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 in Fig 1, was successfully launched from Plesetsk Cosmodrome, Russia in 27 September 2003. In this paper the communication subsystem of BILSAT-1 is presented. The primary uplink is the S-band receivers and the primary downlink is the S-band transmitters on-board BILSAT-1, whereas VHF and UHF systems are also present as back-up for uplink and downlink respectively, UHF/VHF system is currently being used for commissioning phase due to omni directional coverage requirements. S-band being the nominal operation system has relative directionality. The data rate of uplink is 9.6 kbps for both S-band and VHF. However, S-band is capable of 2 Mbps and UHF has 9.6 kbps, 38.4 kbps and 76.8 kbps opportunities for downlink.

BILSAT-1: A low-cost, agile, earth observation microsatellite for Turkey Bradford, A; Gomes, LM; Sweeting, M; Yuksel, G; Ozkaptan, C; Orlu, U (2003-08-01) TUBITAK-BILTEN has initiated a project to develop and propagate small satellite technologies in Turkey. As part of this initiative, TUBITAK-BILTEN is working with SSTL to develop a 100kg 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. It is hoped that acquisition of these technologies will stimulate Turkish industry into greater involv...
Numerical and experimental investigation of the thermal behavior of a newly developed attitude Determination Control Unit in a Vacuum environment ÖMÜR, Cem; UYGUR, A Bilge; IŞIK, H Gürgüç; Tarı, İlker (2011-06-11) Within the framework of satellite programs carried out in Turkish Aerospace Industries, Inc. (TAI), a new Attitude Determination Control Unit (ADCU) has been developed. The present study involves the Thermal Vacuum Cycling Tests (TVCT) performed on the ADCU and the thermal mathematical model developed in order to assess the thermal behavior of the equipment under vacuum environment. For the qualification of the ADCU, 8 cycles of TVCT has been performed in a Thermal Vacuum Chamber (TVC). By demonstrating tha...
Turkish Small Satellite Program: Goals and policies Askar, M; Tekinalp, Ozan (2000-01-01) Information Technologies and Electronics Research Institute (BILTEN) has initiated a low-earth orbit small satellite project in Turkey. This project is part of a program to achieve expertise on satellite related technologies. The main goal of the project is to transfer technology on building small satellites. For the realization of the project an international contractor will be named. The contractor will be responsible of a technology transfer program as well as manufacture and launch of a small satellite ...
First LEO Satellite Built in Turkey: RASAT YÜKSEL, GÖKHAN; OKAN, ALTUĞ; Leloğlu, Uğur Murat (2007-06-16) BiLSAT* project was the first step to initiate and to improve satellite technologies in Turkey and it covered all major steps to establish the necessary infrastructure in Turkey to design, build and test a LEO satellite entirely in the country. As a second step, RASAT project has been initiated in year 2004. Except for some systems; like imaging system and solar panels, the technology of which are not yet available in Turkey; RASAT Will totally be built and integrated at TUBITAK-UZAY facilities. The imaging...
BILSAT-1: Power system sizing and design Orlu, U; Yuksel, G; Gomes, L; Hall, K (2003-11-22) BILSAT-1(1) is a 129 kg enhanced microsatellite developed by SSTL with TUBITAK-BILTEN engineers as part of a technology transfer programme. The main objective of the mission is remote sensing. The multispectral imager of the satellite has a 26-metre ground sampling distance at 686 km altitude giving a swath width of 55 km and the panchromatic imager of the satellite with 12-metre ground sampling distance gives a 25 km swath width. The satellite has off-axis pointing capability, provided by the ADCS systems,...
