The activity “Standards Preparation For SOTM Terminals“ is a study to define a common way to specify and verify Satellite On The Move Terminals (SOTM). Currently SOTM terminals are not consistently specified, nor independently verified for a number of key performance criteria. Under these circumstances, it is difficult for service providers, satellite operators, and end users to clearly understand the capabilities of the product being offered without embarking on expensive and lengthy trials. For the SOTM market to continue to grow, obstacles preventing fast and fluid transactions need to be removed, and a clear understanding of product performance needs to be developed. This activity will help move the SOTM market away from the characteristics of a niche market and towards a more established, consumer and manufacturer friendly one.
SPELL (Satellite Procedure Execution Language and Library, https://sourceforge.net/projects/spell-sat/) is a free, open source software package developed by SES in cooperation with GMV. The purpose of SPELL is to automate the execution of satellite procedures. SPELL works on multiple satellite platforms and can be interfaced to multiple ground control systems. Thanks to this versatility, SPELL increases the productivity of satellite controllers and engineers. The EASO project aimed to develop the satellite procedures and the automatic procedure converter software necessary to extend the use of SPELL to SES’ satellites fleet.
Next generation of flexible payloads will continue to widen towards the on-board processing (OBP) architecture as core of their design. The increasing of the satellite capabilities in term of service and applications demand is pushing the exigency to improve the current way to think and design a SATCOM payload.
At European level another mandatory exigency is motivated by the technological non-dependence and competitiveness as stated and stimulated by European Space Agency (ESA) and the European Commission (EC) in the frame of H2020. This is to guarantee not only the non-dependency from products coming from out-side Europe and its affiliate Countries, but also to improve the competitiveness and final product/solutions performances. First step to improve OBP technology towards a Next Generation (NG) is to implement new space components having rad hard characteristics and improved integration scale moving towards deep sub-micron microelectronics (DSM) technology at 65 nm end beyond.
The Study has given an outlook on the new space missions and related market interest that are stimulating the DSM as driver for the NG-OBP development. The description starts from an outlook on the state-of-the-art of the OBP technology, watching the main technologies up to now assessed. A view is provided on the relationships between the main actors can be involved in the space DSM and that contribute in the implementation and improvement of this technology.
The Study has been concluded providing a summary on the main key functional requirements derived by the provided technology assessment, useful for the future developments and contributing in convincing the satellite market to make the jump towards a new age of the satellite technology.
Another item provided in the concluding part of the Study has been the definition of a cost/benefit analysis providing a consistent technology roadmap.

Tactical and mobile satellite has become an increasingly important means of communications for European defence forces. Systems have predominantly been based around the UHF TacSat system, which is quick and easy to use, making it popular with users as a means of providing reliable voice and low rate data communications. However, the limited UHF spectrum and system capacity has meant that users have been looking increasingly to commercial mobile satellite systems to fill the gaps in capability.
The Next Generation Tactical and Mobile Satcom Systems Study aims to develop typical user scenarios; identify the capability gaps in current systems; and produce technical (and non-technical) solutions to address these gaps.
