Hi, I discovered that to obtain efemeris valid for 2h, i have to record more than 1h of data.

Hi, I did my tests using pluto-sdr-sim project by Mictronics (based on gps-sdr-sim project). A Pluto SDR device is required, of course. Now Mictronics has a new project which have...

Thank you, It is possible but weird, because this delay is 1 microsec in gps-sdr-sim and 10 microsec in pluto-gps-sim. Of course, in both cases I used the same Pluto-SDR...

Hi, thanks for your response. I understand the 0.1sec increment. About "drift time" I did tests consist in measuring with an oscilloscope the time between two PPS signals, one from...

Hi, Now, I have replaced the factory xtal for an VTCXO (TYKACCSANF-40.000000). I mean measured time between a PPS from a receiver with real GPS signal vs a PPS from...

I´m realize that simulated GPS clock is not sync with other clocks. So, you say "The simulated GPS always gets a perfect 0.1s increment". Assuming host is able to do...

I have GPS based "time counters" devices, they move in open sky environments (were real GPS signal is available) and also in indoor environment with no (or weak) GPS signal....

About the drift, I discovered when xo_correction parameter is modified the speed of drift is affected, even drift speed can be stopped. Obviously it is not valid for drift control...

Thank you, The read frequency is about 0.0020 ppm

Hi. Anyone can explain how to feed the simulator from ublox receiver output? Can I get the message stream in hex format from receiver usb port? then, so how feed...
