GPS DATA COLLECTION SYSTEM UPGRADES. FINAL REPORT

The Tennessee Department of Transportation (TENNDOT) was the original DOT pioneer in the application of Global Positioning System (GPS) technology for developing Geographic Information System (GIS) base map networks. The feasibility of this technology application was demonstrated through a joint development program between TENNDOT and Rockwell International during the 1986-88 period. Following that, TENNDOT purchased GPS data collection equipment to continue GPS data collection in-house. TENNDOT's GPS data collection system had been designed before Selective Availability (S/A) became a reality in the GPS world, and has never had an effective differential correction capability. The primary objective of this contract was for Navstar Mapping Corporation (NMC) to upgrade TENNDOT's GPS data collection system by incorporating NMC's ROADMAPPER II (trademark) data collection system hardware and software. This upgrade took place during 1994 and TENNDOT's upgrade to the ROADMAPPER II (trademark) system configuration was completed in February 1995. A secondary objective was to explore and evaluate the feasibility of using the GPS data collected and processed by this new system to generate degree-of-curve and degree-of-slope data which could be used by TENNDOT to update the Tennessee Road Information Management System (TRIMS) Horizontal Alignment File and the TRIMS Vertical Alignment File. The feasibility of both of these techniques was successfully demonstrated under this contract. A third objective, completed in 1994, was to deliver and install Trimble's Universal Reference Station (URS) (trademark) software in the TENNDOT GPS Base Station and train TENNDOT user personnel. All contract objectives have been successfully completed. This report contains a summary of the major program tasks and milestones, a description of the new GPS data collection system and its current operating procedures, a copy of the Phase IIB degree-of-curve and degree-of-slope feasibility report, and a copy of the GPS Base Station User's manual.
