Dear Developers, Firstly, appreciate all for this amazing project. Gratitude!!! My application - Record some events/sensor readings in a moving vehicle 100MPH using a Ublox Neo-M8U GPS. Accuracy requ

Yo pisymbol! Uh, where is it? I don't have a 10Hz receiver. Just what I hear from everyone that tried: too much averaging, plus some delays. A tad old, and on the under-powered side, but prolly OK, i

Care to share the code?  Hard to debug something we can not see... Sure, no problem. It took years for gpsd to get the buffering right.  Many ways to fail... Yes, totally understandable. Which you

Yo Deven! People have pretty big inboxes these days. Depends, a lot, on the GPS. For u-blox, some prefer NMEA, some prefer binary, so gpsd treads lightly on the existing u-blox config. Pretty common
