For many years, CNES has been involved in orbit computation. At the beginning these calculations were made for experimental purposes. Then, they were improved for operational projects such as low earth orbiting satellites, geostationary satellites and interplanetary probes. More recently, CNES has decided to work (in collaboration with USA) on TOPEX-POSEIDON project which is realized for oceanic circulation determination. The use of a very accurate (5 cm) on-board altimeter requires a very accurate orbit estimation (some centimeters on altitude). Some aspects of modern technics of orbit determination are presented.
