Yea satellite has that high latency, ive seen Sat pings above 1000 ms
there is no way to fix it, its the long distance packages has to travel
tracerts is very good to use to find overload problems or bad routing between your ISP and some servers.
if you see a big jump in ping eg from node 6 to 7, you can wonder why, maybe node 7 is 2000 miles away from node 6 and that will make a natural ping increasing, even on fiberoptic.If ping gets better in node 8 then 7, it might also be a deprior of ICMP traffic on that node.
ping to first hop is also very important, it has a big impact on speed and might give you loss.
cable and dsl should have a ping to first hop (gateway) between 5-15ms, unless it has a stabilitation filter for dsl users living far away from CO then it might be around 30 ms.
