      Jason-3 DORIS instrument provides real time ephemeris

      2016-01-19

      The DIODE software onboard Jason-3 DORIS instrument provides real time ephemeris since yesterday around noon. The data quality was impacted by the satellite attitude law (so-called barbecue) but since today Jason-3 is using a nominal pointing law which allows to reach good accuracy as depicted on the DIODE navigator quality index.

      Jason-3 Launch Timeline

      2016-01-17

      About 154 seconds after the Falcon-9 rocket lifts off, the main engine will cut off. About three seconds after that, the rocket's first stage will separate. Second-stage ignition will follow in about eight seconds. Half a minute into the second-stage burn, the payload fairing, or launch vehicle nose cone, will be jettisoned -- a bit over three minutes after launch. The first cutoff of the second-stage engine will take place nine minutes after liftoff. The Jason-3 spacecraft and second stage wil...

      2016-01-17

      During a Jan. 15 briefing on NASA Television, panelists gave an overview of the Jason-3 mission – scheduled to launch on Jan. 17 from Vandenberg Air Force Base in California. Jason-3 is the newest in a series of satellites designed to maintain long-term satellite altimetry observations of global sea surface height. During its mission -- planned to last at least three years, with a goal of five years – the satellite will monitor and precisely measure global sea surface heights, monitor the in...
