SOHO Recovery Updates |
7 September 1998
Battery recharging continues. Propulsion subsystem temperatures
are being maintained.
Two alternative solutions which use fewer thrusters for attitude
recovery are being studied:
Solution A consists of:
- Thruster test
- Despin of S/C to low rate around Z-axis
- Triggering of ESR without gyro roll control
Solution B consists of:
- Thruster test
- Despin of S/C to low rate around Z-axis
- Spin-up around X-axis while X-axis stays oriented towards Sun
- Stabilization of attitude by spinning up reaction wheels
