It seems that the anomaly was due to a Single Event Upset on DORIS internal= communication component, and was cleared by the restart. POSEIDON measurements will be available right after the coming pass at 10:1= 1UTC. However, due to a required convergence process on DORIS, OGDRs will n= ot be available before tomorrow (Friday Oct. 30th), around 11:00UTC. As a reminder, those OGDRs will be provided in standard-F as expected (cycl= e 174). Very best regards, Christophe Marechal / CNES JASON-3 project manager, on behalf 4P project ma= nagers, at EUMETSAT, NOAA, and JPL.
