<strong><b><font face="Times New Roman">Feb. 14, 1989: GPS Enters Orbit</font></b></strong><b><span

1989: The first of 24 satellites that will comprise the global positioning
system is put into orbit. <br>
<br>
GPS revolutionized navigation, both at sea and on land, by providing position
reports with unprecedented, pinpoint accuracy. Each satellite is placed in a
specific orbit at a specific altitude to ensure that four or five satellites
are always within range from any point on the planet. A GPS receiver picks up
signals from the satellites and trilaterates the data to fix the position. <br>
<br>
This satellite system is so valuable -- besides navigation, GPS has
applications in map-making, land surveying and the accurate telling of time --
that even though it was developed and is maintained by the U.S. Department of
Defense, it is made available without charge to anyone, anywhere on Earth. <br>
<br>
Although GPS has eliminated the need for determining a ship's position by
shooting the sun or stars, no sailor worthy of the name would put to sea, even
now, without the ability to use a sextant. Electronic navigation devices fail
and even GPS isn't immune to the odd glitch, and the open ocean is a lonely
place to be if you don't know where you are. <br>
