What is the problem you are trying to solve?  Satellite links have a
fairly constant round-trip delay and the RTT calculations built into
TCP will happily compensate for this.  As long as the TCP window size
is larger than the delay*bandwidth and the packet loss probability is
well below 1 packet per window, TCP should work fine.

How does the transmitter confirm that the receiver has received packets
and can therefore drop them from its transmit buffer (or resend them if
they are not received)?  In particular, if there is no traffic for a
period, the only way that the last packet (before the break) can be
confirmed is via acknowledge timeouts.
