On average, there are eighteen to nineteen typhoons entering the Philippines’ area of responsibility in a year. It is also situated in the pacific ring of fire making it vulnerable to earthquakes and volcanic activities. Driven by these natural hazards, thePhilippines, under the Department of Science and Technology (DOST), funded the program, ”Development of Philippine EarthObservation Microsatellite (PHL-MICROSAT)”, which aims to launch the Philippines’ first Earth-observation microsatellite,PHL-MICROSAT-1, by 2016.
The microsatellite will be launched from the International Space Station with an expected altitude of 400 km and a near circular orbit similar to that of the ISS. It aims to provide robust and efficient near real-time status of the country’s environment
particularly for applications on disaster risk management, land-use and aquatic resource assessment and monitoring. On-board
the microsatellite are four science and engineering payloads: (1) High Precision Telescope (HPT) with a 3 m GSD and the capability to capture images in the visible and near infrared region which will be used in determining the extent of damages fromnatural hazards such as typhoons, earthquakes and volcanic eruptions; (2) Space Borne Multi-Spectral Imager (SMI) with Liquid
Tunable Filter (LCTF) which can capture images at 80 m GSD with a spectral range of 420-1050 nm. This payload will be usedin determining the health and composition of the Philippine oceans; (3) a panchromatic Wide Field Camera (WFC) with a field ofview of 180?x134? which will be used to capture images of cloud patterns and distribution as well as weather disturbances suchas tropical cyclones; and (4) a colored Middle Field Camera (MFC) with 185 m GSD which will assist in the microsatellite’s
attitude determination.

MicroDragon is the first 50 kg class microsatellite of Vietnam National Satellite Center (VNSC). It is being developed byVNSC researchers under instruction of the Japanese professors come from five universities including Hokkaido University, The
University of Tokyo, Keio University, Tohoku University and Kyushu Institute of Technology. Hokkaido University has been
responsible for the development of the science payloads based on the demands and requirements from the scientific point ofview.
Vietnam has a long coastal line with about 7% households in the fishery. Seafood plays an important role in developing
Vietnam economics. However, with increasing exploitation, natural aquatic resources are decreasing quickly. Development ofaquaculture is necessary for a sustainable economics. To do this, Vietnam needs an effective system which is an integrationof remote sensing and sea water sampling to monitor coastal water quality. Therefore, Mission of MicroDragon is ocean color
observation to provide data to researchers in fishery field and scientists in oceanography for assessing water quality and locating
living resources. We will use three imagers being composed of Space-borne multispectral Imager, Infra-Red Imager, and Triple
Polarization Imager onboard and Fluoro probes in the sea for the missions.

The remote sensing activities in Malaysia began in 1990s with concentration on the theoretical modeling of scatterers. Lateron, Malaysia started the sensor development and measurement which included the development of anechoic chambers as well as
ground based multifrequency and multiporalized scatterometer. In 2000s, the design and development of airborne remote sensing
sensor such as synthetic aperture radar (SAR) and optical sensor was initial. Plan to developed own airborne SAR and multisepctra camera as well as collaboration with overseas research institute was took place. In year 2012, sensors on board UAV (bothSAR and EO) have been successfully developed and tested, several high resolution images are obtained. In order to obtain larger
coverage of the illumination footprint, the spaceborne remote sensing is necessary. A spaceborne Hyperspectra imaging sensor
development project has been identified and initial by Centre of Remote Sensing and Surveillance Technologies, Multimedia
University and Astronautic Technology (M) Sdn.Bhd. In this project, a small nano-class satellite with onboard Liquid Crystal
Tunable Filter (LCTF) Hyperspectra Camera will be designed and constructed. LCTF hypersepectra camera will be designed tofit in the 10cm x 10 cm x 30cm nano-class satellite as well as confined to others electrical and mechanical constraint of spaceborne platform.The LCTF camera module consists of LCTF, Closed-circuit Television (CCTV) lens and Charge-couple device(CCD) board. LCTF sensor utilizes electronic controlled LCTF which allows rapid and vibrationless selection of wavelengthfrom visible to IR range spectrum. The major advantages of this LCTF sensors are light weight (approximate 250g for sensor),larger number of band selection (about 600 bands) and lower cost compare to conventional multispectral camera. Therefore, it
enables the usage of smaller space platform and further reduce the development cost and launching cost of satellite.Due to thelarge amount of data generated by the hyperspecta camera, it is necessary to reduce the size of the data so that the acquired data
can be downloaded to the earth station during every satellite pass. An onboard FPGA-based multispectral image compression
subsystem will be developed in this project to alleviate the memory and communication bottleneck of the small satellite.
