n1.taur.dk

n1 is a stratum 1 server steered by pair of GPS receivers.
n1 exists because I need a reliable source of time. One where I know it'll either give correct time, or be honest and say it is unsynchronized. I've been burned one time too many.

2018.6.1: Transceiver upgrade and antenna relocation
The transceiver driving PPS over the 133m long cat5e cable between the receiver (GPS1) and the server had died halfway and gotten weak. Since I had to unmount GPS1 anyway, it now lives in a new location. I may be better, but it might not. Time will tell.

2018.5.31: gpsd died. Again.
Now running on github.com/kkpdk/refclock-tools/ .. Eating my own dogfood, and it is yummy.

2018.5.21: new clock wiggling
After the update, the clock is now wiggling a few microseconds every two hours. It has no effect, but it is annoying not knowing what causes it. Something is causing bi-hourly temperature excursions.

2018.5.20: Downtime during upgrade
An update that was supposed to take half an hour ended up taking several and a road trip. There will be another round of updates, but for now, it is stable.




Sky view
This is an intensity-graded plot of signal strength, seen both as the usual sky view, and as a south-centered cylindrical projection. Blue indicates that the satellite is excluded from the solution, red that the receiver has lost lock.
