Thermal monitoring is important for the camera, therefore thermal measurement has to be accurate because changes in temperature can cause data error. Besides thermal, power requirements are one of the most important parameters in satellite development. This paper aims to conduct thermal and power testing from a data logger. The data logger which is an instrument to read data from time to time. From the test data, it can be seen that the ADC, PCB and Charge Coupled Device temperature at each Image Interface Modules will increase drastically when the camera is on the operation mode. The temperature at each Image Interface Modules increases for about 11.41° C, 13.61° C, 8.21° C and 7.81° C for ADC, PCB, Charge-Coupled Device channel 0 and Charge Coupled Device channel 1 respectively. Barrel temperature does not change significantly when the camera is turned on. Barrel temperature at each Image Interface Modules changes in the range 23C − 24C according to ambient temperature. For power consumption based on line period testing with line period mode using an altitude range of 485 km − 700 km. The initial power needed at an altitude of 485 km is 18.77 W.

LAPAN-A3 satellite data has been studied for earth observation and can be utilized for monitoring paddy fields, built-up areas, forests, rivers, fishponds, shrubs, sea, agricultural lands, and bare soils. But, as a sun-synchronous satellite, LAPAN-A3 has demerit of little revisit time for one specific area. Therefore, off-nadir imaging becomes one essential trait of the satellite to increase target monitoring from 17 times to 71 times in a year. This paper aims to organize the development process of off-nadir strategy in acquiring target image in Indonesia. With two kinds of off-nadir maneuver, inertial pointing maneuver and wheel speed maneuver, LAPAN-A3 satellite can conduct off-nadir imaging up to 34.5° roll angle maneuver. Furthermore, wheel speed maneuver with roll angle and roll rate approach presents the improvement in time efficiency of the maneuver, from 1 hour and 35 minutes executing time in inertial pointing to 25 minutes in wheel speed maneuver, making it become promising candidate for time-constraint off-nadir imaging.","PeriodicalId":376964,"journal":{"name":"2019 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128326964","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}

There are several types of optical filters: bandpass filter, long-pass filter, and short-pass filter. The next microsatellite developed by Satellite Technology Center is LAPAN-A4 Satellite. This satellite brings Medium Resolution Multispectral Imager (MRI) using SLIM4 and also Experiment LAPAN Line Imager Space Application (ELLISA). Moreover, this satellite also brings thermal imager which is called microbolometer, and experiment Short Wave Infrared (SWIR) camera. Especially for spectral band Long Wave Infrared (LWIR) cameras in LAPAN-A4 satellite will be narrowed down to $10.4mu mathrm{m}- 12.5mu mathrm{m}$, therefore a band filter is needed for blocking and passing these wavelengths. The method used to design the optical bandpass filter LWIR microbolometer camera is by determining the required spectral response. The response spectral required refers to the LANDSAT 8 Thermal Infrared Sensors (TIRS) bands 10 and 11 with spectral response $10.60 - 12.51mu mathrm{m}$, Centre Wavelength (CWL) of band 10 and 11 are $10.9mu mathrm{m}$ and $12.0 mu mathrm{m}$, and Full-Width Half-Maximum (FWHM) of both band are 0.6 $mu mathrm{m}$ and $1mu mathrm{m})$), and also determine the substrate filter material to be used. The design results show that, the LWIR bandpass filter has a spectral response of 10.4- $12.5mu mathrm{m}$, CWL $11.45mu mathrm{m}$, and FWHM $2.1mu mathrm{m}, max$ peak transmission is 80.21%, and capable of blocking at wavelengths of $7-10.4 mu mathrm{m}$ and $13-16.5 mu mathrm{m}$, the material used in this design uses Germanium (Ge) because it has a wavelength of $2-16 mu mathrm{m}$ which can work on spectral IR transmission.","PeriodicalId":376964,"journal":{"name":"2019 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124786894","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 paper aims to compare how LAPAN-A3 spectral quality changed with different acquisition modes. Three scenes of LAPAN-A3 with different acquisition modes ranging from nadir to extreme off-nadir mode were analyzed. Using Sentinel-2A Multispectral Instrument data as the reference, geometric co-registration was performed, and the Root Mean Square Error was kept at maximum (<2.5 pixels). Pseudo-invariant features were selected semi-automatically using threshold values based on the Normalized Difference Vegetation Index and Normalized Difference Water Index. The digital number produced then compared to Sentinel-2A data. Pearson correlation coefficient, as well as linear regression, was calculated for four corresponding bands. Generally, the results show a decreased correlation value between the corresponding datasets as the roll-angle increased. The correlation value went down from 0.623 (Off-Nadir) to 0.497 (Extreme off-nadir) on Near-infrared band.","PeriodicalId":376964,"journal":{"name":"2019 IEEE International Conference on Aerospace Electronics and Remote Sensing Technology (ICARES)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116035173","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}
