This is a set of 42 photographs taken during 4th Field Survey Squadron’s deployment on Operation ARIGHT 93 in North Queensland from the 30th of August to the 8th of October 1993. The Survey Field Completion area of operations was Weipa near the top end of the Cape York Peninsula. Survey parties conducted field checking of topographic maps covering Bamaga, Heathlands, Weipa, Lockhart River and Strathgordon in Perentie 110 Series Survey variant FFR Land Rovers. Hand-held Trimble and Magellan GPS receivers were used to assist with navigation and to position remote isolated features. Three Bell Kiowa LOH helicopters provided by 162 Recce Sqn supported field checking operations. Supplementary and Vital Asset Protection photography was taken by air camera operators in AAAvn Nomad aircraft from 173 Survl Sqn fitted with an RC10 aerial camera.This is a set of 42 photographs taken in 1993 durin8g 4th Field Survey Squadron’s deployment on Operation ARIGHT in North Queensland.

A marine foghorn gives an audible navigational signal to warn vessels of dangers, hazards and the presence of other vessels in fog conditions. The foghorn signal is a series of long and short sounds with short or long pauses between them. These common signals conform to a code called the International Regulations for Preventing Collisions at Sea and provide such information as whether the vessel is under sail or motor, large or small, aground or at anchor. The designs of foghorns vary but they all use a column of air to make a loud sound. Some use vibrating plates or metal reeds, others force air through holes in a revolving cylinder or disc, sounding like a siren, and some use a clockwork mechanism to open the valves that let the air into the horn. They are usually built to meet particular specifications e.g. U.S.C.G. (US Coast Guard). This Tyfon plunger foghorn has a horizontal handle attached to a vertical rod that moves up and down inside a cylinder. When the handle is plunged down, in a similar way to a bicycle pump, the air is forced out of the bottom of the cylinder into a pipe with a bell-shaped horn on the end, making a loud, low sound. The wider base of the cylinder helps to keep it stable. The original type Tyfon foghorns were manufactured in about 1910 by Kochums Mechanical Workshop (Kockums Mechanical Werkstad, Ltd.), Malmo, Sweden. The company was established in 1840, became a Limited company in 1866, and established a shipyard at the Port of Malmo, Sweden, in 1870. The civilian ship production in Malmo ceased in 1987. As well as building ships the company built large industrial and agricultural machinery and maritime goods.this replica foghorn represents the design of a Swedish, Tyfon model 1910. It is an example of the type of safety equipment used on marine vessels to signal other vessels and signal to land. Replica foghorn; portable marine, plunger operation. It has a brass cylinder and adjustable brass horn. The plunger handle and base are wooden. Inscriptions are on the plaque on the horn and moulded into the air intake.

The navigational computer was a circular slide rule used for calculating height and air speed corrections when flying an aircraft. The front cover lifts to reveal a further calculator used to solve vector triangles and plot course alterations. The device was intended to be strapped to a pilot's leg. The instrument was made by White and Gillespie (Melbourne) Pty Ltd c 1940 for the RAAF and used during WW2.Black metal box with silver metal flap top cover affixed with rotating circular rule .
