LOTUSat-1 earth observation satellite uses SAR (Synthetic Aperture Radar) sensor to capture high resolution images in all weather conditions. Its image data will partly adapt the urgent needs on imagery sources, providing accurate and timely information in responding to and mitigating the impacts of natural disasters and climate change, supporting natural resources management and environment monitoring, serving socio-economic improvement.
In the meeting, attendees reviewed all the system requirements of the satellite system, helping to clarify necessary inputs for its design lately. LOTUSat-1 satellite is expected to operate on Sun Synchronous Orbit (SSO) at the altitude of approximately 500 kilometers, providing images at 3 modes: Spotlight, StripMap and ScanSAR, with spatial resolutions: smaller than 1 meter, smaller than 2 meters and smaller than 16 meters, respectively. The designed lifetime of the satellite is 5 years.
