TECHNOLOGY-

HYDROGRAPHIC SURVEY

GPS (USA), GLONASS (Russia) Galileo (Europe) Compass/Beidou (China-Regional) QZSS (Japan –regional) IRNSS (India –regional)

Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses—combined with other data recorded by the airborne system— generate precise, three-dimensional information about the shape of the Earth and its surface

characteristics.

• DGPS- Position Fixing.

• Sound Velocity Calibrator.

• ECHOSOUNDER – For Depth.

• LAPTOP –for Data Collection &

Interface.

• SOFTWARE- for Pre Processing,

Data collection, Editing, Analysis

& Reporting.
