While data sovereignty may require that records about a nation's citizens or residents follow its personal or financial data processing laws, data localization goes a step further in requiring that initial collection, processing, and storage first occur within the national boundaries. In some cases, data about a nation's citizens or residents ...
ISO/IEC 24730-2:2012 Information technology — Real time locating systems (RTLS) — Part 2: Direct Sequence Spread Spectrum (DSSS) 2,4 GHz air interface protocol; ISO/IEC 24730-5:2010 Information technology — Real-time locating systems (RTLS) — Part 5: Chirp spread spectrum (CSS) at 2,4 GHz air interface
Geopositioning uses various visual and electronic methods including position lines and position circles, celestial navigation, radio navigation, radio and WiFi positioning systems, and the use of satellite navigation systems. The calculation requires measurements or observations of distances or angles to reference points whose positions are known.
2005 DARPA Grand Challenge winner Stanley performed SLAM as part of its autonomous driving system. A map generated by a SLAM Robot. Simultaneous localization and mapping (SLAM) is the computational problem of constructing or updating a map of an unknown environment while simultaneously keeping track of an agent's location within it.
A visual positioning system can determine the location of a camera-enabled mobile device by decoding location coordinates from visual markers. In such a system, markers are placed at specific locations throughout a venue, each marker encoding that location's coordinates: latitude, longitude and height off the floor.
EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement, originated by a member of the European Petroleum Survey Group (EPSG) in 1985.
Modern development systems and operating systems include sophisticated libraries for international support of these types, see also Standard locale data above. Many localization issues (e.g. writing direction, text sorting) require more profound changes in the software than text translation.
There are many biases within the measurement system that, if not accounted for properly, will manifest themselves as time delays or frequency offsets. For example, while a satellite translation frequency is known to within a few kHz, accurate geolocation requires frequency measurement accuracies of single mHz.
