Global Navigation Satellite Systems - From Stellar to Satellite Navigation

   The advent of satellites and the advances thereafter of satellite navigation from the early 1960s till now changed the face of our life on Earth; Google maps and GPS car navigation systems are just testimonial of the indispensability of its importance. And yet, men still look to the sky for help. In the past, it was stellar navigation that guided men in their journeys and voyages around the Globe. Radio navigation aids appeared in the late 1930s and matured in the 1940s. Early studies exploring the idea of navigation by satellites were carried out by the US Air and Naval Forces in the early 1960s. The Navy Navigation Satellite System (NNSS or Transit) based on measuring the Doppler frequency of the received radio signal was the first all-weather continuous global navigation satellite system to emerge. The DoD NAVSTAR Global Positioning System program was initiated almost a decade later, through the merger of US Naval and Air Force projects. The first experimental GPS satellite was launched in 1977, while the first GPS receivers were introduced during the 1980s; they were big, cumbersome and expensive, and used a single channel receiver which consecutively locked on to each visible satellite and performed the pseudo-range measurement. By the 1990s, the receivers were multi-channel, more compact and cheaper; thanks to the emergence of the microprocessor. This was the period when GPS started to migrate from aircraft and ships - large and expensive platforms - to become a ubiquitous navigation system in military and civilian applications.

FUGRO GNSS Training - OSD 412 Complete Set

   This publication provides the content of the official GNSS training developed and released by Fugro. The Starfix Suite had its beginnings about 1997 with its concepts as a highly modular set of Microsoft windows applications all talking together via Message Manager, and synchronized via the Time subsystem. Once the basic backbone and basic modules were in place, it became much faster to bring new applications online, for much of the functionality such as interfacing, displays, logging, time series plotting etc was already written and proven. Two navigation modules were written due to fundamentally differing requirements. Starfix Nav was written and supported by John Chance as a navigation engine sitting on top of their Gulf of Mexico database - this is what was required for their operations. In Perth Australia, the DOS based PCNav/PCBarge which were in wide use around the Fugro companies was replaced by Starfix Seis - basically a classic line running type application. Adherence to Starfix Suite Compliance - a set of rules etc on how Starfix Suite applications talk to each other - by the software developers also then determined how well all the other applications could be used by either Nav or Seis.

New Shipboard Technology and Training Provision for Seafarers

   Makers' updates and company circulars provide another source of information for seafarers concerning shipboard equipment and new technology. In this research eight percent of seafarers were not aware, at all. of any company circulars or makers' updates being circulated to sea-staff in their current/most recent company. In relation to the responses to tins question, seafarer nationality played a particularly significant role. Having encountered a problem with the operation of a piece of equipment the overwhelming majority of respondents would consult a manual. Additionally, around a half of all respondents would consult colleagues. Department, ship type, seafarer age and nationality, were all found to influence the responses offered to tins question. In relation to the main engine maneuvering system engineers were very confident about their knowledge and understanding with 83% self-rating their knowledge of this equipment as 'excellent'. Engineers were less confident about their knowledge of oily water separators however with only 40% claiming 'excellent' knowledge of tins equipment. Overall engineers were least confident about high voltage equipment and 37% of engineers self-rated their knowledge of this equipment as 'basic' or even 'zero'. Navigation officers were markedly more confident about their understanding of AIS and GPS than they were about their understanding of ARPA, GMDSS, and ECDIS. ECDIS was the equipment which officers were least confident about overall, with 9% self-rating their understanding of ECDIS as 'zero1 and a further 21% suggesting it was basic. Respondents were more confident about ARPA than they were about GMDSS with four percent self-rating their knowledge of ARPA as basic compared with 13% self-rating their knowledge of GMDSS as 'basic'. Although only a quarter of seafarers had an input into the identification of their training needs, almost half of respondents were expected to pay towards their training. Nationality, ship type, department, and age, all impacted upon the responses of seafarers to this question. In relation to compensation for lost leave almost half our respondents stated that it was not usual for them to be compensated for leave time lost as a result of required training in relation to new shipboard technology...
