Lumir developed this new on-board computer in cooperation with Korea Aerospace Industries (KAI) for the CAS500-3 (technology verification satellite), which is scheduled to be launched aboard Korea’s fourth Nuri launch vehicle.

Lumir is the first Korean company to successfully develop and manufacture this onboard equipment, delivering superior performance and significant cost savings compared to competitors’ products. By integrating non-volatile NAND flash devices into the image data handling unit, storage capacity has been significantly increased, with data retention maintained even when the power is off.The image data handling unit of the satellite is a core device that receives high-speed, large-capacity data output from Earth observation sensors mounted on the satellite—such as SAR or optical cameras—then compresses and stores the data in real time, while also performing encryption and encoding for transmission to ground stations. Lumir has successfully developed and manufactured this satellite-mounted device domestically in Korea for the first time, breaking reliance on imported technologies. This achievement secures Lumir’s competitiveness by delivering superior performance and significant cost savings compared to foreign products.

Lumir, in collaboration with the Electronics and Telecommunications Research Institute (ETRI), developed and integrated this device for lunar exploration aboard Danuri (KPLO, the Korea Pathfinder Lunar Orbiter), Korea's first lunar probe. This device successfully demonstrated its performance by receiving BTS music videos transmitted from the Moon to Earth, achieving Technology Readiness Level (TRL) 9.

Lumir’s small SAR constellation system will comprise 18 satellites capable of capturing ultra-high-resolution images of key areas around the globe within an hour. This rapid data acquisition and delivery will enable real-time access to imagery, making the system especially valuable for time-sensitive applications such as surveillance, disaster response, and emergency management. Through LumirX’s advanced signal and image processing platform, SARDIP™, customers will be able to easily search for, purchase, and utilize SAR imagery. The platform will offer a suite of analysis tools, allowing users to extract meaningful insights and apply them efficiently across various industries.

This Ka-band antenna and data transmission device incorporates electronic beam steering antenna technology and software-defined radio technology as part of the Ka-band downlink system for satellites. It serves as a key component of data downlink systems within the satellite payload, supporting high-speed data transmission. The device enables system optimization through miniaturization, lightweight design, and single-unit modularization.

Primarily used in medium-sized and large satellites, it provides high torque performance and momentum conservation. By localizing the Control Moment Gyro controller, which had previously been imported for Korea’s domestic satellite industry, Lumir has gained a competitive advantage in both performance and cost.

CATIS™ is an ultra-high-resolution, small satellite imaging radar device independently developed by Lumir. It consists of three components: the radar signal transmission/reception device SCEU, an active phased array antenna SATA, and a data downlink antenna KaPA. This X-band imaging radar device is designed for small satellites weighing 150 kg, offering an ultra-high resolution of 0.3 m. It transmits wideband RF signals to the observation area while orbiting at an altitude of 500 km and receives the reflected signals to acquire Earth observation data.
