X-SAT Micro-satellite

NTU satellite marks three years in space
Published on: 19-April-2014

Singapore’s first locally-built satellite has travelled nearly 700 million kilometres, taken 8,000 photographs and completed 4,400 successful telecommands while orbiting Earth.

All this was achieved while surviving several solar storms, hazardous radiation and more than 30 near-collisions with space debris.

The X-SAT satellite will mark three years in space this Sunday, 20 April. The 105kg micro-satellite, developed by Nanyang Technological University (NTU) and DSO National Laboratories, was launched into space on 20 April 2011 on a three-year mission. It has performed beyond expectations to survive the harshness of space and is still fully operational.

Singapore’s most well-travelled two-year-old has gone to space and seen Madrid, Venice, Paris and Dubai. The traveller has also survived solar storms, radiation and 15 near-collisions with large chunks of space debris. Today, the Republic's first locally-built satellite, the X-Sat, celebrates its second anniversary in space. Built by NTU and DSO National Laboratories, the X-Sat has taken almost 5,000 photographs of Earth, helping researchers to monitor sea pollution, forest fires and other environmental changes.

First locally developed satellite invaluable in helping to monitor environmental change

One year in space, and Singapore's first locally designed and built satellite has not only captured images of Sumatra's forest fires and the Bangkok floods, but also had a few near misses with floating debris.

Since last May, X-SAT, which hovers 800km above ground, has taken and beamed back more than 1,000 satellite images from space to help researchers on the ground monitor the effects of environmental changes.

Associate Professor Low Kay Soon, one of X-SAT's team leaders, said the National Environment Agency and environmental consultancy Sentinel Asia have benefited from X-SAT's images.

The red-and-black photographs - with red denoting vegetation and black representing bodies of water - can be used to measure soil erosion, sea pollution and environmental changes within an area of 50km by 30km.

Making History – X-SAT First Anniversary

On 20 April 2011, another first was made in Singapore’s history as the nation’s first indigenously built micro-satellite, X-SAT, was successfully launched into the space on board India’s Polar Satellite Launch Vehicle PSLV-C16 at 12.42pm, Singapore time from the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh, India.

Designed for earth monitoring missions, the X-SAT is the result of a close collaboration between DSO and NTU, as engineering experts from both institutes came together to realize a vision.

Today marks the first anniversary of successful operation of X-SAT. X-SAT has completed more than 200 imaging missions, capturing over 1200 images across all continents. Many of these images have been sent to the National Environment Agency (NEA) and Sentinel Asia, a Pan-Asia satellite-based disaster monitoring effort for further assessment.

The success of this satellite has resulted in a joint venture comprising of NTU, DSO and ST Electronics to market the manufacturing and services for small satellite business. NTU students are also working towards the development of pico- and nano-satellites named VELOX-P and VELOX-I. These student’s built satellites are scheduled to be launched by 2013.

NTU’s satellite wins Defence Technology Prize by Mindef
Published on : 31-Oct-2011

The team from NTU and DSO National Laboratories, who successfully designed, built and launched Singapore's first-ever microsatellite, known as the X-SAT, was one of the winners of the Defence Technology Prize – the Ministry of Defence’s annual award to honour the finest in defence research and engineering. Five teams and one individual received the awards this year. The 120kg X-SAT monitors environmental changes, such as forest fires and oil pollution. Launched on April 20, it will orbit the earth for three years, while capturing images within a 12m resolution.

 

X-SAT beams images back to Singapore
Published on : 25-May-2011

Singapore’s first locally-built micro-satellite has started transmitting images back home. NTU embarked on the project with DSO National Laboratories in 2002, hoping to generate interest among the young in engineering R&D. The X-SAT, as it is known, sent the first image of Singapore on 7 May, more than two weeks after its launch. On 7 May, the micro-satellite orbited within a 3,000-km radius of Singapore – an ideal range to send back its first image of Tuas. That morning, the satellite passed by the western part of Singapore. Four days later, the ground centre received the first complete image of Singapore. Scientists can use the satellite photographs to track environmental changes, such as soil erosion and oil pollution. Director of NTU's Satellite Research Centre, Associate Professor Low Kay Soon, said the successful transmission of images was a great achievement for Singapore. “Space science is the pinnacle of science and technology. We hope to train more undergraduates to work in the field of satellites.” X-SAT will be exhibited at the Science Centre Singapore over the June school holidays.

 

First S'pore-built satellite now in orbit
Published on : 21-Apr-2011

Singapore's first locally-built satellite has officially been launched into space. Riding on a rocket owned by the Indian Space Research Organisation (ISRO), the micro-satellite X-SAT blasted off from Satish Dhawan Space Centre in India on 20 April. The 105kg fridge-size satellite, which will be used to take photographs to measure soil erosion and environmental changes on Earth, was one of three riding on ISRO's Polar Satellite Launch Vehicle (PSLV-C16).

X-SAT is designed and built from scratch by scientists and engineers from NTU and Singapore's defence research body DSO National Laboratories. Now in orbit, X-SAT is establishing communication contact with ground control in NTU, a process likely to take up to a week. Once contact has been made, an initial health status of the satellite will be ascertained and confirmed. This includes checking its solar panels and communication systems and the IRIS camera, which can capture images of forest fires and sea pollution.

With the successful launch of X-SAT, Singapore is one of the first countries in Southeast Asia to have its own satellite in space. The launch capped more than nine years of hard work by scientists and engineers. NTU President Dr Su Guaning congratulated the team, and said the launch represents “a huge leap” in Singapore's efforts to build space technology. He added that he hopes X-SAT’s launch will “excite and inspire” more youth to take up engineering and venture into space technology.

 

S'pore's first satellite to launch today

Singapore will finally head to space on 20 April afternoon. The Republic's first locally-built micro-satellite will blast off on an Indian rocket at 12.42pm, Singapore time, from the Satish Dhawan Space Centre in India, barring last-minute hitches.

The 105kg refrigerator-size X-SAT will be one of three satellites riding on the Polar Satellite Launch Vehicle C16, which is owned by the Indian Space Research Organisation (Isro). The other two satellites are built by Russia and India.

NTU collaborated with the DSO National Laboratories to build and design the satellite from scratch. NTU and Isro scientists and engineers have been working closely in the run-up to the launch and stringent checks have been carried out. X-SAT will orbit for three years at a height of 800km and take photographs to measure soil erosion and environmental changes on earth. It will then relay data to a ground station at NTU. X-SAT's launch will make Singapore one of the first Southeast Asian countries to have a locally designed and built satellite in space.
