A Global Navigation Satellite System (GNSS) aims to provide Earth-based position and navigation. Spaceborne GNSS receivers have become universal sensors for spacecraft navigation, especially in low Earth orbits (LEOs), often also supporting science endeavors or acting as dedicated science payloads.

Members of the Australian Department of Defence recently partnered with the Joint Navigation Warfare Center. JNWC’s mission is to enable positioning, navigation and timing superiority for the Department of Defense, interagency and coalition partners. The objective was to test GPS devices’ performance under simulated jamming conditions and enhance their resilience in contested environments.

On 30 July 2024, European navigators commemorated the 90th anniversary of Guglielmo Marconi’s first demonstration of microwave-guided navigation. In the Bay of Silence, off Sestri Levante, Italy, the historic vessel Leudo performed a blind navigation maneuver, crossing the space delimited by two buoys, guided by radio impulses transmitted from the shore. The operation was, in effect, a reenactment of radio pioneer Marconi’s demonstration of 30 July 1934.
