230mm Optical System

Our 230mm optical system was designed as a payload of our 16U CubeSat platform. It is capable of in orbit reconfigurable GSD up to 2.5m and spectral bands up to 12 bands at 50km swath. The capacities of its collection and rapid revisit provide repeated images of large areas for the purpose of conducting automated change detection data.


Our 230mm optical system can be integrated with any platform. We can also assist in integrating this payload with any satellite platform for optimal performance.

Please contact us if you are interest in our product. All our products can be customized according to requirements.
