The Global Positioning System (GPS) is the only fully functional Global Navigation Satellite System (GNSS). The GPS uses a constellation of at least 24 (32 by March 2008) Medium Earth Orbit satellites that transmit precise microwave signals, that enable GPS receivers to determine their location, speed, direction, and time. GPS was developed by the United States Department of Defense. Its official name is NAVSTAR-GPS. Although NAVSTAR-GPS is not an acronym[1], a few backronyms have been created for it[2]. The GPS satellite constellation is managed by the United States Air Force 50th Space Wing.

Similar satellite navigation systems include the Russian GLONASS (incomplete as of 2008), the upcoming European Galileo positioning system, the proposed COMPASS navigation system of China, and IRNSS of India.

      Its All About Location: A Location Technology Tutorial

      In the mid-1990s, mobile location services appeared to be one of the next natural steps in our move towards a truly unwired, permanently connected society. The ability to link a user's content and personalized services with his geographic location seemed like a killer application-an application with the potential to bring new waves of revenue and customer loyalty to an industry already riding high. Backed by venture capital and fueled in...

Mark Twain quote for the day:

You see I don't care much about acquaintances. When I can come & go, & not be misunderstood, & can be at liberty & unweighted, uncriticized, unsuspected, as part of the very household, as at your house & Mrs. Fairbanks's my "friendship" (as we term it) really comes nearer being worship than anything else I can liken it to but to be a ceremonious visitor; a person of set hours & seasons; a foreigner in the household, without naturalization papers; an alien from whose ears the language of the fireside is withheld; an effigy to poke politenesses at & offend with affabilities that are hollow, invitations that are not meant, & complementary lies that are as thin & perishable as the air they are made of- this is Acquaintanceship, & very little of it goes a great way with me.
- Letter to Olivia Langdon, 3/6/1869
