A calendar is available in order to compute the begin and end dates of Topex/Poseidon, Jason-1 and Envisat cycles.
This calendar is valid for:
- Topex/Poseidon on its initial repetitive orbit from 1992/09/14 (cycle 0) to 2002/04/24 (cycle 353)
- Jason-1 on its initial repetitive orbit from 2002/01/16 (cycle 1) to 2009/01/26 (cycle 259)
- Envisat on its initial repetitive orbit from 2002/04/09 (cycle 5) to 2010/10/18 (cycle 93) (Note: there are some data on the beginning of cycle 94 until 2010/10/22)
