However in several cases, star tracker sensor as the main attitude sensor, could not provide satellite attitude data as needed, which causes some significant performance degradation of the resulting image correction. This research aims to provide satellite attitude data needed for image correction based on multispectral image captured. The research characterizes the relationship between band coregistration distortion occurs on the image to satellite attitude while imaging. Measurements and data fitting which have been conducted show that satellite attitude while imaging has strong relationship to band coregistration distortion caused. However, the accuracy of satellite attitude calculated from band coregistration distortion has moderate accuracy, for about 3 degree for each satellite axis. Although the accuracy produced can be considered low for other applications, it is good enough to provide attitude data needed for image correction purpose.","PeriodicalId":113518,"journal":{"name":"2018 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121643448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has an altitude of 400 km and a velocity of 7 km/s. As an observation satellite, it is required to have high target pointing accuracy. However, being a low Earth orbit microsatellite, it experiences stronger external disturbances compared to larger and higher altitude satellites. Such disturbances are from the sun, and the Earth’s albedo and magnetic field. How these disturbances impact the pointing accuracy of the satellite must be determined to improve the setting of satellite missions, where such disturbances would be minimal. In addition, the satellite’s orbit decays quickly due to these disturbances, which means accurate satellite prediction is also critical in setting correct parameters for its targeting operations. In this paper, a comparison of different satellite prediction models to the Diwata-1 telemetry in varying TLE ages were done to determine which model fits best to the satellite’s orbit and what corrections are needed to minimize the difference between the actual satellite position from the predicted version, and in effect improve the satellite’s pointing accuracy. In addition, cases comparing the target area set during the creation, and the upload of the satellite command with the actual location captured by the satellite, were linked to disturbances from the sun and the earth to determine if these disturbances affect the target pointing of the satellite.","PeriodicalId":113518,"journal":{"name":"2018 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125075478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Airlines standard operating procedures used for detecting unstable approaches are different from one airline to the other so that occurrences in one airline cannot be used for benchmarking purpose on other airlines. An approach proposed in this paper is motivated by the fact that unstable approach is caused by the inability to manage aircraft’s energy required for conducting a stable approach. Therefore, quantifying the minimum energy required by stable approach is a necessary condition for detecting the approach type. A workable algorithm is developed and implemented on 2,000 flights landing at the same airport. Results show that unstable approaches detected by energy management are also included in the procedure-based results. This finding indicates that energy management-based unstable approach provides a generic approach for detecting unstable approaches which can be used for benchmarking purpose. In addition to that, the method proposed in this paper also requires fewer parameters in the analysis compared to the standard operating procedures which include many parameters to be analyzed for the same purpose.","PeriodicalId":113518,"journal":{"name":"2018 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129490117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to develop an autonomous image georeferencing for LAPAN-A3/IPB multispectral images so that entire image preprocessing can be executed autonomously. The algorithm is based on template image matching approach, by using numerous of previously processed images. The developed algorithm has been well validated and successfully georeferences LAPAN-A3/IPB multispectral images with a good accuracy. The time needed for the algorithm to process single image can be considered very fast, therefore the algorithm can be integrated into already established image preprocessing software. With this fully autonomous image preprocessing, each raw image captured could be processed inside one hour since its acquisition, allowing fast and consistent image distribution to the end user.","PeriodicalId":113518,"journal":{"name":"2018 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"211 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115275868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, Indonesia needs to master the ability of earth observation and natural resource exploration satellite based on remote sensing technology. Indonesia currently has mastered the micro class technology satellite system and also has an earth station infrastructure system that receives satellite data. The country considered the need to develop operational satellites nationwide to support the country’s self-reliance in the field of remote sensing satellite technology, and national technology development. Considering that the satellite industry is a complex system, it is necessary to apply an engineering analysis system that includes supply chain, business processes, and human resources (HR). This paper discusses the application of the Delphi method in prioritization of alternative key issues related to the Indonesia Remote Sensing Satellite Systems (InaRSSat) initiative. Delphi method is a method for structuring a group communication process so that the group can communicate effectively, allowing a group of individuals, as a whole, to deal with complex problems. This technique is one method of forecasting or estimating, which in this case is aimed at developing a consensus estimate of the future by asking an expert opinion on satellites and remote sensing applications in Indonesia. Stimulatingly, this study used an online method by utilizing website and WhatsApp application and executed in 3 (three) rounds. Results of the study are that key issues related to business process have more issues and ranked higher in the top 10 in comparison with key issues related to Supply Chain and Human Resources.

The objectives of this study were 1) Mapping out the concentration of chlorophyll-a, total phosphorus and transparency of Maninjau Lake through analysis of Landsat-8 OLI image and field survey, 2) Identifiying trophic status of Maninjau Lake using Carlson method through Landsat-8 OLI and surveys; and 3) Mapping the trophic status of Maninjau Lake using Landsat-8 OLI image analysis. Identification of trophic status are conducted using the TSI Carlson. The parameters used to determine the Carlson TSI are chlorophyll-a, total phosphorus, and Secchi Disk Transparency (SDT). The Carlson TSI parameter are modeled from Landsat 8 OLI image using stepwise regression. The variables that fulfill the prerequisite of stepwise regression is band 4 that strongly correlated with SDT data (R2 = 0.82). Band 5 and 6 ratios are also strongly correlated with a-chlorophyll data (R2 = 0.64). Band ratios of 3,4 and 5 are strongly correlated with total phosphorus data (R2 = 0.46). The TSI Carlson mapping results show that Maninjau Lake is in a light eutrophic to hypereutrophic position with the largest distribution being heavy eutrophic. The estimated error standard (SE) SDT was 0.2 m with 74,06% maximum accuracy, SE total phosphorus maintained 0.14 mg/ l with 76,69% maximum accuracy, and SE chlorophyll-a 0.02 mg/ l with 42% maximum accuracy.
