Payload faces final design review
South Korea’s space agency will conduct a three-day detailed design review beginning on the 28th for the payload aboard the first satellite in the Korean Positioning System, or KPS.
The meeting at the Korea Aerospace Research Institute in Daejeon will bring together officials from the land and oceans ministries, the Korea Coast Guard and participating research organizations. They will assess whether the payload’s design meets required functions and performance standards and whether the project is technically ready to proceed to manufacturing, assembly and testing.
The payload, which will generate navigation signals, is a core component of the planned satellite navigation network. The review is considered the final design checkpoint before construction of a flight model. A preliminary design review was completed in February 2025.
First launch delayed to September 2029
The development schedule for the first KPS satellite has been extended by 20 months. Its launch, originally planned for 2027, is now scheduled for September 2029 because additional time is needed to design and verify the navigation payload.
Kim Jin-hee, who leads the satellite division at the Korea AeroSpace Administration, said government agencies and research organizations would closely examine the design and work to complete additional reviews scheduled this year without disrupting the broader KPS program.
Eight satellites planned by 2035
KPS is intended to provide highly precise positioning, navigation and timing information around the Korean Peninsula. The 14-year program began in 2022 and has a budget of 3.72345 trillion won.
The space agency is maintaining its goal of deploying eight satellites by 2035. A detailed design review for the first satellite as a whole is planned for next month, followed in November by an integrated review covering the KPS system, ground infrastructure and user systems.
