    Satellites have some lag time. Not much, but some. Still makes most of them not that relevant for moving targets, best you can do is draw a 500km x 500km square on the map from where you saw the CVBG 1 day ago.

    I'm saying the picture was taken on the 18th September, which the article says as well, and is also present on the picture in two locations.

    Come on, what else could my 18th September have referred to...

    What are those strange things that were marked with red dots in the picture? Are they unicorns? Fancy seeing these mystical creatures there.

    I'm not sure if you're deliberately being facetious or not, but they're meant to signify 726 LCACs as shown obviously by the key in the bottom left corner.

    If there's something so obvious and blatant on a picture like strange dots it's usually a good idea to closely look at the picture to see if there's an associated explanation for it.

    Interesting. I wonder if US spy satellites are constantly watching most Chinese vessels, live tracking some of them in case something happens and they need to know where they are.

    Is it possible to shoot those spy satellites? Does the Chinese track ships of foreign enemies?

    @PeoplesPoster, only GEO sat can track in real time but with useless resolution as of today. MEO (like Keyhole at 250km) and below can track in near real time if there are enough number (a constellation) to increase the revisit frequency. So far no country has deployed such system yet, but China is known to be deploying such system with a time gap small enough to be regarded as real time. This system has been discussed in this forum.

    @Pika, maybe not constantly, there is no such capability by anybody yet. Live tracking of some important target for 20 minutes when they ALREADY know where the target is WITHIN a boxy area? I think US is already doing that for decades by Keyhole.

    @Peter2018, one does not need to physically shoot the spy sat. Just use laser to dazzle the optical sensor or focused radar beam to jam the sat would do the job. US has complained about China laser dazzling their sat some years ago.

    Yes and yes.

    But shooting down another country’s satellite would be seen as a hostile act, at the very least the US would retaliate by shooting down Chinese satellites. “Freedom of Space” as it’s known has been tacitly recognised since the first spysats went up in the early 1960’s. While they mean that another country can see what you’re up to, you can also keep a close watch on them and make a Pearl Harbour style sneak attack impossible. So the major powers are content to put up with the nuisance because overall it helps to reduce tensions.
