Dondra Head Lighthouse
Dondra Head Lighthouse is a lighthouse located on Dondra Head, Dondra, the southernmost point in Sri Lanka and is Sri Lanka's tallest lighthouse, and also one of the tallest in South East Asia. Dondra Head lighthouse is operated and maintained by the Sri Lanka Ports Authority. The lighthouse is near the village of Dondra, and is approximately southeast of Matara. The name Dondra is a synonym for "Devi-Nuwara" in the local Sinhala language, "Devi" meaning "Gods" and "Nuwara" meaning "City". Dondra is therefore derived to mean "City of the Gods". History Dondra Head Lighthouse was designed by Sir James Nicholas Douglass, with construction, by William Douglass of the Imperial Lighthouse Service, commencing in November 1887. All the building materials including the bricks and steel were imported from England. The granite rock was supplied from quarries at Dalbeattie in Scotland and Penryn in Cornwall. The lighthouse was completed and commissioned in March 1890. The combine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses Completed In 1889
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Differential Global Positioning System
Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS for GPS can increase accuracy by about a thousandfold, from approximately to . DGPSs consist of networks of fixed position, ground-based reference stations. Each reference station calculates the difference between its highly accurate known position and its less accurate satellite-derived position. The stations broadcast this data locally—typically using ground-based transmitters of shorter range. Non-fixed (mobile) receivers use it to correct their position by the same amount, thereby improving their accuracy. The United States Coast Guard (USCG) and the Canadian Coast Guard (CCG) each run DGPSs in the United States and Canada on longwave radio frequencies between and near major waterways and harbors. The USCG's DGPS was named NDGPS (Nationwide DGPS) and was jointly administered by the Coast Guard and the U.S. Departmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chance Brothers
Chance Brothers and Company was a glassworks originally based in Spon Lane, Smethwick, West Midlands (formerly in Staffordshire), in England. It was a leading glass manufacturer and a pioneer of British glassmaking technology. The Chance family originated in Bromsgrove in Worcestershire as farmers and craftsmen, before setting up business in Smethwick in 1822. Situated between Birmingham and the Black Country in the agglomeration of the Midlands industrial heartland, they took advantage of the skilled workers, canals and many advances that were taking place in the industrial West Midlands at the time. Throughout its almost two centuries of history many changes affected the company which, now privatised, continues to function as Chance Glass Limited, a specialised industrial glass manufacturer in Malvern, Worcestershire at one of its small subsidiary factories. The social and economic impact of the company on the region is the subject of a project sponsored by the Heritage Lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperradiant Fresnel Lens
Hyper-radial or hyperradiant Fresnel lenses are Fresnel lenses used in lighthouses. They are larger than "first-order" lenses, having a focal length (radius) of 1330 mm (52.36 inches). The idea was mentioned by Thomas Stevenson in 1869 and first proposed by John Richardson Wigham in 1872, and again proposed by Thomas Stevenson in 1885 (infringing Wigham's patent). The hyper-radial lens was made in 1885 by the F. Barbier Company in Paris as a test lens for the lighthouse illumination trials then going on at the South Foreland Lighthouse in the United Kingdom (UK). Chance Brothers Glass Company made their first hyper-radial lens in 1887 in the UK. These lenses were originally named biform, and later triform and quadriform lenses, by Wigham. Thomas Stevenson used the term hyperradiant lens, and later they were renamed the hyper-radial lens by James Kenward of the Chance Brothers Glass Company. The hyper-radial Fresnel lenses were the largest ever put into use and were installe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It was further modernised in 2000, with the introduction of a Differential Global Positioning System (DGPS) and is computer linked to the other major lighthouses around the country.
