Two different pilot regions located in Turkey with different topographic characteristics were selected and analysis were conducted for these regions using ground control points obtained from 1:5000 scale aerial ortho-photos. Further analysis was conducted to analyze positional accuracy of resulting images using independent check points collected from aerial ortho-photos and Google Earth separately. The Advanced Spaceborne Thermal Emission and Reflectance Radiometer Global Digital Elevation Model (ASTER GDEM) was used for all different geometric correction processes for both regions. The accuracy of each geometric correction model was presented by root mean square error (RMSE) metric. Results showed that first and second order RPC refinement models together with Toutin Model provided highly accurate results for both regions with RMSE between 3–6 meters while rational function model with three and four RPC's provided comparatively lower horizontal accuracy. Applying the rational function model with the 20 RPC's, generated from ground control points using PCI Geomatica, reduced the RMSE comparatively to a better level but increased the number of ground control points required to perform geometric correction with this model. Moreover, results indicated a possible effect of terrain structure and land use /cover types on the accuracy of geometric correction.","PeriodicalId":434418,"journal":{"name":"2017 8th International Conference on Recent Advances in Space Technologies (RAST)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122490103","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}

The conventional sensor instrumental errors include bias and scale factor, temperature variations of the factors above and misalignment of sensitive axes. Also, additional quantities associated with the alignment error of the IMU to the turntable are to be estimated along with the parameters of sensor error model. Traditional methods of calibration usually involve different special set of operations for every parameter to be resolved. The main idea of the proposed approach is to avoid the requirement of any rigorous complicated sequence of operations in calibration experiment, and make the calibration procedure uniform, simple and non-strict to a feasible extent. The work is primarily focused on analysis of observability in the underlying estimation problem. The approach under consideration has previously proved its efficiency for traditional 6-axis inertial measurement units of different accuracy grades in real applications. The results of our study show that for a 3-axis gyro assembly all desired quantities, including conventional sensor error parameters, temperature variation coefficients and misalignment between turntable and sensor assembly, can be estimated simultaneously in one simple calibration experiment.","PeriodicalId":434418,"journal":{"name":"2017 8th International Conference on Recent Advances in Space Technologies (RAST)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114487078","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}
