Abstract: | This paper considers the potential to achieve improved throughput in time‐varying satellite links which have flexibility in information bit rate and/or transmit power. We assume that other parameters of the link budget such as antenna gains and operating frequency are fixed. Simple results are derived, which illustrate what improvements in data throughput or power consumption are possible under two low‐earth orbit scenarios: inter‐satellite links and satellite to ground communications.
