| Abstract | The High Accuracy-Nationwide Differential Global Positioning System (HA-NDGPS) program focused on the development of compression and broadcast techniques to provide users over a large area wit very accurate radio navigation solutions. The goal was achieve 0 cm in real time over 322 kilometer baselines. The focus of the Phase II effort was on several aspects of HA-NDGPS to refine the navigation solution and demonstrate its usefulness. To that end this report provides a description and analysis of these tasks as well as conclusions reached. The tasks include: provide a basic examination of the utility of using data from two reference stations; develop and implement a prebroadcast integrity algorithm; develop interface software for various brands of GPS receivers; rewrite the modular software; evaluate lower baud rate messages more than once every epoch; demonstrate driver analysis based on the HA-NDGPS navigation solution; examine multipath noise levels at the Hagerstown, MD facility. The approaches and results provided in this report offer significant insight into the success of the overall HA-NDGPS program and its approach to meeting the needs of many users. |
