Navigation

Navigation, derived from the Latin words "navis" (meaning  "ship") and "agere" (meaning "to drive") is the process of accurately determining the position and controlling the movement of a craft or vehicle along a desired course. This is accomplished by finding the navigator's position compared to known locations or patterns.

Early instruments used for determining latitude were the quadrant, (which measured the altitude of the polestar or the noonday sun,) the astrolabe and the sextant. Longitude was originally fixed using chronometers and tables showing yearly positions of celestial bodies. The first mariners to explore the world’s oceans developed standard ways of observing and recording their location, the routes they traveled, wind and water currents, and other useful facts. These records, logs, and journals made it possible find their way home and pass along their observations. Each successful voyage became a part of an expanding collection of reliable maritime information.

Modern navigation systems are part of a tightly coordinated and widely integrated transportation system in which each vessel must be responsible for staying on course, avoiding collisions, minimizing fuel consumption, and keeping on schedule. Modern navigation systems make use of many traditional tools, such as compasses, charts, instruments; but over the past century radio beacons, satellite networks and global positioning systems have been relied upon with increasing frequency to determine a ship’s position.

Ship compasses are usually stabilized by gyroscopes and installed in housing which properly compensates for the vessel’s motion. Charts are another essential navigational tool- position is fixed using charts of known locations in concert with instruments that calculate a vessel’s relative bearing. Dead reckoning is a method which relies on recording the accurate velocity calculated by gyroscopes and computer analysis of the vessel’s acceleration.

Teledyne TSS Adds Heave Capability to DMS 500

Teledyne TSS Adds Heave Capability to DMS 500

Following the successful launch of the new DMS-500RP motion sensor range in April, Teledyne TSS is expanding this product range with the introduction of the DMS-500H.

This new sensor provides heave measurement to complement the roll and pitch capabilities of the launch model. This is expected to be welcomed by a variety of users in the marine and offshore markets where there is known to be a need for a high accuracy sensor with these capabilities but at a lower cost and without the high performance subsea-rated housings that typify Teledyne TSS products. The new sensor can now provide heave measurement accurate to around 5 cm or 5 per cent

NOAA’s New Chart Supports Puerto Rico Maritime Economy

NOAA’s New Chart Supports Puerto Rico Maritime Economy

The Port of San Juan, which is experiencing a tremendous growth of maritime traffic and planning for more, received an additional economic boost today when NOAA debuted a new nautical chart that will make ocean-going vessel traffic safer and more efficient through San Juan Bay and the port area. 

 

 

“There is not only more traffic, but larger vessels are making San Juan their port call,” said Capt. John Lowell, director of NOAA’s Office of Coast Survey. “NOAA remains committed to providing the navigational products that allow the port to keep up with its level of growth.”
