Line-Drop Error Correction for LAPAN-A2 Microsatellite Imagery

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.
