On-board Payload Data Processing Systems
At the turn of this century, satellites which have demonstrated the feasibility of many space applications, enter in a new era. Today they have an additional mandate: they must provide a well-identified service to Users and/or to Customers. This is applicable not only to Telecommunication but also to Earth observation missions. Data products or derived information must be elaborated rapidly in ...
متن کاملUnified Multibeam Satellite System Model for Payload Performance Analysis
This paper presents a novel unified multibeam satellite system model for the performance analysis of different satellite payloads. The model allows the analysis in terms of Signal to Interference plus Noise Ratio (SINR) and CoChannel Interference (CCI). Specifically we formulate the SINR as a function of the multibeam geometry for a given user location granularity. Furthermore, we apply our mod...
متن کاملA Www - Based Distributed Satellite Data Processing System
Providing WWW access to remote sensing data requires to hold on-line not only the raw sensor data but also a variety of derived products. Pre-processing all these data introduces high costs for processing and archiving a static set of standard products. On-demand processing of data products is more flexible and requires less storage space but also makes it difficult to cope with high server loa...
متن کاملOngoing Developments of Future Payload Data Processing Platforms at ESA
Data compression is a key technology for many types of space missions. Compression algorithms can be implemented in hardware, software, or a combination of both. For software or combined hardware-software implementation the availability of powerful on-board processors is a key requirement. In the recent past, the data volumes produced by all types of space missions have increased significantly,...
متن کاملBand-monitoring Payload for a CubeSat Satellite
During changing sun activity, the ionosphere is responding accordingly and therefore it is interesting to observe the propagation behavior of shortwave bands. For the above mentioned purpose we have designed a bandmonitoring payload for an experimental CubeSat satellite. The payload consists of a receiver, which is able to receive SSB modulated narrowband signals in 28 MHz uplink band, and a tr...
