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

Hi It’s not real clear what the second chip on the board does. If it is just a bit to Ethernet converter then you are dealing with 2 bit data out of each of the four channels. You aren’t just doing tracking in that case ….4 channels at 2 bits -> 8 bits per clock. Clock at 38 to 100 MHz. That

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

This board just seems to be the RF front end for a GNSS receiver. You then have to do the whole business of acquiring and tracking the code, and then do the PVT solution, at which point you can make your own 1 PPS. Cheers Michael On Sunday, 14 August 2016, Gregory Maxwell
