Malechaux and S. Coutin-Faye, CNES Subject: No 0468 : Current Jason-1 SHM Recovery Status JASON-1 SHM STATUS, Wednesday, Nov. 15 th, 18:00 UTC SHM investigation status: The analysis of the Jason-1 Housekeeping Telemetry before and just after the SHM confirms that the only problem encountered by the spacecraft is a double EDAC error in the onboard software RAM due to a very aggressive environment at this moment (fly by of the South Anomaly Atlantic). Numerous EDAC errors were also detected by the scrubbing task of the Mass Memory. SHM recovery operation plan: Today, after a successful remapping of the Mass Memory modules, SHM recovery operations have been able to start. The corresponding main steps are the following: 1. DORIS set in operation (performed on November, 15th, 12:57 UTC) 2. Switch on and check of each PROTEUS equipment: a. Gyros: performed, status OK b. Star Trackers: performed, status OK c. reaction wheel No.3: to be performed during the night of 15 to 16 Nov. 3. Star aquisition mode transition: to be performed during the night of 15 to 16 Nov. 4. GPS set in operation: to be performed during the night of 15 to 16 Nov. 5. Earth pointing mode transition: to be performed on the 16th 6. Nominal operational mode transition: to be performed on the 16th 7. POSEIDON set operational: to be performed during the night of 16 to 17th Nov. 8. JMR set operational: to be performed on the 17th 9. Return to mission routine activities with JPL: to be performed on the 17th evening 10. TRSR set operational: to be performed on the 20th by JPL Next status: Thursday, 16th, 19h UTC N. Malechaux and S.
