Understanding Antennas based on GPS

  1. Feb 11, 2012 #1

    I know that a GPS receiver module receives a number of signals coming from GPS satellites and the receiver can distinguish between them based on a number 1-32. Is there a limit to the number of signal one can send on a specific carrier frequency? Is there a limit to the number of signals a receiver can decode at any point in time and if yes what is the component that is responsible for this number?

    Note: I hope I posted in the right forum :D

    Hi there,
    welcome to the forums :)

    there 's lots of good info on the www about GPS signal decoding,
    here's just one of the many GOOGLE returned

    There are many ways to encode signals, regardless of if they are from a GPS satellite or multiple telephone signals through a optical fibre or microwave link etc
    to name a few....
    TDM = Time Division Multiplexing
    FDM = Frequency Division Multiplexing
    CDMA = Code Division Multiple Access

    Some google searching on digital signal multiplexing systems is likely to bring up lots more examples :)
