The Anatomy of Our Network • Station Details • Planned ( 40+) • Installations prior to 8/04 (40) • Current spacing at 45 mile radius • Continuing densification to squeeze spacing down to 25 mile radius adding 30+ stations. • Recon (All)
The Anatomy of Our Network • Circuit Details • TCP/IP • 56/128/T1 Permanent Virtual Circuits on Frame Relay • Near Real-Time (<100ms) • Secure • Redundant
The Anatomy of Our Network • Network Operation Center • Windows based real-time Control and Integrity Monitoring software for a large network of reference stations. • Provides real-time statistics on GPS network performance and alarming for out of tolerance conditions. • Allows archiving and distribution of data • Hourly Zipped RINEX files
The Anatomy of Our Network • Control and Integrity Monitoring • Real Time from Software • Post Processed from Software • NGS/FSL daily processing
1 second data • 1 hour RINEX files • 24/7 • www.myfloridagps.com • RTK coming soon
Additional Applications Water Vapor Analysis Structural Monitoring
Sunshine Skyway Bridge – Tampa • 5 receiver suite • Other sensors being included • Installed 6/03 • Dames Point Bridge – Jacksonville • 4 receiver suite • Other sensors under consideration • Installation 1/04
Future Network Enhancements Real Time Kinematic
Future Network Enhancements Multi Sensor Monitoring System Bridge loading measurements, permanent deformation measurement, automatic observation of the bearing pads. Advantage: Flexible use of the total station for measurements with maximum precision in manual or automatic mode. Most importantly, the optical systems provide an independent check of the GPS measurements.
Concept-to-Reality • All sites located. • Installations complete at 100% of core locations. • Control Center is fully operational. • Additional installations in progress. • R&D of future enhancements to continue. • Inclusion into NGS CORS network.
