KA-SAT is the first of the second generation of high throughput satellite (HTS) systems. Constructed by Airbus, it was launched in 2010. It delivers over 90 Gbps capacity over 82 spots in Ka-band over Europe, North Africa and the Middle East. It represents a complete infrastructure with the ground segment complement so as to deliver a suite of services including Internet access, broadcasting and satellite news gathering. The KA-SAT HTS system includes an integrated ground and satellite infrastructure: the ground infrastructure comprises a network of ten gateways that are connected to the main European point of presences, to the Internet backbone, to the network operations centre and a centralised operational control centre by Skylogic in Turin. Skylogic interfaces with all the customers. Besides the operational KA-SAT, there are four other HTS systems launched or to be launched by Eutelsat: EUTELSAT 3B launched in April 2014, EUTELSAT 36C in 2015, EUTELSAT 65 West A in 2016 and EUTELSAT 172B in 2017. These systems represent a range of HTS systems for Eutelsat, which push the envelope of applications and provide the performance critical to operators.

“…Thus KA-SAT, ViaSat 1, and Echostar 17 (aka Jupiter) can be considered to be in the second generation. Next generation HTS's will push for an increase in the system capacity and an optimisation of the satellite and system resources in order to make available higher capacities to the consumer while providing a quality comparable to fiber-to-the-home [9,11,12].…”

KA-SAT has represented a new generation of high throughput satellites (HTS) with the largest number of spots delivering a capacity of 90 Gbit/s for a wide variety of services ranging from internet access in homes to satellite news gathering and domestic broadcasting. HTS systems require a critical approach in terms of communication system requirements and payload analysis. This paper presents the typical system architecture of such systems and provides an analytical approach to elements that are required for the estimation of forward and return capacity, the key factor in these systems. These elements include the effective isotropic radiated power (EIRP) and the gain over noise temperature (G/T) cumulative densities, the carrier-to-inference (C/I) estimations and the capacity assessment for the forward and return links.

“…In parallel to the 5G evolution, the ever growing demand for high data throughput has triggered research efforts to improve the spectral efficiency of satellite communications. Very high or high throughput satellites (V/HTS) [3] are emerging satellite solutions that highly demand such spectral efficiency improvements. These systems deploy multiple beams that tessellate the coverage area in small beam footprints; thus, allowing frequency reuse across the coverage area.…”

Non-orthogonal transmission is a promising technology enabler to meet the requirements of the forthcoming 5G communication systems. Seminal papers demonstrated that non-orthogonal multiplexing techniques outperform orthogonal schemes in terms of capacity, latency and user fairness. Since it is envisioned that satellites will be an integral component of the 5G infrastructure, it is worth studying how satellite communication systems can benefit from the application of non-orthogonal transmission schemes as well. Contrary to common perception, communications through a satellite present a different architecture and face different impairments than those in the wireless terrestrial links. This highlights that a general overview is needed to gain insight into the satellite payload architecture. In particular, this works aims at describing different non-orthogonal schemes and payload architectures that are suitable for the satellite environment. In this regard, a novel taxonomy is presented based on different multibeam transmission schemes. Finally, guidelines that open new avenues for research in this topic are provided.
