I have been looking at time synchronizing using arduino or raspberrypi. but well still I couldn't find something certain. does it possible with arduino? then how does it have something work? like motor or cctv

    $\begingroup$ CCTV, motors, GPS, and computers are widely different things; and it's unclear what is the relation between them in your question. $\endgroup$ – Antzi Nov 20 '18 at 7:09

    $\begingroup$ @J.Beom, This platform is for space exploration. For your arduino and raspberry related questions, please put the questions on raspberrypi.stackexchange.com or arduino.stackexchange.com . On these platforms you can get your related answer. $\endgroup$ – Amar Nov 20 '18 at 7:16
  • $\begingroup$ Short answer is definitely the GPS satellites in space. If your Raspberry Pi or Arduino have a GPS, they can access a very precise timescale while the GPS is connected. You can use programs to synchronize a stable real time clock while you have reception, and if you lose GPS that will be close. Most computers get time from an internet connection to time servers. Those are based on GPS receivers as well, but they have to use some tricks to account for delays over the internet. $\endgroup$ – uhoh Nov 20 '18 at 7:55

    $\begingroup$ Hi @J.Beom Welcome to Space! If you'd like to ask a question related to GPS and space, this is the right site, but first have a look at other GPS-related questions here to get an idea. The comment about the Raspberry Pi and Arduino Stack Exchange sites is good advice, but there also, have a look at the existing GPS questions before asking something that might be too broad or duplicate. $\endgroup$ – uhoh Nov 20 '18 at 7:59
