Within 20 years we will no longer depend on GPS for navigation, at least not as the primary, or sole means of navigation toward which we are currently moving. We already have some pretty good solid state gyros and inertial systems. I'd bet that we are going to reach a point where we will be able to have small, compact, and inexpensive systems that will be independent of outside sources except for possibly "correction, or reference points". those points could be GPS and/or widely spaced ground stations. According to my "SR-71 POH" it used and INS with star mapping to correct it. They have improved tremendously in the optics and microcontroller since that system was devised so I would think you could use something like that today without to much trouble. John Sure, if you can fly high enough so the stars are visible during daylight. Otherwise, this will only work at night and if there isn't too much cloud cover. -- Kevin Horton RV-8 (finishing kit) Ottawa, Canada http://go.phpwebhosting.com/~khorton/rv8/ e-mail: khorton02(_at_)rogers(_dot_)com |
