USB GPS gizmos generally don't have a PPS and the timing on the NMEA sentences is generally crappy. (I may be biased by a few bad examples.) Does anybody have a list of ones known to work well? There is at least one GPS-USB with PPS, the Navisys GR-601W/GR-701W/GR-801W, They were hard to get retail. Looks like idealez sells them Taiwan for $47 for the 701W (Ublox 7), $50 for the 801W (Ublox 8) (plus shipping). I haven't tried ordering through them. Gary and/or Mark may have some for sale. ---------- Plan B is a GPS breakout and a USB-serial breakout and a few wires. 4x less USB jitter if your USB-Serial chip is full-speed. I got mine from SparkFun: Venus GPS with SMA Connector https://www.sparkfun.com/products/11058 USB to Serial Breakout - FT232RL https://www.sparkfun.com/products/12731 ---------- Google found this. I don't know anything more: https://www.zti-communications.com/z050-gps-dongle/ -- These are my opinions. I hate spam.
