SPACE CENTER, Miss.
-- A group of government, industry and academic experts from across
North America will gather at The University of Southern Mississippi
Gulf Coast in Long Beach, Miss., later this month to focus on Global
Positioning Systems (GPS) technology in maritime applications.
Hosted by the
Southern Miss Hydrographic Science Research Center based at Stennis
Space Center, this workshop is scheduled for March 16-18 and is
co-sponsored by the Office of Naval Research and the Naval Oceanographic
continue to focus on the themes of carrier phase GPS navigation
for hydrographic surveys and seamless vertical datums," said
Sunil Bisnath, a researcher with the Hydrographic Science Research
Center. "Fundamental to all aspects of hydrography, or charting
of the sea floor, is accurate 3-D positioning," Bisnath said.
vertical datum" refers to continuity between various sea-based
chart depths and land-based map heights.
One of the
fastest emerging trends in hydrographic surveying is the use of
the vertical component of what is generally known as Real Time Kinematic
Global Positioning System (RTK GPS) to determine real time precise
vessel location and water level corrections for more accurate charts.
RTK GPS exists when measurements are supplied from a land base station
of known location to a moving receiver.
at the workshop will include representatives from private industry,
academia and government, including Southern Miss, the Naval Oceanographic
Office, the National Oceanic and Atmospheric Administration, and
the U. S. Army Corps of Engineers.
