Harbinger (ICEYE X3)

Harbinger is proof-of-concept prototype for York Space Systems' S-class satellite bus. The demonstration mission features the ICEYE X3 X-band SAR payload.

The Harbinger mission features York's S-class platform utilizing the enhanced power subsystem offering up to 3,000 W peak for payload operations, a field-effect electric propulsion (FEEP) system, and high rate laser communications terminal.

As a demonstration payload Harbinger features ICEYE's ICEYE X3 X-band SAR instrument with a resolution of 1 m, based on the ICEYE X2 mission, BridgeSat�s optical communications payload and Enpulsion of Austria�s Field Emission Electric Propulsion. Also a low-resolution optical camera is on board.

The flight of the Harbinger satellite was sponsored via the U.S. Army Space and Missile Defense Command for a launch in the framework of the Space Text Program (STP).

Harbinger was launched in May 2019 on an Electron KS rocket on the STP-27RD mission. The radar payload early in the mission had issues with payload to bus communications, which were reportedly solved.
