The fields of satellite-based services and applications are a growth sector, and continue to attract attention in line with technological development. This is giving rise to an increasing number of public and private satellitebased services, many combined with other information-based downstream products, some of which will form the 'essential services' that are seen to serve society in its second Millennium. This chapter takes as its starting point the loss of satellite-based connectivity for reasons of harmful interference, and discusses its consequences and impact on the parties involved in the satellite-based service chain. It examines whether the parameters for assessing the actual loss of satellite connectivity are suitably structured through the tools known to the law of contract, as well as the law of negligence (tort liability). It thereafter reflects whether alternative, state of the art solutions may be required at a future stage in response to the increasing availability of space-derivative applications, where digital commodities are delivered through combining various sources and types of satellite data-based information, integrated into the chosen combination of service or product required.
