[time-nuts] Improved CSRS-PPP service coming

[Mark Sims]

I just got an email from CSRS-PPP outlining their upgraded service coming 14 Aug 2018.

The new software supports all GNSS systems and will handle carrier phase observations for L1 only receivers.   Currently CSRS-PPP only supports GPS and GLONASS pseduorange data.   It will be interesting to see how the new software improves (or breaks) the antenna position results.
