NOTE 1 For instance before and after thermal cycles and other environmental exposures, between power cycles and according to time between runs. Unless otherwise specified, measurements are carried-out in the same environmental conditions (in particular, gyro channel environmental temperature being assumed identical within a specified temperature range).
NOTE 2 This term is defined in the present standard with a different meaning than in ECSS-E-ST-35 and ECSS-Q-ST-20. The term with the meaning defined herein is applicable only to the present standard.
