What is the difference between the Sirf Binary and the OSP One Socket Protocol?

CSR (SirF) change the binary protocol whne they introduced the Sirf IV gps modules. The protocols are very similar but OSP has additional features.

Is you are using the ISM300x family of GPS modules use the Sirf Binary. If you are using the ISM4xx family then use OSP.
