  • Submarine Navigator, U.S. Navy, Ret. | Time and Navigation
    The SINS Ship s Inertial Navigation System was in the Navigation Center of the ship as was all the navigation equipment The SINS maintained the ship s position at all times through a system of gyroscopes accelerometers and velocity meters All this equipment was controlled through the Navigation Data Computer a big computer in the Nav Center This was one of the first large scale computer systems in the Navy When these ships went to sea in the 60s it was the first time digital equipment was used in a weapons systems It was a breakthrough like the MARDAN and the Navigation Data Computer We had six or seven computers the MARDAN that ran the SINS a computer that ran the Transit system and a computer that ran the LORAN system and over the top of all of these we had the NAVDAC Navigation Data Computer SINS position was plotted every half hour on graph paper These positions were compared to fixes taken by LORAN C Transit bottom contour or celestial navigation fixes If the SINS position exceeded the required accuracy based on external fixes the SINS position was corrected through the computer system What is Bottom Contour Navigation Bottom Contour Navigation used specific bottom contour charts and sonar to fix a ship s position These were very highly measured areas and we d run across them several times and fix position with soundings For the soundings we could vary the power of the sonar we were putting sound in the water to avoid detection Why did you use LORAN C The mission of the ship was to remain undetected so that no one knew where the boat was Any activity at periscope depth with mast exposed could result in detection either by friendly or unfriendly forces So the captain wouldn t let me go up as often as I wanted and made me rely on LORAN C LORAN C was continuously copied on a floating wire antenna while remaining deep because of its frequency The antenna floated just below the surface trailed behind the ship out to I think it was 1500 feet LORAN C was less accurate than Transit How did you use a satellite system like Transit if you were underwater For Transit fixes we had to go to periscope depth and raise a special antenna In those days we didn t get a Transit fix very often maybe once every 3 days because we had continuous LORAN coverage We were at periscope depth for about 15 minutes and we d track the satellite from time of rise to the time it set Why did it take so long compared to GPS It was the Doppler system with 2 frequencies and we had to listen for a period of time to both frequencies How did you use celestial navigation We used a specialized periscope with a very accurate built in sextant to compute the ship s position and heading using normal celestial sighting procedures The periscope system

  • Corn and Soybean Farmer | Time and Navigation
    it s much more difficult to follow a planter mark accurately How do you use navigational tools All of our tractors and the combine and sprayer are capable of hands off steering Using hands off steering letting GPS guide the vehicle makes us more efficient and sometimes it allows us to operate when we simply couldn t otherwise What kinds of navigational challenges do you face The challenges include darkness dust the width of the implement the need for precision on wide equipment and being able to return to the same place in the field for any number of reasons How has navigational technology changed your life It makes us more efficient We can work longer days with less fatigue We manage better because we can better answer some of the why questions we see every year in farming Field to Table Agriculture and transportation are among the fields transformed by global navigation Satellite navigation helps farmers maintain high crop yields reduce costs and lessen environmental impact Goods from farms and factories can be guided to their destinations by ship truck railroad or aircraft Vehicle tracking provides near real time data on shipments all the way from farm or factory to individual homes Roy Bardole in His Tractor Farmer Roy Bardole seated at the controls of his combine in a cornfield on farm in Iowa A GPS guidance system display is mounted at the top center on right side of cab Credit National Air and Space Museum Smithsonian Institution Roy Bardole in His Office Farmer Roy Bardole seated in his office views an agricultural GPS image on his computer monitor while field maps are laid out on his desk Credit National Air and Space Museum Smithsonian Institution A Tractor Performing Precision Agriculture A combine driven by farmer Tim Bardole harvesting

    safety Before they could get out the structure collapsed killing the lost team and four of their would be rescuers Why do you need better positioning navigation and timing technology When firefighters enter a burning structure especially large complex commercial buildings they can quickly lose visibility and their ability to maintain orientation And traditional GPS doesn t work inside buildings How are firefighters normally tracked indoors The fire chief keeps track of the crew s positions by following radio calls and drawing a sketch on an accountability board but it s all too easy for critical information to be missed or misinterpreted How is this technology changing your life We are getting close to a reliable and affordable solution that uses technologies such as inertial navigation and others to provide real time positional data of our firefighters Knowing where your teams are at all times can be critical when things go wrong The Challenge of Indoor Navigation Emergency personnel cannot receive GPS signals indoors New navigation systems combining radio signals with inertial navigation are now in testing Cell phone companies retailers and other organizations are also exploring the possibilities of indoor navigation technology Worcester Polytechnic Institute Deputy Chief of the Worchester Fire Department John F Sullivan When firefighters enter a burning structure especially large complex commercial buildings they can quickly lose visibility and their ability to maintain orientation And traditional GPS doesn t work inside buildings Credit Worcester Polytechnic Institute WPI test When firefighters enter a burning structure especially large complex commercial buildings they can quickly lose visibility and their ability to maintain orientation And traditional GPS doesn t work inside buildings Credit Worcester Polytechnic Institute WPI A Future Concept for a Firefighter Locator System This graphic shows how personal radiometric and inertial navigation devices could allow incident commanders to
