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.

In high-performance applications, the debate over quartz and silicon MEMS inertial sensors rages on, but guest columnist David Gaber of Epson makes the case for why products from OEMs versus integrators are superior.

One of the biggest challenges for satellite based positioning is mitigating the effects of multipath interference and non-line-of-sight (NLOS) signals, particularly in urban environments.

A: Receiver Autonomous Integrity Monitoring (RAIM) and Advanced RAIM (ARAIM; known more generally as Solution Separation RAIM, or SS-RAIM) were originally designed to detect, alert and (where possible) exclude faulty measurements caused by Signal-in-Space (SIS) failures.
