As reentry takes place, the V part of the telemetry is transmitted back to the GS ground station which shows exactly where the rocket is located per unit time. According to the system calculus, the rate of change is qualitative analyzed, not quantitative. The simplicity and reliability of this system is within the incorporation into the rockets already existing telemetry package. Data is sent to the ground station for resolution. As the system uses existing parts and components, no GPS or complicated systems are used.
