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.

High-power laser weapons targeting objects at 0.5 ~ 4.0km distances require optical components with sub-nm wavefront error precision. Our Company has successfully developed aspherical polishing and high-power laser coating technologies for Ø300 ~ 550mm optical components through defense project experiences. measurement technology 1) Laser Induced Damage Threshold(LIDT) - The evaluation to confirm the durability of optical components is called LIDT (Laser-Induced Damage Threshold), which is defined as "the maximum amount of laser radiation incident on an optical component when the expected probability of damage is zero" (ISO 21254). In other words, it represents the maximum intensity or power of laser that an optical component can withstand, making it a critical requirement in laser weapon systems. - Our company has established LIDT measurement technology and in-house facilities developed in accordance with ISO 21254 standards. When compared with LIDT test results from domestic and international companies during laser weapon system development, we have demonstrated measurement technology and accuracy that meets or exceeds industry standards. While overseas companies require more than one month for verification processes, our company can immediately provide reliable data through our LIDT system. 2) Cavity Ring Down Spectroscopy(CRDS) - When the reflectivity is 99.997%, this may not present significant issues in low-power laser applications. However, in high-power laser components, even the 0.05% of light that passes through the optical mirror can cause problems in vulnerable parts of the system, including rear optical instruments, bonded lenses, and control cables. Therefore, measurement and evaluation methods for high-reflectivity optical mirrors are extremely important. - Currently, the transmittance and reflectance of optical components are generally measured using spectrophotometers, but measuring reflectance levels of 99.5% or higher is not possible with this method. CRDS (Cavity Ring-Down Spectroscopy) technology is required to achieve measurement resolution beyond that of spectrophotometers, and our company has established this system to measure the reflectance of various optical components. This is a critically important technology for responding to high-power laser weapon system development requirements.

Radio interference on telecommunications / broadcasting satellites operating in and outside of the country may result in degradation and interference of telecommunications / broadcasting. This system searches the interfering sources by TDOA / FDOA.

The 200W High Power Amplifier is an L-band amplifier that delivers 200W output with a 60% duty cycle. It provides a gain of over 53 dB, with output flatness of 2 dB depending on the input signal level. At maximum output, it offers ACLR performance of -20 dBc. With a built-in output-stage bandpass filter (BPF), it achieves excellent harmonic suppression of -70 dBc. Built-in monitoring functions include output signal and temperature monitoring.
