Ⅰ. Purpose

The purpose of this project is to develope a scientific satellite having about 100kg of mass, STSAT-2C, the third satellite loaded in KSLV-1. This satellite should be designed and integrated with very shorten processes to meet the schedule for launch of the KSLV-1. The STSAT-2C aims to verify the launching of the KSLV-1 into orbit and to prove the performance of the domestically developed space scientific payloads using an elliptical orbit. For these aims, the payloads of the STSAT-2C should be developed to tolerate over 1 year for observing the earth and the domestically developed space scientific payloads should be qualified according to the unique success criteria assigned for each payloads.

Ⅱ. Contents

1. Development of the STSAT-2C
The third satellite loaded in KSLV-1 and scientific satellite having about 100kg of mass, STSAT-2C, is developed with a simplified procedure comparing to other satellite development projects to meet the schedule for launch of the KSLV-1.
The goals of STSAT-2C are observing the orbit over 1 year and developing the satellite bus system for the missions. The satellite consist of bus systems for attitude and orbit control, command & data handing, electrical power, communication, and structure & thermal control. To get the utmost of existing satellite bus system and the ground station is essential for effective bus system development for the STSAT-2C.

2. Payloads for the science missions
The STSAT-2C contains Laser Reflector Array(LRA) for an accurate orbit control, Langmuir Probe(LP) for observing the ionosphere, and sensors for estimating total ionized dose and single event effect as payloads. And it consists a femto-second laser oscillator, a reaction wheel, a CMOS sensor, and an sensor for detecting infrared ray as domestically developed space scientific payloads.
The payloads of the STSAT-2C should be developed to tolerate over 1 year for observing the earth and the domestically developed space scientific payloads should be qualified according to the unique success criteria assigned for each payloads.

3. Supports for launch service and verifying orbit injection
Satellite Technology Research Center(SaTReC) supports integration of the satellite in KSLV-1 and launch campaign. After the lunch of the KSLV-1, SaTReC traces the STSAT-2C satellite to verify the orbit injection in the incipient stage.

Ⅲ. Expected Contribution

Through this project, it is possible to verify the launching of the KSLV-1 into orbit. Successful domestically developed space scientific payloads can contribute to development of independent and advanced technologies in importation restricted space science field. And the participated students have a chance to acquire practical business skills through hands-on experience. The acquired data can be used as a reference for the payloads data application project and scientific missions for the further satellites. This project can also contribute to the discover of follow-up projects which is essential for the advanced space technology development like a domestic developed launcher.
