ALSAT-1 [2] is the first Algerian satellite and it is part of a group of satellites collectively known as the Disaster Monitoring Constellation (DMC). [3] [4] The satellite was built by a group of engineers from Surrey Satellite Technology (SSTL) and Algerian Centre National des Techniques Spatiales (CNTS). It was the first DMC satellite to be launched of the five to seven that are planned. The DMC was the first satellite constellation designed for that objective. The launch took place on 28 November 2002 from the Plesetsk Cosmodrome in northern Russia on a Kosmos-3M launcher in -20 degree Celsius weather. It completed its mission after seven years and nine months in August 2010. The satellite was designed to operate for five years. [5]
AlSat-1 is built on the SSTL-100 platform. The onboard instrumentation consists of two banks with three Earth imaging cameras each that, in total, has a resolution of 32 meters in three spectral bands (NIR, red, and green). The imaging swath of the cameras is 600 km. The satellite was constructed in a fifteen-month time period by the British and Algerians, of which eleven Algerian engineers were trained by SSTL. [6] The satellite uses resistojets for propulsion, and butane as its propellant. The resistojets provide more than 20 m/s of delta velocity. [2]
This satellite carried the first Slim 6 Line Imager. The imaging opportunities for Algeria is one per day, for two or three days out of five days. During the first three months of operations, more than 80 images were transmitted back to Earth. [6] [2]
The Kosmos-3M was a Russian space launch vehicle, member of the Kosmos rocket family. It was a liquid-fueled two-stage launch vehicle, first launched in 1967 and with over 420 successful launches to its name.

CLEO - Cisco router in Low Earth Orbit, is an Internet router from Cisco Systems that was integrated into the UK-DMC Disaster Monitoring Constellation satellite built by Surrey Satellite Technology Ltd (SSTL) as a secondary experimental hosted payload, and launched into space with the satellite from Plesetsk on 27 September 2003.
The National Space Research and Development Agency (NASRDA) is the national space agency of Nigeria. It is a parastatal under Federal Ministry of Innovation, Science and Technology. The agency is based in the Nigerian capital city of Abuja in the Lugbe district and has a ground receiving station, among various other sites. In the past, it has cooperated in space technology with the United Kingdom, China, Ukraine and Russia. The agency has struggled with meeting its financial plans and some of its facilities are rundown. Despite this, the space agency is one of the most advanced space agencies in Africa, boasting of four satellites and very grand ambitions. Nigeria's satellites have been praised for their high-resolution images. NASRDA is host to one of UN-SPIDER's Regional Support Offices (RSO) in Africa.
The Disaster Monitoring Constellation for International Imaging (DMCii) or just Disaster Monitoring Constellation (DMC) consists of a number of remote sensing satellites constructed by Surrey Satellite Technology Ltd (SSTL) and operated for the Algerian, Nigerian, Turkish, British and Chinese governments by DMC International Imaging. The DMC provides emergency Earth imaging for disaster relief under the International Charter for Space and Major Disasters, which the DMC formally joined in November 2005. Other DMC Earth imagery is used for a variety of civil applications by a variety of governments. Spare available imaging capacity is sold under contract.
UoSAT-12 is a British satellite in Low Earth Orbit. It is the twelfth satellite in the University of Surrey series and was designed and built by Surrey Satellite Technology Ltd. (SSTL). It was launched into orbit in April 1999 on board a Dnepr rocket from Yasny Russia.
DMC International Imaging (DMCii) is the company that manages the Disaster Monitoring Constellation for the International Charter for Space and Major Disasters. It also sells satellite imaging services under contract and manages the operations of spacecraft such as UK-DMC1 & UK-DMC2. DMCII is a wholly owned subsidiary of Surrey Satellite Technology Ltd (SSTL). It recently struck a space deal with Beijing-based 21AT to build three high-resolution Earth observation satellites to map the growth of China.
SNAP-1 is a British nanosatellite in low Earth orbit. The satellite was built at the Surrey Space Centre by Surrey Satellite Technology Ltd (SSTL) and members of the University of Surrey. It was launched on 28 June 2000 on board a Kosmos-3M rocket from the Plesetsk Cosmodrome in northern Russia. It shared the launch with a Russian Nadezhda search and relay spacecraft and the Chinese Tsinghua-1 microsatellite.
Deimos-1 is a Spanish Earth imaging satellite which is operated by Deimos Imaging who commercializes its imagery directly but also has distribution agreements with other entities like Astrium GEO and DMC International Imaging.
UK-DMC 2 is a British Earth imaging satellite which is operated by DMC International Imaging. It was constructed by Surrey Satellite Technology, based on the SSTL-100 satellite bus. It is part of Britain's contribution to the Disaster Monitoring Constellation, which is coordinated by DMC International Imaging. It is the successor to the UK-DMC satellite.
UK-DMC or UK-DMC 1, also known as BNSCSAT-1, was a British satellite that formed part of the Disaster Monitoring Constellation (DMC). It was built by Surrey Satellite Technology, who operated it via DMC International Imaging on behalf of the British National Space Centre and later the UK Space Agency. It was launched alongside other DMC satellites on 27 September 2003, and retired from service in November 2011.
The Algerian Space Agency, was established on January 16, 2002 in Bouzareah, Algiers. The agency is in charge of the Algerian space program, and has flown five different satellites.
STRaND-1 is a failed 3U CubeSat developed by Surrey University's Surrey Space Centre (SSC) and Surrey Satellite Technology (SSTL). The 4.3 kg (9.5 lb) nanosatellite was launched into orbit on board a PSLV Rocket from India on February 25, 2013, Smartphones have flown in space before inside the International Space Station, and the computer from a PDA launched inside two Japanese CubeSats in 2006 and 2008.
BILSAT-1 was an Earth observation satellite designed and developed by TÜBİTAK Space Technologies Research Institute and produced in Turkey as part of the Disaster Monitoring Constellation (DMC) project in the context of a show-how program led by DMC International Imaging of Surrey Satellite Technology (SSTL).
Sir Martin Nicholas Sweeting is the founder and executive chairman of Surrey Satellite Technology Ltd (SSTL). SSTL is a corporate spin-off from the University of Surrey, where Sweeting is a Distinguished Professor who founded and chairs the Surrey Space Centre.

The National Space Program (PSN) horizons 2020 planned to put in place space infrastructures, and space systems and increase the specialized human resources in space technologies. Among the space systems planned in the PSN are Algeria's satellites, of which a significant number should be partly or totally integrated into the Algerian center for satellite development "CDS". CDS offers the technological environment for national competence to develop the future Algerian satellite systems. Algeria's objective is to make space tools a powerful instrument in national prosperity in the fields of earth observation, meteorology and communications.
EQUULEUS is a nanosatellite of the 6U CubeSat format that will measure the distribution of plasma that surrounds the Earth (plasmasphere) to help scientists understand the radiation environment in that region. It will also demonstrate low-thrust trajectory control techniques, such as multiple lunar flybys, within the Earth-Moon region using water steam as propellant. The spacecraft was designed and developed jointly by the Japan Aerospace Exploration Agency (JAXA) and the University of Tokyo.
