GNSS has paved the way for a multitude of applications in the field of Positioning, Navigation, and Timing (PNT). Different methods and techniques like Standard Positioning Service (SPP/SPS) using a single or dual frequency receiver, Real Time Kinematic (RTK) using a Base-Rover architecture, and Precise Point Positioning (PPP) using a single dual frequency receiver and augmentation information has increased the level of accuracies and precision both in static and dynamic operations. Currently, usage of internet-based RTK positioning services has increased as the method conveniently provides improved accuracy in real-time. But network security threats and connectivity issues are points of concern in many applications, specifically for strategic sectors including Test Range. In such cases, Post Processing Kinematic RTK (PPKRTK) is a possible option. This study explores a comparative analysis of the potential of PPK-RTK with conventional RTK and SPP positioning for Test Range applications using compact, low-cost, dual frequency (CLD), multi-constellation GNSS modules. The results show a centimeter to decimeter-level precise position solution; the results would be useful in enhancing the confidence in using PPK systems for various applications, where the real-time connectivity between the RTK Base and Rover poses cyber security threats.
