Harbinger (ICEYE X3)

Harbinger [York Space Systems]

Harbinger is proof-of-concept prototypes for a 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 10 m, inherited from the ICEYE X2 mission, BridgeSat’s optical communications payload and Enpulsion of Austria’s Field Emission Electric Propulsion.

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.
