Sensor and guidance packages can now be designed to survive the shock of cannon
launch, so a grav or EM driver should be fine over the length of time of launch
impulse.

For ref.:
According to the Discovery channel show "Futureweapons", Episode "Smart
Weapons" (on last night :) ), the GPS guidance package on the new "Excalibur"
155mm artillery shell is designed to survive routine launch impulse of 8000g,
and in testing survived overpressure launch impulse of 16000g, while still
managing to arrive within 2 meters of a target at 20miles/32km range, even when
launched off-axis by 15 degrees.  Video clips on the Discovery channel website
(and maybe your TiVo).

Copperhead laser guided warheads and SADARM IR/radar sensors survived 155mm
cannon launch impulse based on 1980's and 1990's technology, respectively.
