We used quicly as QUIC implementation and built our own little qperf (https://github.com/rbruenig/qperf) for running our experiments. We did not use a full-blown satellite simulator but rather focused on latency and capacity caps as well as (random) packet losses. We just used tc/netem qdisc for link emulation.
