ESA Meeting with Hungary
Les detecteurs des 4 instruments destines i l’etude des sursauts gamma (Konus, Phebus, Toumesol, Watch) sont repartis sur l’ensemble de la plateforme, de facon a observer toute la sphere celeste dans un domaine d’energie allant de 2 keV a 100 MeV. Le nombre de sursauts cosmiques detect& par an sera de l’ordre de la centaine. Les sursauts arrivant dans le champ des telescopes seront local&% avec une precision de 1 minute d’art, ce qui devrait enfin permettre leur identification a des objets comms. La charge utile est le fruit dune cooperation entre 1’Union Sovietique, la France, la Bulgarie et le Danemark. La France a fourni le telescope Sigma, les detecteurs de sursauts gamma Phebus, la memoire de 128 Mbits, le systeme de restitution d’attitude du telescope, le systeme de commande des Cquipements scientifiques et un Cquipement de test et de controle. Le telescope Sigma, d’une envergure sans precedent dans le domaine de l’imagerie gamma (poids: 1 tonne, hauteur: 350 m diametre a la base: 1,20 m) est constitue d’un masque code et dun detecteur de position. 11a Cte developpi sous la maitrise d’oeuvre du CNES a Toulouse, en collaboration avec deux laboratoires scientifiques: le Centre d’Etude Spatiale des Rayonnements (CESR) du CNRS et le Service clAstrophysique du CEA. L’instrument Phebus a ete realid par le CESR. Quatorze societes industrielles ont participe a ce programme, dont Sextant Avionique, Latecobre, Matra, Sodem, Sagem. Apres une recette en vol du satellite, les premieres images gamma du ciel devraient parve& au debut du mois de janvier 1990. Le traitement et l’exploitation des donnees seront effectues, du c&e francais, par le Centre Spatial de Toulouse et les experimentateurs des laboratoires.
5.12. ESA MEETING WITH HUNGARY’=’
Following previous contacts and exchange of letters, a formal meeting took place on 16 and 17 May 1990 at ESA Headquarters between a delegation of the Republic of Hungary, headed by Professor Ferenc Marta, President of the Hungarian Intercosmos Council and a delegation of ESA, headed by Professor Reimar Liist, Director General. The heads of the two delegations summarized the long and successful cooperation existing between the Parties and expressed the wish to develop further the cooperation on space research between Hungary and ESA. The two delegations exchanged information on the existing activities and prospects of future cooperation in the fields of: Space Sciences Earth Observation Microgravity Telecommunications f'*)FromESA

The Hungarian delegation expressed the hope that a cooperative agreement could be concluded in the near future which would pave the way for a closer association with ESA’s activities and reintroduce Hungary to the European commtmity in space activities. The ESA delegation welcomed the wish expressed and offered its best efforts to work to this end. The next meeting between the two delegations will take place in Budapest in July 1990.
5.13.CRITICALDESIGNREVIEWOF 5ARl-HRESOURCESSATELLITE-1 WI
A critical design review (CDR) of the Earth Resources Satellite-l (ERS-1) took place on 13 and 14 July 1989. The results of the modification associated with changes in the system design base-line (such as change of local time in passing the descending node), and of system development research tests using system engineering and thermal structural models were reflected in the CDR. Since equipment needed for the ERS-1 mission (e.g., synthetic aperture radar, optical sensors, mission data transmitter, and mission data recorder) is being developed by the Japan Resources Observation System Organization (JAROS) of the Ministry of International Trade and Industry (MITT), the interface between the main body of the satellite and mission equipment was reviewed in the presence of MITI/JAROS personnel. The review confirmed the validity of the system design, and the design of the ERS-1 proto-flight model (PFM) was established. Since the ERS-1 onboard equipment had already undergone a critical design review, fabrication and tests aiming at completing the PFM system are under way. The PFM of the ERS-1 system, based on the CDR results is scheduled to be assembled by July 1990. ERS-1 will be launched in the winter of 1991 after completing proto-flight system tests (electric performance tests and various environmental tests) at Tsukuba Space Center to verify the functions and performance of the satellite. These tests are expected to last for more than a year.
