Nutation Monitoring

The graph below shows the maximum daily nutation half-cone angle for the 2000-01 nutation period. Also plotted is the nutation forcing function in blue and the the expected nutation level without closed-loop Conscan control (based on 1990 data when Conscan was not used to control the nutation). This graph will be updated regularly during the nutation period.

For comparison, a similar graph for the 1994-95 nutation period is shown below.
