“…The U.S. Coast Guard has developed a number of LADGPS monitor sites that provide pseudorange corrections for GPS users in the area adjacent to the monitor sites [68]. Local, in this context, can apply to a radius of several hundred miles.…”

“…For example, including data from stations in the Southern hemisphere make s a significant difference from using Northern stations only [Lichten, 1990a]. Another application of global nets is to monitor the health or integrity of the GPS satellites, so this information can be quickly passed on to users worldwide, in real‐time or afterwards [Pietraszewski et al 1988; Kalafus, 1989].…”

The last four years have brought major changes to the practice of space geodesy, the most remarkable being the proliferation of precise techniques using the Global Positioning System to locate both points fixed to the Earth's surface and on moving vehicles. In their most accurate applications, GPS methods compare increasingly well with satellite laser ranging when measuring baselines of up to 1000 km. Meanwhile, the performance of laser systems has continued to improve, and the steady operation of laser sites around the world has extended the span of recorded observations to nearly one and a half decades of very high quality data.

“…Shipborne positioning has mostly been conducted up to now with a variety of land-based radio positioning systems, either in a stand-alone mode or in combination with ship's log and gyro and the Navy Navigation Satellite System (Transit). A real time inte- Spring 1988 grated navigation system, BIONAV, was successfully developed for this purpose 1241. In the early 1980s initial studies were conducted to assess the potential of Global Positioning System (GPS) to complement and eventually replace the above positioning systems.…”

The objectives of the Canadian Hydrographic Service with respect to GPS utilization are reviewed. A shipborne experiment undertaken in November 1986 and designed to test techniques developed to fulfill some of these objectives is described. The primary purpose of the experiment was to assess the performance of differential GPS positioning on a 10 m survey launch. The techniques utilized and results obtained on the launch are described. Additional tests conducted on a 38 m vessel are summarized. T14100 GPS receivers were used in various combinations of P code, C/A code, and different user dynamics modes. Carrier phase measurements were combined with pseudoranges to improve the accuracy. The reference positions were provided by two Atlas Polarfix systems and a Mini-Ranger Falcon 484 system. The external horizontal position accuracy of differential GPS was estimated to be 4.5 m at the 95 percent confidence level. Initial results obtained with a low cost attitude sensor are compared with GPS for both the launch and the 38 m vessel. The use of GPS to estimate heave motion is also discussed. Prospects of further improving GPS accuracy for shipborne positioning are mentioned in the conclusions.
