    Abstract
    A 3-Unit CubeSat, called TURKSAT-3USAT, is developed for voice commmunication in Low Earth Orbit (LEO). The spacecraft is planned to be launched by end of April 2013 from China with a LM2D launch vehicle. The 3USAT payload is a linear transponder operating in VHF/UHF. Most subsystems of the CubeSat have redundancy which is provided by COTS equipment and inhouse developed systems. The two payload are developed genuinly by project team. The payload power requirements results in excess temperatures exceeding 100oC. A remedy was developed to remove heat resulting from high power amplifier.  Other problems encoutered and resolved include grounding issues of electronic and RF systems, the transfer of data and power using PC104 form factor between 1U sections of for 3U COTS structures, thermal vacuum testing of payloads with supporting equipment outside of the chamber, cabling and "cold solder joint" among others. The 3USAT also includes many sensors and a camera for taking pictures.
    The full paper will disscuss in detail the encountered problems and methods developed to resolve them.
