Feasibility study on thermal survivability of X-Band subsystem on RASAT microsatellite

Okan, A
After the launch and commissioning of the first Turkish remote sensing satellite BILSAT-1(center dot), TUBITAK BILTEN has initiated the RASAT microsatellite project. RASAT will be a remote sensing microsatellite at low Earth orbit (LEO), with a mass of around 100 kg and an orbital average power of 38W. RASAT is planned to he launched in 2007 and will be the first satellite to be designed and manufactured entirely in Turkey.


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...

Doruk, Resat Oezguer; Kocaoglan, Erol (2008-01-01)
Purpose - This paper aims to focus on the implementation of the integral back-stepping control on the model of BILSAT - 1 satellite of the Turkish Scientific and Technological Research Council (TUBITAK).
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...
Experimental and computational evaluation of transient behavior of a typical satellite monopropellant propulsion system
Çilli Tarçın, Ayşegül; Aksel, Mehmet Haluk; Ak, Mehmet Ali; Department of Mechanical Engineering (2014)
In this study, a typical satellite monopropellant propulsion system is numerically modeled by using a commercial software and analyses are conducted regarding the priming operation of satellite propulsion system. Analyses are performed for different tank pressures, downstream line pressures, distance between the tank and orifice, distance between the orifice and latch valve, distance between the latch valve and exit valve, orifice diameter and pipe diameters. Moreover, a test setup is constructed and tests ...
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...
