OAS insttype Detail for Poseidon-3 altimeter
|Definition:||Poseidon-3 is the main instrument on board the French-U.S. satellite Jason-2 launched in 2008 and was derived from the Poseidon-2 altimeter on Jason-1.
The Poseidon-3 altimeter is a compact, low-power, low-mass instrument offering a high degree of reliability. Poseidon-3 is a radar altimeter that emits pulses at two frequencies (13.6 and 5.3 GHz; the second frequency is used to determine the electron content in the atmosphere) and analyzes the return signal reflected by the surface. The signal round-trip time is estimated very precisely to calculate the range, after applying the necessary corrections.
Jason-2 data are being archived by the NODC as part of the Comprehensive Large Array-data Stewardship System (CLASS)
