The research grant was essentially for the development of datal communication terminals for LEO satellite systems. The services provided by LEO satellite systems are a variety. In this R&D work we have paid attention to services related to data acquisition from the ground or/and from the 0ceans.A particular service that we have focused relates to the oceanographic data collection. This data acquisition will support the characterization of the maritime environment in terms of salinity, temperature at various depths across the oceans in the world. Currently this service is referreed to as Array for Real-time Geostrophic Oceanography (ARGO). This ARGO system is supported by a number of international maritime organizations and countries. There are limitations on the present service and the R&D work initiated here is in collaboration with Institute of Telecommunication Research (ITR) Australia to extend the capability of the present ARGO system. This report essentially contains the design description and considerations for various hardware developed by ITR.
