- samnardoni 8y agoErm, they aren’t going to change the nav data.
- elfchief 8y agoUntrue. There's a newer format for NAV data -- CNAV. It's currently broadcast on the L2 and L5 bands, and does indeed include a larger week number field -- 13 bits to be exact.
- samnardoni 8y agoWell, yes, that's true. But my point was that they aren't going to change the legacy nav data structure.
- tatersolid 8y agoWhy would a GPS satellite broadcast anything other than TAI in nanoseconds? I don’t know anything about GPS coding, but it would seem that anything calendar related like “weeks” is best left up to the receiver.
