Re: But.... Does it actually work?
Why would JPALS be running off Civilian GPS? The whole purpose of Military GPS with P-code and (Y) encryption is to reduce susceptibility to Jamming (it's not a complete solution but it helps). But even if it did run off civilian Differential GPS, so what, it can use any base station for correction as the Ship itself can transmit it's own DGPS reference signal as a station Baseline HD, which can correct for the local MSL variance on the Geodetic. Non-issue.
