Abstract
A calibration system utilizing existing location techniques for a global radio telecommunication system 10 autonomously calibrates the communication system's location system by routing precision location data through system 10. Calibration reduces system errors by allowing time slots to remain narrow. The precision data is carried by existing commands throughout the system to measure location errors inserted by satellites 12. A gateway 16 compiles and evaluates received calibration data and determines when to update all gateways 16 with new satellite variance data tables 435. The calibration system provides early warning of degradation of system components and long-term analysis of system performance.
