8.4 Discussion Global Navigation, Positioning, and Timing Systems

8.4 Discussion

Q All aspects of aviation are dependent on Global Navigation, Positioning, and Timing Systems (GNPT systems). GNPT systems are in the background of every aviation operation and are vital to the aviation industry. Review the following resources: • Aviation System Block Upgrade (ASBU) framework - Uniting Aviation (ICAO) (Links to an external site.) • The Aviation System Block Upgrades (ICAO) (Links to an external site.) • What is Positioning, Navigation, and Timing (PNT)? (US Department of Transportation) (Links to an external site.) • ASBU Elements (ICAO) (Links to an external site.) • Positioning, Navigation, and Timing (CISA) (Links to an external site.) • Cybersecurity Profile for the Responsible Use of Positioning, Navigation, and Timing (CSRC) (Links to an external site.) • PNT Program (Department of Homeland Security) (Links to an external site.) Respond to the following prompt: Identify how each sector of aviation (airlines, airports, aircraft manufactures, air traffic control, space operations, and remotely piloted aircraft systems) obtains and uses Global Navigation, Positioning, and Timing Systems. Discuss the capabilities and limitations of Ground Based Augmentation Systems (GBAS), Satellite Based Augmentation Systems (SBAS), and Aircraft Based Augmentation Systems (ABAS) ________________________________________ Requirements for discussion posts: • Write a minimum of 200 words. • Use at least one outside reference source cited in current APA format. Requirements for discussion replies: • Respond to at least two of your classmates • Write a minimum of 100 words. • Use at least one outside reference for each response, cited in current APA format.

There is obtainment and utilization of Global Navigation, Positioning, and Timing Systems by each sector of aviation by gaining access from GPS.gov (What is positioning, navigation and timing (pnt), 2017). This is because there are different segments prepared by GPS.gov to ensure that customized and required services can be provided to different sectors of aviation (What is positioning, navigation and timing (pnt), 2017).
