However, since we are all nuts here, adding a GPSDO coulnt' hurt. 
(Usually you shoot outside, so access to the sky should be easy!) Then 
you'd also know position, which could be useful in accounting for 
numerous other thing like coriolis acceleration, gravity due to 
elevation, and gravity anomalies....  You could then calculate 
corrections for trajectories...
hmmm...
