you probably wouldn't have to search for the carrier throughout the pacific anew every time. there would be a most recent know location and a radius where each carrier could be based on the time interval between searches.

for example with the gaofen 4 (assuming it has the 50m resolution and its coverage includes the western pacific), you could have one team responsible for keeping track of each carrier group in the coverage area at all times.

every once in a while you can get your LEO satellites to verify the suspected target and in between those verification just keep tracking the dots

"Could" is a conjecture. Please provide the technical analysis to support your assertion that it can provide coverage at all times.

Not actually. You have a habit of shifting conversations around and so I need to confine the conversation one at a time.

I should remind you that you are the one making the claim over China's near real time surveillance capability. To-date you have offer no evidence but conjectures to support your claim. I could easily just invoke Hutchens Razor and discount your assertion as merely unsubstantiated.
You are the one making the claim, so where are your technical analysis in support of your assertion?

The CBO study gives a baseline on satellite coverage as a reference point. It may be that a 1.0 m resolution is not required to classify a carrier. However it should be noted that texture analysis using algorithm is used to scan for the carrier. It is not an exercise of using the human eye to filter. Low resolution images is a source of error.

In any case as a rule of thumb measurement, the difference between a 1.0 m and 30 m resolution only increases the swath area by approx. 3 X. The Western Pacific is still a big ocean to search for a carrier.

As I said, show me your technical analysis in support of your assertion.

Just out of curiosity. Since the image quality is quite poor, could the ASBM accidentally lock-on to a near-by TI-class supertanker instead of the Gerald R. Ford class supercarrier :eek::eek::eek:

it's extremely difficult to find a carrier group in the middle of a huge ocean. Just think about how often a satellite would pass overhead.

Are you kidding?

Gaofen 4 with 50m resolution capability in geosynchronous orbit and continuous coverage.

Pick up the carriers when they are at port. Rescan every 10min as they can only move a couple of miles in that time. Task a LEO bird for a closer look if there are any doubts.

Did someone just mentioned the necessity of tracking a CVG over the whole pacific ocean? Why? PLAN is not going to attack a CVG near Continental America or anywhere except within the 2nd island chain. That is a much smaller area to cover with both satellite and OH long range radars, after initial detection long range UAVs can be used to monitor and track.

It would be easier to track the carrier from when it leaves port, otherwise re-acquiring it again in the open ocean may be an issue.

Gaofen 4 has an advertised viewbox of 7000km x 7000km, but has a visual horizon of one-third of the earth's surface, so it might as well scan the entire Pacific anyway

You should at least bother to find out for yourself the meaning of geosynchronous before commenting.

That is the maximal scan box. Captured frames is around 400 x 400 Kilometers in size.

I do know what geosynchronous orbit is.

Plus I imagine the satellite has some capability (thrusters) to re-orient and move its scan box. However, it would come at the expense of satellite life.
