"Interestingly, the only thing stopping civilians from using the P code is the knowledge of the value of its chipping sequence. If the formula to generate the P code was publicly known, there’d be nothing stopping civilian GPS receivers from locking on to it, with the exact same techniques as are used for the C/A code."

I didn't finish reading the whole thing but was curious. Is there any way of brute forcing it or some other trick to get the chipping sequence to get the P code for more precise GPS?
