摘要
System, methods, and devices for a self-sustaining differential corrections network that employs roving reference devices (RRDs) as reference stations for improving positioning, navigation, and timing (PN&T) solutions for other enabled local roving and/or stationary receiving devices (RDs) are disclosed herein. The disclosed differential correction system enhancement leverages RRDs enabled for a non-global positioning system (non-GPS), secondary PN&T signal to characterize local errors. These local errors are then used by local RDs in combination with a signal to calculate an improved PN&T estimate for the RDs.
