GEZGIN-2 is a real-time image processing subsystem, currently being developed for RASAT, the second small satellite to be launched by TUBITAK-BILTEN, in 2007. It is an advanced version of the GEZGIN payload, implementing JPEG 2000 image compression algorithm and currently flying on the BILSAT-1 satellite. The main enhancements in GEZGIN-2 are the integration of the full processing path of JPEG 2000 algorithm in a single Field Programmable Gate Array (FPGA) for increased processing performance and high speed data links complying with the ESA Spacewire standard, for data transfer at a rate of 100 Mbps. In addition to JPEG2000, GEZGIN-2 facilitates image pre-processing for cloud/sea detection and image/data encryption implemented on a daughter-board called GOLGE. As in GEZGIN, GEZGIN-2 allows for adjustment of compression ratio for different mission times by means of run-time supplied parameters and full reconfigurability in orbit.

GEZGIN & GEZGIN-2: Adaptive real-time image processing subsystems for earth observing small satellites Ismailoglu, N.; Benderli, O.; Yesil, S.; Sever, Ramazan; Okcan, B.; Sengul, O.; Oktem, Rusen (2006-06-18) GEZGIN and GEZGIN-2 are real-time multispectral image processing subsystems developedfor BILSAT-1 and RASAT satellites respectively, the first two earth observing small satellites of Turkey. Main functionality of these subsystems is to compress in real-time multi-spectral images received concurrently from imagers, using JPEG2000 Image Compression algorithm. The compression features are controlled through user-supplied parameters uploaded in-orbit, so that the compression rate could be adapted to bandwidth, ...
GEZGIN: A case study of a real-time image processing subsystem for micro-satellites Ismailoglu, N; Benderli, O; Korkmaz, I; Yesil, S; Sever, Ramazan; Sunay, H; Kolcak, T; Tekmen, YC (2003-11-22) GEZGIN is a real-time image processing subsystem, developed as an R&D payload for BILSAT-1, the first earth observing micro-satellite of Turkey. The main functionality of GEZGIN is to compress in real-time multi-spectral images coming concurrently from the 4-band multi-spectral imager on BILSAT-1, using JPEG2000 Image Compression algorithm. The mission definition of BILSAT-1 imposes a 5.5 seconds interval constraint between two consecutive multi-spectral images with 20% overlap. GEZGIN fullfills this missio...
GOLGE: A case study of a secure data communication subsystem for micro-satellites Yesil, S; Sever, Ramazan; Okcan, B; Ismailoglu, N (2005-06-11) This paper presents a real-time data encryption/decryption subsystem developed for a satellite, which is planned to be launched in 2007 by TUBITAK-BILTEN. The subsystem GOLGE contains two ASICs, which perform encryption/decryption using AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman) algorithms and a communication interface unit. The data/command interface of the GOLGE module is implemented on a reconfigurable ASIC (FPGA), where the encryption/decryption processors have previously been de...
Differential Sensitivity Analysis for the Orthorectification of Small Satellite Images Bettemir, Oe. H. (2009-06-13) By using differential sensitivity analysis, horizontal and vertical accuracy of orthorectification of monoscopic images taken by small satellites without using Ground Control Points (GCP) is predicted. The analysis is performed by differentiating the colinearity equation of orthorectification procedure with respect to the satellite's interior and exterior parameters, and elevation obtained from digital elevation model (DEM). Square of the differential equations with respect to parameters are multiplied with...
Neutron background measurements with a hybrid neutron detector at the Kuo-Sheng Reactor Neutrino Laboratory Sonay, A.; et. al. (2018-08-02) We report in situ neutron background measurements at the Kuo-Sheng Reactor Neutrino Laboratory (KSNL) by a hybrid neutron detector (HND) with a data size of 33.8 days under shielding configurations identical to those used during the neutrino physics data taking. The HND consists of BC-501A liquid and BC-702 phosphor powder scintillation neutron detectors, which are sensitive to both fast and thermal neutrons, respectively. Neutron-induced events for the two channels are identified and differentiated by puls...
