This inquiry summarizes test and measurement methods and equipment to characterize the resiliency of various global navigation satellite systems, including the Global Positioning System (GPS) coarse acquisition code; P(Y) code; Selective Availability Antispoofing Module; GPS Block III M-code; and Link 16 multimodal position, navigation, and timing systems. In addition, basic working principles; spectral alignment; and conducted/radiated testing with multi-antenna configurations, including controlled reception pattern antenna tests, standard GNSS test parameters, and additional PNT systems such as the Southern Positioning Augmentation Network Satellite-Based Augmentation System are reviewed.
What are good methodologies for measuring the resilience of global navigation satellite systems?

The Global Positioning System (GPS) is a constellation of orbiting satellites that provides position, navigation, and timing data to military and civilian users globally. The system is operated and controlled by Space Delta 8, a component of U.S. Space Force, headquartered at Schriever Space Force Base, Colorado.
