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 designed in TUBITAK-BILTEN and prototyped in AMIS 0.35-mu m CMOS technology. The system uses an 8-bit bidirectional data bus, which operates at a maximum frequency of 40MHz supplying a throughput of 160 Mbit/sec and a SpaceWire interface, which provides a 100 Mbit/sec serial data communication link.

GEZGIN-2: An advanced image processing subsystem for earth-observing small satellites Ismailoglu, N; Benderli, O; Yesil, S; Sever, Ramazan; Okcan, B; Oktem, R (2005-06-11) 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...
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...
BILSAT-1 communication subsystem Belce, O; Telli, A; Maynard, K (2003-11-22) TUBITAK-BILTEN has initiated a project to develop and propagate small satellite technologies in Turkey. As part of this initiative, TUBITAK-BILTEN has worked with Surrey Satellite Technologies Limited (SSTL) to develop a 100 kg class enhanced microsatellite, BILSAT-1*. With the successful completion of this project, TUBITAK-BILTEN will be capable of producing its own satellites, covering all phases from design to production and in-orbit operation. The project was started in August 2001 and BILSAT-1, shown i...
Radar emitter emulation for research and experimental purposes. Çelebi, M. Bahadır; Koç, Seyit Sencer; Department of Electrical and Electronics Engineering (2009) The scope of this thesis is to implement radar emitter emulator in a low cost, portablehardware for operational and educational purposes. The model enables pulse train generation in real environment belonging to radar emitters for military exercises. The motivation comes from another research area which is to design effective algorithms for deinterleaving mixed pulse sequences in a suitable hardware and this thesis, covers the work done for implementing a hardware that generates mixed pulse sequences. First...
A mission analysis software for small satellites Koprücü, Salih Ulaş; Özçelik, Salih Abdullah; Altunay, Şulenur; Yağlıoğlu, Burak; Tekinalp, Ozan (null; 2019-09-18) In this paper, a mission analysis software is described for LEO small satellites which is developed by students participating in the APSCO (Asia-Pacific Space Cooperation Organization) Student Small Satellite (SSS) project. The software currently includes several functionalities such as orbit propagation with the options of SGP4 and numerical integration as well as calculation of groundtracks, eclipse durations, solar and albedo fluxes on the satellite panels, communication intervals, imaging opportunities ...
