SI-200 Bus

The SI-200 satellite bus was a model of satellite, based on the Malaysian RazakSAT, produced by the South Korean Satrec Initiative. The bus was suitable for small satellites where the accommodation of Earth observation or other scientific payloads is required, and was used on the Emirati remote sensing satellite DubaiSat-1 launched in 2009.

A satellite bus or spacecraft bus is a general model on which multiple-production satellite spacecraft are often based. The bus is the infrastructure of the spacecraft, usually providing locations for the payload.

Malaysia Federal constitutional monarchy in Southeast Asia

Malaysia is a country in Southeast Asia. The federal constitutional monarchy consists of 13 states and three federal territories, separated by the South China Sea into two similarly sized regions, Peninsular Malaysia and East Malaysia. Peninsular Malaysia shares a land and maritime border with Thailand in the north and maritime borders with Singapore in the south, Vietnam in the northeast, and Indonesia in the west. East Malaysia shares land and maritime borders with Brunei and Indonesia and a maritime border with the Philippines and Vietnam. Kuala Lumpur is the national capital and largest city while Putrajaya is the seat of federal government. With a population of over 30 million, Malaysia is the world's 44th most populous country. The southernmost point of continental Eurasia, Tanjung Piai, is in Malaysia. In the tropics, Malaysia is one of 17 megadiverse countries, with large numbers of endemic species.

RazakSAT Malaysian satellite

RazakSAT is a Malaysian Earth observation satellite carrying a high-resolution camera. It was launched into low Earth orbit on 14 July 2009. It was placed into a near-equatorial orbit that presents many imaging opportunities for the equatorial region. It weighs over three times a much as TiungSAT-1 and carries a high resolution Earth observation camera. Developed in conjunction with Satrec Initiative, the satellite's low inclination orbit brought it over Malaysia a dozen or more times per day. This was intended to provide greatly increased coverage of Malaysia, compared to most other Earth observation satellites. An audit report released in October 2011 revealed that the satellite had failed after only 1 year of operation.

CubeSat type of miniaturized satellite

A CubeSat is a type of miniaturized satellite for space research that is made up of multiples of 10 cm × 10 cm × 10 cm cubic units. CubeSats have a mass of no more than 1.33 kilograms (2.9 lb) per unit, and often use commercial off-the-shelf (COTS) components for their electronics and structure. CubeSats are commonly put in orbit by deployers on the International Space Station, or launched as secondary payloads on a launch vehicle. Over 1000 CubeSats have been launched as of January 2019. Over 900 have been successfully deployed in orbit and over 80 have been destroyed in launch failures.
