This is a precis produced by the Royal Australian Survey Corps School of Military Survey in 1964. This is a very technical precis that describes the corrections that need to be applied to First Order Astronomical Theodolite Observations. First Order Astronomical positioning is the highest order and the most accurate determination of position using the stars and for that reason small allowances and corrections are needed to maintain/ improve relative accuracy.A 26 x page foolscap sized paper Precis, stapled and two hole punched. The precis does not have a protective cover and pages are discoloured. The precis contains typed text, tables and diagrams.royal australian survey corps, rasvy, fortuna, army survey regiment, army svy regt, asr, astronomy

This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory and North Queensland in 1959 – 1960. The surveyors were employed in the establishment of mapping and geodetic control. In this era surveyors used theodolites to observe horizontal and vertical angles and tellurometers to measure base line distances between survey stations. Laplace survey observations seen in Photo .1P was a series of precise observations carried out at geodetic survey stations to determine astronomic latitudes, longitudes and azimuths to achieve maximum precision in the survey network. Laplace observations were necessary in a geodetic network at every 6th survey station, however the National Mapping Council specified at this time the spacing would be ideally between 4-6 survey stations. The cairn shown in photo .4P was built by RASvy as a landmark over a trigonometric survey station. It was dismantled in 1960 to enable re-occupation and survey observations. It was not restored to the condition shown in the photo.This is a set of 10 photographs of surveyors and support staff in the field undertaking duties in the Northern Territory (NT) and Queensland (QLD) in 1959 – 1960. The photographs were printed on photographic paper and are part of the Army Survey Regiment’s Collection. The photographs were scanned at 300 dpi. .1) - Photo, colour, 1959.

329 pages, illustrated, navy blue linen cover and red paper dust jacket.non-fictionThis volume of the Admiralty Manual of Navigation describes off-shore navigation - the safe conduct of a ship across the open sea where, in general, hearings of objects on land cannot be obtained except by means of radio waves (i.e. using radio fixing aids). The first chapters are mainly concerned with distances, courses, tracks and charts; then various methods of obtaining position lines and positions from astronomical observations are explained, including a rapid. method in the last chapter. The volume also contains an outline of meteorrology and weather forecasting.howard timbury, first fleet fellowship victoria, interest group, navigation, education
