Nanosatellites are persistently progressing and creating global communication and data transmission over the world. It builds up a colossal request for more progressed and dependable frameworks that are able to perform faster and reliable information transmission. An approach has been distinguished as a reasonable plot for the anticipation of single bit and multiple bit errors that are influencing On-board Nanosatellites. In this paper, we have proposed an Analytical Approach of Error Detection and Correction for On-board Nanosatellite. We have planned the framework with three distinctive parts as a encoding, error checking, and decoding portion separately. It has created in such a way that amid information exchange from satellite to ground station to analyze six camera pictures at the same time with the assistance of FPGA and EDAC strategies. To extend the proficiency, we have presented the progressed turbo mechanics EDAC for distinctive transfer speeds of satellite communication and execution examination with the AWGN and Rayleigh channel. EDAC strategies codes are tried in MATLAB and appeared in graphical plots. This method is straightforward and accomplishes unwavering quality and exactness, compared to other comparable strategies.

An FPGA-Based Solution for Computing a Local Stationarity Measure From Satellite Data

et al. 2022

View full text Add to dashboard Cite

The analysis of data variability from in-situ observations is essential for scientists and space mission controllers. Given the limited resources available on-board a spacecraft as well as the presence of the Field-Programmable Gate Arrays (FPGA) devices in modern spacecraft architectures, an efficient real-time monitoring solution should be deployed on these devices to use minimal computational and energy resources, and to reduce the main on-board computer utilization, thus making it available for other tasks. This paper describes the implementation of an algorithm for computing a local stationarity measure (LSM) on FPGA devices. The algorithm tests weak stationarity from the convergence of the partial means of the signal computed on subsets of increasing length, compared to the overall mean of the signal over a fixed-length running window; the window spans the entire signal. The algorithm is designed for an on-board implementation which monitors and detects changes of variables measured in-situ by scientific instruments (e.g., magnetometers). The design was tested with synthetic and real-time signals and provides results in very good agreement with a dedicated data analysis library specifically designed for the analysis of satellite data.INDEX TERMS FPGA-based design, High-Level Synthesis (HLS), local stationarity measure (LSM), magnetic field monitoring, satellites on-board processing, weak stationarity test
