GPS

Basics

• An abbreviation for Global Positioning System
• Was origionally less accurate civilians due to a system of Selective Availability, but this system was later stopped via software on midnight on May 1, 2000, and Block-III satellites will be physically incapable of it, so this will remove it in hardware over time
• A USA Owned and Run Navigational Satellite Constellation
• The first system of it's kind from SECOR which was a survey system adapted into a crude SATNAV system to Block-1 of GPS
• Worldwide Coverage (Albeit with lesser coverage in certain areas, and this becomes less of a problem with each new launch)
• Is also augmented for use in certain regions using GSNS Augmentation methods
