[Sls-rfm] Fw: Ground Station Frequency Stability Cat. A- Action Item on Victor

[Enrico.Vassallo at esa.int]

But, yes, indeed, a requirement for stability over 10K seconds is needed. 
One use case is for a mission with a long round-trip light time (on the 
order of 10’s of minutes) and/or a long contact time, on the order of 
several hours. The stability is needed to maintain knowledge of the 
carrier  (& tones, if ranging via tones) frequency over those periods. 
 
The stability order would increase by an 1 to 1.5 OOM over that used for 
tau of 100 seconds.  There would also likely be a spec that the increase 
be linear or defined strictly by a polynomial, so it can readily and 
accurately be modeled.
