RazakSAT® is a small Low Earth Observation (LEO) satellite orbiting the earth in uniquely Near Equatorial Orbit (NEqO) at nominal altitude of 685 km and 9 degrees inclination. It carries the Medium-sized Aperture Camera (MAC) which is an electro-optical payload of a pushbroom camera type with 5 linear detectors (1 panchromatic, 4 multi-spectral).RazakSAT® operated through its ground segment in Malaysia, consists of a Mission Control Station (MCS) and an Image Receiving and Processing Station (IRPS). A team of satellite engineers operated the MCS and executing the RazakSAT® mission plan, command generation and telemetry receiving, archiving and analysis accordingly. The IRPS will receive and archive images for post processing and distribution to the users.
RazakSAT® satellite has a Panchromatic band (510 - 730 nm) and 4 Multispectral Bands: Band 1: Blue (450 - 520 nm); Band 2: Green (520 - 600 nm); Band 3: Red (630 - 690 nm) and Band 4: Near-Infrared (760 - 890 nm). The spatial resolution of 2.5 m and 5 m for Panchromatic and Multispectral, respectively, covers a swath width of 20 km at the 685 km nominal altitude. Data is being quantized into 8 bits of 256 brightness values to represent information. With the high spatial resolution of 2.5 m, RazakSAT® allows a maximum scale of 1:25000 for mapping product. The following table summarizes MAC data characteristics.
