  4. NRT session: EUMETSAT GPS Orbit

  5. NRT session: EUMETSAT GPS orbit • Short Report available: • Near Real-Time Precise Orbit Determination for Radio Occultation and Altimetry Missions • Y. Andrés, P.L. Righetti, C. Marquardt, EUMETSAT, Darmstadt Germany • Data available on request

  6. Jason-1 End-Of-Life Orbit Selection • The incentives for a geodetic/new-repeat orbit • Improved geoid & MSS with Jason-1 high-precision/low inclination orbit • Unique opportunity for new geodetic science from last research mission • Minimal impact to NRT wind/wave applications • The incentives for remaining in the Topex/Jason orbit • Optimal mesoscale sampling with current interleaved + reference orbit • SSHA errors from mean profile < errors from gridded MSS • Needed until Altikais operational because of new Envisat orbit • Consider the scientific impacts to NRT applications

  7. Jason-CS Reference Orbit Selection • The incentives for a lower/different orbit • Potential reduction in launch cost • Potential extended lifetime due to decreased radiation • Potential improved instrument performance • Better prospects for orbital debris mitigation • Better high-latitude coverage • The incentives for remaining in the Topex/Jason orbit • Improved capability for the inter-calibration between Jason-3 and Jason-CS required to maintain the climate record of sea level • High-latitude, as well as mesoscale sampling, can be provided by other altimeters in the OST Constellation • Orbital debris at 1336-km is less a threat than at lower orbits • Consider the scientific impacts to NRT applications
