Dilution of precision is one of the most important parameter to consider for satellite navigation. With the existent full operational US operated GPS system the position can be calculated anywhere in the world. The upcoming European Galileo system is also a strong contender for the efficient calculation of position determination. Comparing both the GPS and Galileo in terms of GDOP and PDOP and also...
Space-based navigation was not only the first method of long-distance navigation but is the most advanced today. It proved superior to any other guidance system as it is all weather, immune to precipitation static and propagates predictably through the atmosphere. GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), Galileo are the systems that are now harbinger of navigation...
Global navigation satellite systems (GNSS) is the collective term for those navigation systems that provide the user with a three-dimensional positioning solution by passive ranging using radio signals transmitted by satellites. The most well known is the Navigation by Satellite Ranging and Timing (NAVSTAR) Global Positioning System (GPS). It is the most advanced but still not free from erroneous...
