Trimble has a new "GPS smart antenna" - Acutime Gold. Whilst the Acutime 2000 has an RS-422 to RS-232 conversion box, the Acutime Gold comes with with an RS-422 to USB conversion box. It is supposed to achieve at least the same accuracy using the TSIP protocol (Palisade ntp driver) as the old Acutime 2000.
I thought USB inevitably gave poorer precision than RS-232. Apparently, I was wrong. How do they do it? Does anybody have experience with this unit? Does anybody have experience with it with ntp on Linux or FreeBSD? On windows, it uses a totally standard FTDI USB/serial driver, so it should work. But how well? (Yes, I know that we could also use the TTL PPS output and a level converter.)
