The Trimble Thunderbolt has a message (0x5A) that outputs raw receiver measurement data.  One value is "code phase" (along with PRN, sample length, sig level, dopple, and time-of-measurement).   This is a single precision floating point number in units of 1/16 of a chip.   Does anybody know how to massage this value into either a carrier phase (in cycles) or a pseudorange (in meters).    The reported code phase values tend to be in the 1000 ... 10000 range.
