Could you deliberate a bit?  I suspect that military receivers use L1 C/A,
L1 P(Y) and L2 P(Y). This is the exact same signals civilian geodetic
receivers has been using since about the Ashtech Z12 and its z-tracking.

It seems two out of three signals used by the military is affected by
interference close to L1 (1575MHz.)
