StriX α [Synspective]
StriX α is Japanese synthetic aperture radar satellite built by Synspective as a demonstrator for their planned 25 satellite constellation. It features an X-band synthetic aperture radar.
StriX α is a 150 kg satellite, larger than the planned 100 kg operational satellites. The satellite 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.
The launch of the StriX α prototype was originally planned for 2020 on an Arianespace Vega booster on a shared mission. The lauch was moved to a Rocket Labs Electron KS in late 2020. The Electron payload fairing required modifications to accomodate the satellite.
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.
