The US government thus chose to remove the intentional deterioration in GPS accuracy for public use (Selective Availability). The &#8220;military&#8221; precision of GPS became usable by the general public, free of charge. Six years earlier, I had written my thesis on an aerospace application of this system, and at the time I fully understood the significance of this decision, which is now clear: GPS is used daily by everyone. And also the importance of having this lever, which I compare to John Harrison&#8217;s invention of portable watches for maritime use to calculate longitude precisely (there&#8217;s a great book by Dava Sobel), which was long jealously guarded as a military secret by the Royal Navy&#8230; Today, GPS is supported by several other similar or complementary satellite systems: GLONASS (Russia), Galileo (Europe), Beidou (China), QZSS (Japan), IRNSS (India).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Bill Clinton eliminated Selective Availability distortion in the GPS signal.
