[QUOTE="Hans Blaster, post: 77669422, member: 396028"] [Picard-Riker facepalm GIF] Have you just ignored everything we've said about how spacecraft are tracked and the delay time of communication, etc.? I don't know the actual interval between telemetry data from Voyager, but it isn't continuous. (The bit rate is extremely low and requires resources to receive the signal.) The properties of the spacecraft (position, distance, velocity) are accurately known at the points when they are specifically known. The model used to interpolate positions is, no doubt, a simplified version of the one that NASA uses to track the spacecraft. If you get the sky position, you'd have everything needed to point your 100-m radio dish at it and listen for yourself. Server! What nonsense! This is my biggest (and oldest) complaint about modern web design -- too much chatting with the servers, auto-page generation, etc. It sucks resources of local bandwidth, loads pages poorly under restricted bandwidth, and requires excessive server capacity to drive. This "server clock" notion of yours is just a tiny manifestation of this disease. Your computer (or mobile device) has an internal clock. It keeps good time. Most computers are configured to check with a time base server on regular intervals to prevent drift, etc. Cellular devices get the time updated when connecting to towers all the time. Your computer/device has a time (in UTC) that is just as accurate as any served from a remote NASA server. This complaint is bogus. That's not how motion works. Learn some physics. Go download the raw data if you like. I doubt you have the foggiest idea how to use it. [/QUOTE]
