Concept information
Preferred term
NASA/JPL/TOPEX
Definition
- TOPEX/Poseidon (T/P) was an altimetric mission jointly collaborated by NASA and CNES (French space agency). It launched 10 August 1992 and began data collection on 25 September 1992. T/P operated until 18 October 2005 and collected 481 cycles of data. T/P was capable of measuring significant wave height, sigma naught (sigma0), dry and wet troposphere and ionosphere, which can be used to calculate sea surface height and anomalies and total electron content. T/P had a repeat period of approximately 10 days with 254 passes per cycle. T/P began a drift maneuver 15 August 2002 cycle 365 pass 111 and ended 16 September 2002 cycle 368 pass 171. During this time T/P moved to a different orbit so that T/P and Jason-1 (which remained on the original T/P orbit) would survey the Earth in a shorter amount of time and give a higher spatial resolution. Lists of cycle start times, maneuvers performed to maintain orbit, sateholds and periods of no data collection are provided in the "Related Links" sidebar. (en)
