SPAS-01 Training:
1) SES S/W has not been updated or checked against FLT S/W
for ~1 yr -> item #'s are different, some functions
are different. Need to understand these differences
(Mosel & Hieb will look at this), & update where possible
2) SMS Training - no modeling of loss of lock between SPAS &
payload interrogator... No modelling of failures
3) SES - Check SPAS model (drift in gyros, etc....) model
hasn't been checked/updated
Note: Gyro comp (Bias for drift) requires 2 readings
of orbiter/SPAS angles (separated by ~30 min), &
transformation to calculate drift
-> Transformation/calculation will be done by HP41C
program
