GhanaSat-1 is the first Ghanaian satellite to be launched into space.[3] It was designed and built in two years in conjunction with the Kyushu Institute of Technology's Birds-1 program, which has the goal of helping countries build their first satellite.

The satellite can take images, collect atmospheric data, measure space radiation, and transmit uploaded audio. GhanaSat-1 was launched to the International Space Station (ISS) on a Falcon 9 rocket. It was released into space from the NanoRacks CubeSat Deployer on the ISS on 7 July 2017 and is being used to monitor environmental activities along Ghana's coastline.

Background

Japan supports non-spacefaring countries in building their first satellite through the Joint Global Multi-Nation Birds satellite program, sponsored by Kyushu Institute of Technology (KIT), which is a cross-border interdisciplinary satellite project for non-spacefaring countries. Four guest countries participated in the Birds-1 program: Ghana, Mongolia, Nigeria, and Bangladesh. GhanaSat-1 was the first Ghanaian satellite launched into space.[4]

Design and development

GhanaSat-1 was assembled and tested by three students at All Nations University.[5] The five 1U CubeSats, four built by the guest countries and one by KIT, were all identical in their design.[6] The two-year period spanning the development, construction, launch and operation of the satellites engaged three university students from each of the five participating countries.[7] The satellite cost about US$500,000 to manufacture and launch.[8]

GhanaSat-1 is a small satellite, weighing around 1 kilogram (2.2 lb).[5] Power is generated from solar cells and stored in batteries.[4] The satellite is cube shaped and measures 10 centimetres (4 in) on each side.[9] The satellite carries low- and high-resolution cameras that will be used to take pictures of Ghana and monitor the country's coastline. It will also broadcast the national anthem of Ghana. The satellite has the ability to receive requested songs from the ground and transmit them from space.[5] Finally, the satellite will be used to measure the effects of radiation in space on commercial microprocessors.[5]

GhanaSat-1 was given to the Japan Aerospace Exploration Agency (JAXA) on 9 February 2017, and was then transferred to the National Aeronautics and Space Administration (NASA) on 12 February.[5] The GhanaSat-1 Birds designation is Birds-G.[10]

SpaceX launched the satellite on its CRS-11 mission to the International Space Station on 3 June 2017. The satellite was carried in a Dragon spacecraft on a Falcon 9 rocket, launched from NASA's Kennedy Space Center Pad 39A. This was the 100th launch from Pad 39A and the first time SpaceX reused one of its Dragon capsules.[1] This mission also carried CubeSats from Japan, Bangladesh, Nigeria, and Mongolia.[10] The satellites from Bangladesh (BRAC Onnesha) and Mongolia (Mazaalai) are those countries' first satellites.

Cubesats being launched from the Kibō module of the International Space Station

GhanaSat-1 was launched by a Japanese astronaut from the NanoRacks CubeSat Deployer, located in the Japanese Kibō module of the International Space Station, on 7 July 2017.[10] The satellite launch was broadcast live and watched by over 400 people at All Nations University.[3] The satellite orbits the Earth at an altitude of 400 kilometres (250 mi) and at an inclination of 51.6 degrees. It orbits the planet every 92 minutes at a velocity of 7.67 kilometres per second (17,200 mph).[11][8]

Operations

The satellite is primarily a technology demonstrator and Earth observation satellite. The Ghana scientists will take images of the Ghanaian coastline for cartography. The director of Space Systems Technology Laboratory at All Nations University, Richard Damoah, said the satellite would "...also help us train the upcoming generation on how to apply satellites in different activities around our region. For instance, [monitoring] illegal mining is one of the things we are looking to accomplish."[3] The satellite communicates with seven ground stations: one in each of the countries participating in the Birds-1 program, and one each in Thailand and Taiwan.[4]

Future work

The university plans to coordinate with the government to build GhanaSat-2 and GhanaSat-3. The primary objective of GhanaSat-2 is to monitor water pollution, illegal mining, and deforestation.[12][13] Japan's work with non-spacefaring countries will continue with Birds-2 in 2018 with participation from the Philippines, Bhutan, and Malaysia.[4]
