I am looking for cheap GNSS board. Which must satisfy these requirements:
- Must output raw observations and ephemerides.
- Observations must include L1,L2 C/A Psuedorange and Carrier Phase.
- Must have external antenna connection.
- Output Protocol must be in Serial (RS-232 or TTL) or can be converted to Serial easily.
- Output Data Format must be well documented or well-known format.
Any suggestions?
@jitterboogie Couldn't see any external antenna connections. Beside that, RTK Facet is complete product. I am spesifically looking for board or component. But i found the board inside of it, (I think). it is overqualified.

Yeah, I?ÿ was just pointing you to the sparkfun site.?ÿ You can?ÿ build that unit with their parts or purchase it completed.
I guess you're seeking used old tech for your project?
What wheel are you trying to reinvent?

@jitterboogie I am not trying to reinvent the wheel or i am looking for used old tech ???? I wrote my own double differencing code which utilizes different approach on determining Delta Z component of the baseline. I am tring to test them on common receivers. So far, I tested on Topcon (Legacy-E and HiPER GGD) and South and results were better than their internal real time solutions. Buying whole kit or overqualified board is bit unnecessary for my research.
