Envisat Manoeuvre and Mass History

The Manoeuvre History file provides information on all calibrated Envisat manoeuvres.

The very first record in this file indicates when the file was updated (41 is our satellite id for Envisat). The following paired records contain the manoeuvre information. The first record of a manoeuvre (indicated by a 1 at the end of the record) contains the start time (UTC) of the manoeuvre, followed by the manoeuvre acceleration components (km/s^2) in the radial, along and cross-track direction. The next record of the manoeuvre (indicated by a 0 at the end of the record) contains the end time (UTC) of the manoeuvre, followed by the same manoeuvre acceleration components. The delta-V (m/s) for any direction is computed by taking the time difference (s) between start and end time of the manoeuvre and multiplying this by 1000 x the acceleration for that direction.

The Mass History file provides information on all Envisat mass changes.
