Telco workloads and 5g require precise time using technologies like ptp. The cheaper, more commodity those solutions get the better.

- _3u10 5y agoIf only these devices had a clock capable of measuring time to within 1 nanosecond. If one has such an accurate clock they might be able to accurately plot their position on earth to within 1 ft merely by checking the timed pulses of orbiting satellites.
- jazzyjackson 5y agoI guess you're downvoted for being sarcastic or maybe people don't know 20 dollar GPS chips provide a ~10 nanosecond resolution clock
- SAI_Peregrinus 5y agoAnd GPS-disciplined oven controlled crystal oscillators (OCXOs) provide some of the best frequency accuracy and stability around. They range from about a hundred dollars up through a few thousand, depending on phase noise.
- _3u10 5y agoHaha I have no idea. But yeah just call the GPS algo a Time AI and voila, $21 m in funding to go get some kids in shenzen to put a GPS chip on a USB, PCIe, NVME slot. Hey look we got a GPU to learn the Kalman filter algo. Many are actually better than 10 ns basically a 1 foot CEP is 1 ns. If they are fixed and always on the accuracy it can build over a day is incredible.
- jazzyjackson 5y agogranted it does need an unobstructed view of the sky, so getting it on a PCI-e board would be an innovation (:
