Frederic G. Snider , R. Course Description. It is now routinely possible to know your location within about 10 meters 30 feet anywhere in the world with inexpensive, hand-held commercial GPS receivers. It is also possible to use GPS for surveying at sub-centimeter accuracy, for control and monitoring of construction equipment and agricultural machinery, guidance of autonomous robots, and aircraft, vehicle and marine navigation. This course provides an explanation of how the GPS system works, sources of errors, and methods used for improving the basic accuracy of the system, including Differential GPS. Finally, the course summarizes what you, the potential user, needs to understand in order to select the appropriate equipment for the intended use.
An increasing number of studies suggest that characteristics of context, or the attributes of the places within which we live, work and socialize, are associated with variations in health-related behaviours and outcomes. The challenge for health research is to ensure that these places are accurately represented spatially, and to identify those aspects of context that are related to variations in health and amenable to modification. This study focuses on the design of a wearable global positioning system GPS data logger for the purpose of objectively measuring the temporal and spatial features of human activities. Person-specific GPS data provides a useful source of information to operationalize the concept of place. We designed and tested a lightweight, wearable GPS receiver, capable of logging location information for up to 70 hours continuously before recharging. The device is accurate to within 7 m in typical urban environments and performs well across a range of static and dynamic conditions.

Airborne geophysics has long been used for regional studies of remote and inaccessible areas. Recent developments in precise positioning of aircraft with the Global Positioning System GPS have greatly expanded the range of previously intractable science problems which now can be addressed with airborne techniques i.

Кто тебе сказал про вирус. - Это единственное разумное объяснение, - сказала. - Джабба уверяет, что вирус - единственное, что могло привести к столь долгой работе ТРАНСТЕКСТА. - Подожди минутку! - махнул он рукой, словно прося ее остановиться. - Стратмор сказал, что у них все в порядке. - Он солгал. Бринкерхофф не знал, что на это ответить.
Что вы делаете. Беккер понял, что перегнул палку. Он нервно оглядел коридор. Его уже выставили сегодня из больницы, и он не хотел, чтобы это случилось еще. - Nimm deinen FuB weg! - прорычал немец.
