Historical information

This is a set of two 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. Refer to item 6226.4P for more photographs of WO2 Graham Ragless demonstrating the TI4100.
