Uganda Prepares First Satellite for ISS Launch
Uganda has reached a milestone in its space technology ambitions with the completion of its first satellite, PearlAfricaSat-1. The project began in April 2020 when three Ugandan graduate students—Edgar Mujuni, Derick Tebusweke, and Bonny Omara—were sent to Japan to train in satellite design, manufacturing, and testing. Their participation was part of a global program initiated in 2015 by the Kyushu Institute of Technology, aimed at fostering satellite development skills in emerging space nations.
On May 10, 2022, the team finalized work on the 10-cubic-metre satellite and handed it over to the Japan Aerospace Exploration Agency (JAXA) for final testing. Dr. Monica Musenero, Uganda’s Minister of Science, Technology, and Innovation, stated, “These students completed the development of this satellite, and this morning we remotely participated in an event at the prime minister’s office where the government of Uganda, represented by the nation’s ambassador in Japan, handed over this satellite to the Japan Space Agency to finalise some tests and those tests will be done in about five days and then it will await launch together with other satellites by NASA in August.”
Following JAXA’s testing, the satellite will be transferred to NASA for transportation to the International Space Station. From there, it is scheduled for deployment into low Earth orbit in August. Once operational, PearlAfricaSat-1 will deliver research and observation data across six key domains: weather forecasting; land, water, and mineral mapping; agricultural monitoring; infrastructure planning; border security; and disaster prevention.
The satellite’s primary mission is driven by a multispectral camera payload capable of producing images with approximately 20-metre resolution. This capability will support water quality assessments, soil fertility studies, and land use analysis. In addition, it will provide data critical to Uganda’s oil and gas sector, particularly for monitoring the East African crude oil pipeline. Remote sensing data from the satellite will enhance weather prediction accuracy, aiding in the early detection of landslides and drought conditions.
After deployment, Uganda’s ground station will monitor the satellite’s health for several days before mission operations commence. This ground segment forms part of a broader strategy announced in 2019, when the Ministry of Science, Technology, and Innovation allocated funds for capacity building in satellite development. The plan includes launching a second, domestically built satellite by the end of 2024, with an emphasis on developing local engineering expertise.
Preparations for the PearlAfricaSat-1 mission have also spurred infrastructure initiatives. Musenero indicated that preliminary assessments are underway to redevelop the Mpoma earth satellite station. While full redevelopment is expected to be a significant undertaking, interim measures involve installing sensor terminals in existing structures. The same three engineers who built PearlAfricaSat-1 will contribute to this installation effort. Local sources report that the government has earmarked USD 200,000 (about Shs 716.3 million) to improve infrastructure at Mpoma.
The Mpoma station will operate under the joint oversight of the Uganda People’s Defence Force (UPDF), Uganda Telecom Limited (UTL), and the Ministry of Science, Technology, and Innovation’s space program. This collaboration underscores the strategic importance Uganda places on its nascent space capabilities, both for civilian applications and national security.
Uganda’s entry into satellite operations aligns with a broader trend of emerging nations investing in space technology to address domestic challenges. By leveraging orbital assets for environmental monitoring, resource management, and disaster mitigation, such programs can deliver tangible benefits while fostering technical expertise within the country. The PearlAfricaSat-1 project represents not only a technological achievement but also a foundation for future aerospace engineering in Uganda.
