used to estimate receiver and program biases. Station coordinates have been computed by means of the programs GEODOP in Graz and SADOSA in Budapest. and V maje 1980 g. byla osuščestvlena kampanija "WEDOC-1", v kotoruju vključilos' 14 stancij. Vpervyje osuščestvlena privjazka meždu observatorijami Zapadnoj i Vostočnoj Jevropy. Čtoby ulučšit' rezul'taty kampanii "WEDOC-1" vtoraja kampanija "WEDOC-2" byla osuščestvlena observatorijami Grac (Avstrija) i Penc (Vengrija) s ulučšennoj konfiguracijej stancij, ulučšennym obespečenijem i technikoj kalibrovki. Konfiguracija vključila 27 stancij v 18 stranach, kotoryje vypolnili sinchronnyje nabljudenija s 6 - 16 sentjabrja 1983 g. Primenili četyre raznych kampanii kalibrovki, čtoby ocenit' pograšnosti prijemnika i vyčislitelnoj programmy. Koordinaty stancij byli vyčisleny s pomošč'ju programm GEODOP v Grace i SADOSA v Budapešte.
