GPS Base Station

SoumiNet at IAGT

The Institute for the Application of Geospatial Technology (IAGT) has completed the installation of a Geodetic GPS base station on its property dedicated to an international scientific study of ways to improve weather forecasting. IAGT has joined the ranks of other top schools involved in this study, such as Universities of Connecticut, Arizona, Colorado, MIT and Purdue. The Navstar Consortium (UNAVCO)—funded by the National Aeronautics and Space Administration (NASA) and the National Science Foundation (NSF) is installing the equipment and coordinating the study.

GPS technology can be used in atmospheric study based on the functionality of GPS. As many of our readers know, GPS is based on time and the “triangulation” of up to 24 satellites to a location on the earth’s surface. The accuracy of measuring the location of a position on the ground is determined by the number of satellites that can “see” it and the time it takes for a GPS signal to reach it. Delays in the time it takes to receive a GPS signal will falsely increase the estimated distance between the ground location and the GPS satellite, thus decreasing the accuracy of the GPS location information. By having accurate pressure and temperature readings at the same location as a GPS base station, SoumiNet researches can determine amounts of water and other factors in the atmosphere that are slowing down GPS signals.

Water vapor in the atmosphere is highly variable. It is an essential component in determining what the weather will be like on any given day. Yet water vapor is poorly measured over large areas. This study will improve knowledge of the water vapor and promises to make major improvements in short-term weather forecasting. A GPS research group from the National Oceanic and Atmospheric Association (NOAA) Forecast Systems Laboratory is already analyzing the GPS data from the existing international network. IAGT will add to the scientific understanding of weather by participating in this project.

IAGT also hopes to supply the GPS base station data to advanced GPS users in the community, allowing them to improve the accuracy of the data they collect. This has the potential to improve the speed and accuracy of things like boundary surveys, construction site planning, and the general collection and asset inventory. IAGT also hope to make available RTK services using cellular technology in the future.
