serial zei:Heb ff zitten opzoeken en het klopt dat het amerikaanse leger toegang heeft tot veel preciezere gps maar ik heb nergens het verschil in nauwkeurigheid kunnen vinden...
de reden waarom gps voor de marines veel precieser is:
wikipedia.org zei:The satellites also broadcast two forms of clock information, the Coarse / Acquisition code, or C/A which is freely available to the public, and the restricted Precise code, or P-code, usually reserved for military applications. The C/A code is a 1,023 bit long pseudo-random code broadcast at 1.023 MHz, repeating every millisecond. Each satellite sends a distinct C/A code, which allows it to be uniquely identified. The P-code is a similar code broadcast at 10.23 MHz, but it repeats only once a week. In normal operation, the so-called "anti-spoofing mode", the P code is first encrypted into the Y-code, or P(Y), which can only be decrypted by units with a valid decryption key.
