ADLER 1 (Austrian Debris Detection Low Earth (orbit) Reconnoiter) is an Austrian In-Orbit Demonstration of space debris detection from a 3U CubeSat using multiple sensors. It is developed by SPIRE and WF (stereichisches Weltraum Forum , Austrian Space Forum) in partnership with FINDUS Venture GmbH.

The ADLER-1 satellite is based on Spire Global's Lemur-2 cubesat and features customized experiments instead of the standard Lemur payload.

The satellite carries two Instruments:

  • APID (Austrian Particle Impact Detector), consisting of two deployable piezoelectric sensor wings, with 12 units of ca. 60 × 65 mm each and a total sensor surface: ca 865 cm2
  • PL2/CW Radar, an 1 Watt CW Radar operating at 78 GHz, of automotive-heritage to detect debris objects withing 50 meters.

ADLER 1 was launched in January 2022 on a shared LauncherOne rocket.
