Abstract

During satellite data transmission, several schemes of unavoidable errors may be experienced by the ground receiver. In the case of LAPAN-A2 imagery, those errors account for the presence of byte-missing effect disordering the position of pixel location on received raw data. Processing raw data contaminated by the byte-shifting effect will produce a line-drop pattern covering the original image on a particular line. This work is aimed to develop line-drop correction algorithm applied on three different levels of LAPAN-A2 microsatellite imagery data. A quantitative analysis was also performed on corrected images to determine the most suitable correction method for LAPAN-A2 imagery. In the end, a comparison between the developed method and an existing method has been demonstrated. It is confirmed that the developed method is better than the existing method in terms of producing a better quality of corrected images and performing a faster computational task. The developed method can be used as a solution to avoid data re-transmission to recover clear image data.

LAPAN-A2微卫星图像的线降误差校正

在卫星数据传输过程中，地面接收机可能会遇到一些不可避免的错误。在LAPAN-A2图像的情况下，这些错误解释了字节缺失效应的存在，使接收到的原始数据上的像素位置混乱。处理受字节移动效应污染的原始数据将产生覆盖在特定行的原始图像上的行下降模式。本工作旨在开发适用于三种不同水平的LAPAN-A2微卫星图像数据的线降校正算法。对校正后的图像进行定量分析，以确定最适合LAPAN-A2图像的校正方法。最后，将所提出的方法与现有方法进行了比较。实验结果表明，该方法在产生更好的校正图像质量和执行更快的计算任务方面优于现有方法。该方法可作为避免数据重传的一种解决方案，以恢复清晰的图像数据。
