The field of nanosatellites is constantly evolving and growing at a very fast speed. This creates a growing demand for more advanced and reliable EDAC systems that are capable of protecting all memory aspects of satellites. The Hamming code was identified as a suitable EDAC scheme for the prevention of single event effects on-board a nanosatellite in LEO. In this paper, three variations of Hamming codes are tested both in Matlab and VHDL. The most effective version was Hamming [16, 11, 4]2. This code guarantees single-error correction and double-error detection. All developed Hamming codes are suited for FPGA implementation, for which they are tested thoroughly using simulation software and optimized.

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.

“…This section presents a novel fault-tolerant model for the AES algorithm, which is immune to radiation induced SEUs occurring during encryption and can be used in hardware implementations on board small OE satellites [24]. The model is based on a self-repairing error detection and correction scheme, which is built in the AES algorithmic flow and utilizes the Hamming error correcting code [25].…”

This paper is concerned with the use of commercial security algorithms like the Advanced Encryption Standard (AES) in Earth observation small satellites. The demand to protect the sensitive and valuable data transmitted from satellites to ground has increased and hence the need to use encryption on board. AES, which is a very popular choice in terrestrial communications, is slowly emerging as the preferred option in the aerospace industry including satellites. This paper first addresses the encryption of satellite imaging data using five AES modes -ECB, CBC, CFB, OFB and CTR. A detailed analysis of the effect of Single Even Upsets (SEUs) on imaging data during on-board encryption using different modes of AES is carried out. The impact of faults in the data occurring during transmission to ground due to noisy channels is also discussed and compared for all the five modes of AES.In order to avoid data corruption due to SEUs a novel fault-tolerant model of AES is presented, which is based on the Hamming error correction code. An FPGA implementation of the proposed model is carried out and measurements of the power and throughput overhead are presented.
