[time-nuts] NUT4NT: Four-channel All-frequency GNSS RF-to-Bits

The NVS NV08C GPS receiver module is a rather nice little 32 channel GPS/GLONASS/SBAS receiver that has an output message that gives you the raw satellite bit streams.  They can be had for around $60 bare module  ($120 on a breakout board from sylphase.com).  They  also support carrier phase info, sawtooth correction output, and up to 10 Hz navigation rates.

Lady Heather now supports the NVS08C... it was a bit of a pain to do.   Several messages send values  (rather needlessly) in an 80-bit floating point number format that most compilers do not natively support.  Lady Heather converts those to standard 64-bit floating point values.  Their binary message protocol is basically Trimble TSIP at 115,200:8:ODD:1 (with optional support for 16-bit CRC's)
