I am doing some research into GNSS (Global Navigation Satellite Systems) and have come across various signals listed as having the in-phase or quadrature channels modulated with BPSK(2) or BPSK(10), etc. However, I am struggling to find a definition of BPSK that includes this additional parameter.

What does the (n) signify in BPSK(n)?

I understand the basic concept of BPSK - Binary Phase Shift Keying and have implemented this in very basic tests by multiplying the LO by 1 or -1 for a 1 or 0 chip respectively.

It has been suggested by a colleague that the n is simply the chip rate and that BPSK(1) is a chip rate of 1MHz, BPSK(2) 2MHz, BPSK(10) 10MHz, etc. as mentioned in the comments by Jim Clay.
