This is a set of four photographs of WO2 Graham Ragless from the Royal Australian Survey Corps demonstrating the operation of Global Positioning System equipment in c1988. The photos were probably taken at the School of Military Survey (SMS), Bonegilla, VIC. Texas Instruments TI4100 portable Global Positioning System (GPS) geodetic receivers were introduced from 1986–1988. The GPS receivers and Ferranti FILS3 helicopter and vehicle mounted Inertial Positioning System (IPS) replaced the TRANSIT satellite receivers. The equipment was deployed to establish the baseline for a GPS controlled air camera and photogrammetric system to significantly reduce the requirement for ground survey to accurately control air photography for topographic mapping. Personnel from the four field survey squadrons at this time were trained at the SMS to operate the TI4100 receivers. Field survey operations using GPS and IPS equipment followed in the late 1980s. This technology is described in more detail in the RA Svy booklet titled An Introduction to Topographic Mapping. See record ID - 6010. WO2 Graham Ragless progressed to the rank of WO1 and was appointed as RSM of the Army Survey Regiment from 1990 to 1992.

This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.

This is a superbly crafted cartographic mapping instrument. It is housed in its own high-quality purpose-built oak box. Made in the Netherlands from 1950 onwards. This instrument is from c 1956. it is a very high-quality military grade stereoscope that was generally used by photographic interpreters such as intelligence analysts but was equally useful for mapping activities. The stereoscope was used to examine 3D aerial photographic images. This instrument has a particularly useful capability to scan over the 3D stereo model using X and Y movement knobs, rather than having to physically move the aerial photographs. In the public and private sector it was also useful for photogrammetric interpretation for Forestry and Agricultural purposes.

The Heliograph MkV is a fascinating piece of historical surveying and communications equipment. It was primarily used for visual signaling by reflecting sunlight with a mirror to send coded messages over long distances. This method was primarily useful in remote areas where other forms of communication were not available. The MkV model, specifically, was widely used by the British Army and other military forces from around 1906 until the mid 1960s. It remained in use with the Australian Army Survey Corps until the mid 1980s. The device typically included a 5 - inch mirror and was often mounted on a tripod for stability. Initially the instrument was used to communicate between survey stations using Morse code to coordinate their activities. Later when better forms of communication were available they were used for precise angle alignment where the sunlight reflection from the mirror was targeted between the survey stations to give very accurate results. The MkV was relatively light weight and portable, making it ideal for use in the field. It could be setup and adjusted quickly. The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. This instrument was used as a training aid to help teach surveyors at the Royal Australian Survey Corps School of Military Survey.

This is a set of 1photographs of surveyors in the field measuring distances using chains, taking observations using theodolites and operating electric distance measurement equipment. They were probably employed in establishing mapping and geodetic control operations or the surveyors may have been in training. The photos were most likely taken in the 1950s and 1960s. Photos .1P to .6P feature personnel setting up geodetic survey chaining equipment to measure distances. The surveyor in Photo .5P is LTCOL Howard Angus Johnson MBE who served from 1936 to 1954. The RA Svy surveyor in photos .7P to .12P were using a theodolite to take angular measurements. They were usually supported by an observer who recording their readings on a booking form. The surveyor in Photo .10P and .11P is LTCOL Jorge Gruszka, who served from 1955 to 1985. He was CO of the Army Survey Regiment from 1982 to 1985. The surveyor in photo .13P is cutting an identification blaze on a tree using a hammer and chisel. The tellurometer in Photos .14P to .16P was a MRA1 microwave Electronic Distance Measuring instrument (EDM) introduced in 1958. It and later models were man-portable systems that improved geodetic survey efficiencies for rapid network extension and densification replacing triangulation with EDM and theodolite traverse sometimes using Bilby Towers to extend line lengths. The surveyor with the slouch hat is Colonel James ‘Jim’ Leslie Stedman, who served from 1941 to 1978. He was Director of Military Survey from 1975 to 1978 and was appointed as Colonel Commandant (honorary appointment, Retd) of the Royal Australian Survey Corps from 1978 to 1983.

Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. The British Army Mark V version uses a flat round mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adjusted the aiming rod so its cross wires bisected the target, they then turned up the sighting vane, which covered the cross wires with a diagram of a cross, and aligned the mirror with the tangent and elevation screws, so the small shadow that was a reflection of the unsilvered spot hole was on the cross target. This indicated that the sunbeam was pointing at the target. If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the sighting rod was replaced by a second mirror, to capture the sunlight and direct it onto the main mirror to reflect it to the receiving station.. 1 Brish Army "Mance" Mk V A253 Heliograph has two 125mm diameter mirrors on a brass arm with targeting attachments.

A Plane Table consists of a smooth wooden table surface (with metal strengthening supports) mounted on a sturdy base. The base, a three-legged Tripod, is designed to support the table over a specific point on land. The connection between the tabletop and the adjustable Tripod legs permits the user to level the table precisely, using bubble levels in a horizontal plane regardless of the roughness of the terrain. The Plane Table is a surveying device used in surveying and mapping to provide a level surface on which to make drawings, charts or maps. An alidade, with or without a telescope located on the tabletop is used to sight features and draw angles to that feature. Using these lines to the same feature from different setup locations it is possible to locate that feature on the map. Plane Tabeling was widely used by the early members of the Australian Survey Corps and in both World Wars. It remains a simple and effective tool to teach the fundamentals of mapping and surveying. It was simple to use and was reasonably robust and portable. See also item 6489.2 for the Plane Table Alidade.A wooden Plane Table with alloy fittings to strengthen and support the table top. The table is fixed to a three-legged wooden Tripod with cast alloy fittings and metal pointed tips.royal australian survey corps, rasvy, fortuna, army survey regiment, army svy regt, asr, 4 fd svy sqn, school of military survey
