To solve the problem of dual-core communication error in SoC FPGA which caused by SEUs (Single Event Upset) for space applications, an approach of OCM (On-Chip Memory) reinforcement for mitigating SEUs is designed in this paper. Combined the Software EDAC (Software-Implemented Error Detection and Correction) technology using Hsiao code and the hardware resource of SGI (Software Generated Interrupt) in Zynq-7000, the design approach has the capability to correct the single-bit error and detect the double-bit error when CPUs access OCM. Furthermore, dual-core processors can write back to OCM synchronously when single bit error occurred. The verification result shows that the design approach has the advantages of low delay, high reliability and flexible design. Also, it can avoid the conflict of data write-back when the dual-core processors access OCM. The design approach makes full use of on-chip resources, it has no requirement of additional hardware resources to improve the capability of mitigating SEUs for dualcore communication in SoC FPGA.

Document-based collaborative design is a common method in the process of telecommunication satellite development. The technical parameters are distributed in a large number of documents, so the parameters are relatively isolated and there is no unified design platform. Therefore, this method has several deficiencies in the efficiency and traceability of collaborative design, and it is hard to realize the homology, reusability and version control of data. This paper presents a collaborative design method which is driven by structured parameters and can support a fast and efficient design iteration. Transform the parameters from unstructured to structured ones based on the XML technology. XML is used as the parameters carrier, and then establish the mapping relation of the parameters. A collaborative design platform is constructed, and based on the mapping relation of the parameters, the satellite development process is decomposed into tasks, and the design process is driven and iterated by the automatic mapping of parameters. Finally, we developed the collaborative design platform based on the 3D EXPERIENCE of Dassault Systems and ran an example of satellite project design, the result shows that the structured data-based method can effectively solve the problems of documents-based method, therefore it can enhance the efficiency and quality of satellite design.

Aiming at the difficulties of feature detection and feature matching caused by the geometric distortion and gray-scale radiation difference between dual-channel polarization images, this paper proposes an image registration method based on improved SURF with phase congruency and Log-Gabor filter. Firstly, the phase congruency model is introduced to eliminate the difference in grayscale or contrast between images. The SURF feature points are detected by edge images, which have more stable structural features. Then, the Log-Gabor filter is used to structure a robust local feature description. Finally, the proposed method uses the mutual information measure and RANSAC to perform feature point matching and refinement, and the multi-channel polarization images are accurately matched by the geometrical transformation and bilinear interpolation. The experiment results indicated that the proposed method can effectively improve the matching rate of feature point pairs compared with the classical SURF method. Especially for image registration with different polarization directions and different bands, the proposed method had more accuracy, which can reach within 1 pixel.

Non-gyro inertial measurement unit (NGIMU) uses only accelerometers replacing gyroscopes to compute the motion of a moving body. A new nine-accelerometer configuration of NGIMU is presented, with its experiment system built. In the system, the mounting error of the accelerometer installation, which seriously affects the precision of the navigation parameters estimation, cannot be avoidable. So a novel compensation algorithm for getting the correct accelerometer output is provided on the actual condition of existing the accelerometer mounting error. The algorithms uses the error function of the accelerometer output, and compensates the posture parameter in the traditional posture estimating algorithm to reduce the accelerometer mounting error. The simulation case and the experiment verification of the proposed methods for estimating the angular velocity are investigated based on the presented NGIMU configuration. The results show the feasibility of the configuration. In addition, in the angle measurement range of ±100 degree, the measurement precision can be improved for 3~4 degree.

Most of the traditional fusion algorithms are based on full sampling of the image. Compression sensing theory can use the sampling rate which is lower than the Nyquist sampling to sample the data, while achieving the integrity of the original data and accurate recovery. We introduced compression sensing in the framework of image fusion. After analyzing and comparing some fusion rules in image fusion, we proposed an improved fusion rule which combined the advantages of maximum method and linear weighted method based on the region variance. Simulation results on different type of images show that at the same sampling frequency, the proposed scheme is superior to the traditional mean algorithm in terms of peak signal to noise ratio, mean square error, correlation coefficient etc.

This paper reports an automatic mode-matching system for MEMS gyroscope based on actuation calibration technique. Two pilot tones (calibration signal) located on both sides of drive signal are applied to actuate the sense mode and estimate the frequency mismatch. Theoretical simulation and experiment result indicate the pilot tones should be located outside the frequency band between the sense mode and drive mode in order to fulfill mode match. Swept frequency experiment demonstrates the mode-matching system can achieve 0.56Hz mismatch frequency between the sense mode and drive mode.

The high-dimensionality, shifting and distortion are considered as the main difficulties in time series classification. In this paper, a novel technique based on dictionary learning and sparse representation is developed to conquer these difficulties. Dictionary, which is a set of series or segments, is able to reconstruct signals sparsely. We use dictionary learning to reconstruct time series and introduce k-nearest neighbor classifier based on dynamic time warping to improve the quality of approximation of dictionary. Sparse coding is used to reconstruct an unseen series. The class label of an unseen series is determined by the reconstructive error. Extensive experiments were conducted to test the effectiveness of the proposed algorithm. Experimental results show that the proposed technique achieved significant improvements compared with some existing algorithms.
