While that's technically true, there are two caveats there:
- Corona satellites relied on a film dropped from the satellite and picked up on its way to the ground once pr twice per satellite, so it isn't very quick, and at the frontline a lot can be changed between drops
- Again, for some reason both Israeli and Egypt (including famous MiG-25RB flight twice a month) heavy relied on aerial reconnaissance, both high and low altitude, and for the mapping of the SAM sites too, and IAF suffered a lot of losses when trying to attack these sites without recent reconnaissance flights over them. So I cannot imagine that satellite data, if available, was enough.
