Overview
The primary objective of this investigation is related to space geodesy and consists to better understand the role of the error propagation into the altimetric data analysis. It is expected to establish a kind of data base related to the errors in the various aspects of modeling, methods and data editing scheme. The technical aspects of the investigation will include: (i) analysis of the orbit quality and improvement of the precise orbit determination at local and global space scales thanks to an extended short-arc technique, (ii) analysis of the tracking measurements - laser and DORIS - including the monitoring of their associated error budget and the role of the error propagation into the orbit and the terrestrial reference frame, (iii) an absolute calibration campaign of the radar altimeter, and (iv) the determination of mean sea surfaces as well as the estimation of their temporal variations at different space scales, in particular at very low frequencies.The global analysis of error propagations which is proposed as a scientific objective must lead to better evaluate the limit under which the interpretation of the altimetric data should be corrupted.
