HawkEye 360 (HAWK) has signed a memorandum of understanding with Leonardo to integrate its radio-frequency, or RF, sensing capabilities with the Italian defense group's space service offerings, HawkEye said Tuesday.

The deal will support the development of "a sovereign, multi-sensor intelligence info-driven solution" for European customers, the space analytics company said.

Separately, HawkEye said it formed a partnership with passive surveillance firm ERA, which will serve as an international processing partner for the company's automated terrestrial and maritime radar products to strengthen defense surveillance capacity.

The collaboration will combine HawkEye's space-based signals intelligence, automated geolocation, and advanced RF analytics with ERA's offerings, the company said.

HawkEye shares were up 1% in premarket activity.
