From: Performance of an ultrasonic telemetry positioning system under varied environmental conditions
Conceptual model of factors influencing the performance of an ultrasonic positioning system. Positioning system performance metrics (a) are directly influenced by various user-controlled and environmental variables (b), which in turn are influenced by a number of contributing factors present at a study site (c). Variables measured for this study are bold. Those in gray could not be reliably measured so were not considered in statistical models.
