USB 1.1 is good enough! You got a jitter or latency problem you can't solve with 12 Mbit/sec, rock-solid on a point-to-point link?

I'd like one of the GR-701W for testing. I notice navisys.com now has a GR-801W, with uBlox 8. 72 channels with GPS & QZSS (L1), GLONASS, BEIDOU, WAAS, EGNOS, and MSAS. But strangely, not RTCM 3.x support, and still USB 1.1: http://www.navisys.com.tw/products/gps_gnss_receivers.htm Unrelated to the NTPsec, but related to gpsd, eventually we'll need to support some high update rate GPS. The GR-801 can do 18Hz. RGDS GARY --------------------------------------------------------------------------- Gary E.
