Global Navigation Satellite Systems

摘要

eLoran is not a panacea. It can be one of many technologies forming a global PNT 'system of systems'. Others could include everything from standard inertial navigation systems to automatic, visual, radar and celestial navigation. This approach provides redundancy, resilience and integrity. If one PNT system is degraded or unserviceable the others can pick up the slack. Having several technologies providing PNT enhances the overall accuracy and coverage of the user's timing and navigation data.
