SATELIT RAZAK

RazakSAT is a Malaysian satellite carrying a high-resolution camera. It was launched into low Earth orbit by a Falcon 1 rocket on July 14, 2009. It was placed into an unusual near-equatorial orbit that presents many imaging opportunities for the equatorial region.

This satellite is Malaysia's second remote sensing satellite after TiungSAT-1, which was launched in September 26, 2000 on a Ukrainian Dnepr rocket from Baikonur, Kazakhstan.

Originally called MACSAT, RazakSAT's payload is mainly electro-optical, carrying a Medium-sized Aperture Camera (MAC) which is a pushbroom camera with five linear detectors (one panchromatic, four multi-spectral) weighing approximately 50 kg. The entire satellite weighs at about 180 kg.

The then-Prime Minister of Malaysia, Mahathir Mohamad renamed the satellite to RazakSAT in tribute to the second Prime Minister of Malaysia, Abdul Razak or known as the "Bapa Pembangunan Malaysia" (Father of Malaysian Development) for his contribution to Malaysia's development. This was held officially during Mahathir's working visit to Astronautic Technology (M) Sdn. Bhd. (ATSB) in 2003 at its premise in Technology Park Malaysia (TPM) in Bukit Jalil, Kuala Lumpur. It has since moved to its new premises at Hicom-Glenmarie Industrial Park, Shah Alam, Selangor. ATSB is a wholly-owned company of the Minister of Finance Inc.(MOF) and reports to the Ministry of Science, Technology and Innovation (MOSTI), Malaysia

Banting, Selangor and ATSB's ground station in Shah Alam, Selangor consisting of a Mission Control Station (MCS) and Image Receiving and Processing Station (IRPS). Two other Malaysian ground stations would be able to communicate with the satellite as well; the Remote Sensing Malaysia groundstation in Temerloh, Pahang and the Malaysian National Space Agency groundstation in Sg.Lang Banting, Selangor. The IRPS will receive and archive images for post processing and distribution to the users.

RazakSAT is unique as it will be the first^{[citation needed]} microsatellite of its class to be placed at Near equatorial orbit (NEqO); unlike many other satellites of its kind that are placed on Sun-Synchronous Orbit (SSO). RazakSAT's orbital inclination will coincide with the latitude of its launch at Kwajalein, and that of the northernmost extent of Malaysia. Thus its launch will be nearly due east and quite efficient.

Satellite bus

The satellite bus used for RazakSat was jointly developed by ATSB and Satrec Initiative, a commercial satellite manufacturer in Korea. Satrec Initiative markets the bus system as the "SI-200
