Artificial satellites are categorized into three main types: communication, positioning, and Earth observation satellites. Additionally, Earth observation satellites are divided into optical and Synthetic Aperture Radar (SAR) types.

Among these, we are involved in the development, manufacturing, and operation of SAR satellites. Our satellites, which are classified as Earth observation satellites, observe terrain and the shape of structures.（*What is SAR？）

In building a constellation, factors such as the number of satellites, their resolution, and latency (including order processing times) are crucial.
Equally important is the choice of orbit for deploying satellites, especially when providing datasets for time series analysis and change detection, which are distinctive capabilities of SAR satellites.

Traditional large SAR satellites are designed with a focus on maximizing coverage with each individual satellite, using a sun-synchronous orbit to ensure global reach.This orbit enables them to pass over the same area at consistent local solar times, typically every few days.

On the other hand, with smaller SAR satellites, it is feasible to develop and launch multiple satellites for the equivalent cost of one large satellite. By deploying these smaller satellites into sun-synchronous orbits, global coverage can be achieved more effectively. The currently operational StriX-β and StriX-1 satellites, deployed in sun-synchronous orbits, enable consistent monitoring of the same area.
