The combined effort brought together experts from both nations. Personnel from the Australian Joint Positioning, Navigation, and Timing Directorate worked alongside JNWC personnel to evaluate the Defense Advanced GPS Receiver.

The DAGR, a widely used GPS device by both U.S. and allied forces, plays a critical role in land, sea and air navigation. By subjecting it to an anechoic chamber that mimics contested and limited GPS conditions, the team aimed to uncover insights that could enhance its resilience.

The JNWC, known for its expertise in navigation warfare, provided the ideal setting for this assessment. Their commitment to enabling PNT superiority for the Department of Defense, interagency, and coalition partners drove the rigorous evaluation process. The specialized chamber allowed them to test the DAGR's performance in a jamming environment, generating useful data that informed the device's warfighting effectiveness.

Space-based capabilities like GPS and other forms of PNT are fundamental to all joint military operations, as highlighted in the National Security Strategy, National Defense Strategy and National Military Strategy. This reliance on these capabilities extends to essential daily activities, from navigation and financial transactions to infrastructure reliant on these space-based technologies. However, adversaries are actively developed counterspace capabilities, including GPS jammers, to disrupt these advantages. The collaboration between the U.S. and Australia directly addresses this threat.

By evaluating the DAGR's resilience, the team explored potential solutions, including antennas that enhance jamming resilience. The findings from this project will be shared with other coalition partners, further strengthening the collective space resilience of allied forces.

This combined effort not only enhances GPS navigation and timing resilience but also exemplifies the power of international cooperation in addressing security threats. As the world faces evolving challenges, partnerships like these remain essential for maintaining an edge in contested environments.

The JNWC's mission is to enable PNT superiority for the DoD, interagency and coalition partners, serving as the DoD's Center of Excellence for NAVWAR. Under the authority of the Combined/Joint Force Space Component commander the center provides subject matter expertise, operational support and analysis to combatant commands in support of U.S. Space Command's mission to plan, execute and integrate military space power. Additionally, the JNWC conducts assessments to enhance NAVWAR capabilities and advises on policy and preparedness.
