heal.abstract In this paper, a proposal is sketched for realizing high data rate downlinks in next-generation Ka band low Earth orbit (LEO) Earth Observation (EO) systems. The work aims at realistically assessing the throughput advantage stemming from link adaptation strategies-embraced by most wireless and satellite communication standards-compared with non-adaptive transmission, which is the approach followed in conventional X band EO systems. The transmission strategies examined include constant, (static and dynamic) variable, and adaptive flavors of coding and modulation, each representing a different performance/system complexity trade-off. Practicality is pursued to the extent possible by incorporating state-of-the-art orbital, ground station, spacecraft, propagation, physical layer, and system implementation characteristics. The results manifest that under particular conditions, link adaptation offers throughput improvements of up to 100% against non-adaptive transmission schemes in Ka band LEO EO systems. © 2012 John Wiley & Sons, Ltd. en
