What is meant by navigation?
Navigation centers around the most common way of checking and
controlling the development of a specialty or vehicle starting with one spot
then onto the next, the techniques used to realize where somebody is and how
to go to somewhere else in new place.
It is additionally the term of workmanship utilized for the specific
information utilized by guides to perform route undertakings. All
navigational strategies include finding the guide's position contrasted with
known areas or examples.
Navigation makes a wider sense that refers to any type skill or study that
involves locating the location, direction. The navigation is executed or
work with the help satellite which is termed as Global Navigation Satellite
Systems (GNSS)
How is Location Determine of any place?
The Location can be assigned involving a particular matching of scope
and longitude in a Cartesian direction framework (for instance, a circular
direction framework or an ellipsoid-based framework like the World Geodetic
System) or comparable strategies.
The Classification of Navigation System
GNSS-1 is the original
framework and is the blend of existing satellite route frameworks
(GPS and GLONASS), with Satellite Based Augmentation Systems
(SBAS) or Ground Based Augmentation Systems (GBAS).In the
United States, the satellite based part is the Wide Area Augmentation System
(WAAS), in Europe it is the European Geostationary Navigation Overlay
Service (EGNOS), and in Japan it is the Multi-Functional Satellite
Augmentation System (MSAS). Ground based expansion is given by
frameworks like the Local Area Augmentation System (LAAS).
GNSS-2 is the second era of
frameworks that freely gives a full regular citizen satellite route
framework, exemplified by the European Galileo situating framework. These
frameworks will give the precision and trustworthiness observing important
for common route; including airplane. At first, this framework comprised of
just Upper L Band recurrence sets (L1 for GPS, E1 for Galileo, G1 for
GLONASS). Lately, GNSS frameworks have started enacting Lower L-Band
recurrence sets (L2 and L5 for GPS, E5a and E5b for Galileo, G3 for GLONASS)
for regular citizen use; they highlight higher total precision and less
issues with signal reflection.
By their roles in the navigation system they can be classified as :-
- Core Satellite navigation systems, currently GPS (United States), GLONASS (Russian Federation), Beidou (China) and Galileo (European Union).
- Global Satellite Based Augmentation Systems (SBAS) such as OmniSTAR and StarFire.
- Regional SBAS including WAAS (US), EGNOS (EU), MSAS (Japan), GAGAN (India), SDCM (Russia)
- Regional Satellite Navigation Systems such as India's NAVIC, and Japan's QZSS.
- Continental scale Ground Based Augmentation Systems (GBAS) for example the Australian GRAS and the joint US Coast Guard, Canadian Coast Guard, US Army Corps of Engineers and US Department of Transportation National Differential GPS (DGPS) service.
- Regional scale GBAS such as CORS networks.
- Local GBAS typified by a single GPS reference station operating Real Time Kinematic (RTK) corrections.
