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.
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. Testing it in an anechoic chamber that mimics contested and limited GPS conditions enabled the team to uncover insights that can enhance its resilience.
The JNWC, known for its expertise in navigation warfare, provided optimal testing conditions for this assessment. The specialized chamber allowed them to test the DAGR’s performance in a jamming environment, generating data that can inform the device’s warfighting effectiveness.
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 collaborative initiative enhances GPS navigation and timing resilience, and provides a model for international cooperation in addressing security threats.
