Pitkä artikkeli, joka kertoo hieman mitä GPS-satelliittien M-Code:lla päivitys tuo. (GPSIII-satelliiteista IIIF:ksi).
GPS IIIF satellites will build on GPS III capabilities by adding Regional Military Protection capability and three secondary payloads. Regional Military Protection concentrates even higher M-Code signal power in a targeted region—allowing receivers to operate more than 10 times closer to a jammer than with the military signals operational today.
One new secondary payload is a Search and Rescue payload to geo-locate emergency transponders and provide coordinates for rapid assistance to distressed users. Another new payload is a Laser Retroreflector Array that enables independent ranging and ephemeris verification from surveyed ground sites worldwide. The third payload is the redesigned Nuclear Detonation Detection System.
Brown: The new capabilities will revolutionize GPS command and control from the point of view of availability, reliability, accuracy and cybersecurity. Modernization will enhance mission management and mission-data processing to shift the focus of operations from satellite command and control to basic, user-oriented effects-based operation. The key capabilities for our warfighter were providing pathfinding information to protect the system against cyber attack.
We’ll also see improved availability of military accuracy, especially in jammed environments. We also are increasing position accuracy and enhancing the system integrity to ensure that our warfighters have the most robust information to make decisions when they matter the most.
