Dredging Research Program: Investigation of Real-Time Differential GlobalPositioning System (DGPS) Data Link Alternatives

摘要

This report describes real-time data broadcast systems for the transmission ofdifferential GPS (DGPS) data to mobile users. It considers broadcast systems for the meter level DGPS, which require data rates of 50 to 100 bits per second; and it considers broadcast systems for decimeter level DGPS, which require small commensurate with operation on a 16-ft skiff. It considers broadcast systems of
