StriX 1, ..., 25

StriX α [Synspective]

StriX 1 to 25 are Japanese synthetic aperture radar satellites built by Synspective for their planned 25 satellite constellation. They feature an X-band synthetic aperture radar.

The 100 kg StriX operational satellites are more light weight than the 150 kg StriX α and β prototypes. The satellites features two deployable panes, one side carrying solar cells, the other carrying the X-band radar antenna.

The StriX satellite constellation can target data with a ground resolution of 1-3 m, single polarized (VV), and a swath width of more than 10-30 km. The StriX observation modes are Stripmap and Sliding Spotlight mode and each satellite has an SAR antenna that is 5 meters in length and stowed during launch. The simple design of the satellites allows for affordable development of the constellation.

Synspective is planning a constellation of 25 satellites called StriX, comprised of 100-kilogram satellites capable of imaging at a resolution of one to three meters. By 2022 the company plans to have six satellites in orbit. The company has not set a date by which it hopes to achieve 25 satellites.
