Global Positioning Systems (GPS)

The U.S. military was the first to develop and use GPS technology in the 1970s for navigation and positioning purposes. It was later made available for civilian use in the 1980s.

It was established in 1973 to overcome the limitations of previous navigation systems.

I am just going through some of the physics myself, but if i understand it properly, the higher the frequency, the shorter the wavelength the less likely it is that the wave will bounce around keeping signals accurate.

With the increased accuracy comes the use of gps in navigation for weapons and other sorts of things they don't want impacting in the wrong place. With 4 satelites or 3 satelites and a ground station at that frequency they should be able to pinpoint something down to a few millimeters.

go to the back of the unit and look for a red wire, snip it, then put a male plug on one side and a female plug on the other, and plug it in and out. The other way is to put a toggle switch in our vehicle and cut the red wire, plug use to female plugs and plug them into each side of the switch, when you want to turn it off, turn the switch off, then when you want it on, turn it back on. Though many commercial 'truck' or 'company' GPS unites store your data with a time - this is to protect the driver and company and lower the insurance. So if someone accuses you of a crime, your GPS data will show without question that you are on the other side of town -- so court cases are easily dismissed.

Another way is to simply unplug the antenna -- some antennas plug in, and these can have the plug expanded so that they fall out easily and are far more easily explained than cut wires or hidden switches. thought again, many commercial units have time AND data stamps on them and if it falls out every day or every Monday and Wednesday at 3:30 and says off until $:20 - questions might arise.

another solution is to just twist the connections just about an half an inch back from the plug to help create an internal short. Or usE Emory paper on the cord, and then shine up the area around where it enters the body of the vehicle - and there should not be a rubber or tight steel grommet there -- and it will look like it has worn itself out -- this COULD cause 'intermittent' failure - but you best be sure that the problems happen on an off all day long -- and be ready to explain why you never noticed that you had no reception on your GPS when you checked it for any reason - including bordom.

of course the easiest way is to just turn it off - unless it is meant to keep track of you ans where that vehicle is going -- some trucks and buses have RPM trackers which track your gear vs your speed vs your RPM to see if you are 1) speeding 2) OVER or UNDER revving your diesel engine before you shift, and if you re in the right gear for your load -- all of which gets very expensive when it comes to preventive maintenance -- a 250,000 transmission jog should not have to be done at 120,000 miles unless there were faulty materials used -- and the log is admissible evidence court -- so if a mechanic shows that he installed top of he line bearings in your White or Kenworth and they all begging to fail at 120,000 miles and generally last well over 300,000 miles, then a secondary suit might be started against the mechanic, and HIS recoreds shold show a pattern of poor rebuilds.

You can turn it on -- take a large syrenge from a feed store, and inject water into the unit through the vent holes while it is moving, and short out the intenal parts -- but there is always explaining to do.

A very wise attorney once told me - when you question the legality of an action, you have probably already crossed the line of morality.

MY Question to yo is WHY do you want to to disable it? If you are doing what you should, then there is no reason to disable it unless the light interferes with your ability to drive at which point you need to go to to a real electrical shop that sells the unit and have a dimmer to off switch installed. and that will dim the screen, but not turn the device off.

YF International (China) GPS systems contain NAVTEQ maps. If you go to the NAVTEQ website to buy map updates, strangely YF International is not on the list of brands for which they offer map updates. Your best bet would be to visit NAVTEQ website (http://allthingsnav.navigation.com/) and contact customer support with your query.

GPS technology has revolutionized navigation by providing precise location information globally, enabling efficient route planning and real-time tracking. It has improved accuracy and reliability compared to traditional methods like maps and compasses, making it essential for various industries such as aviation, shipping, and transportation. GPS has also influenced the development of location-based services, like ride-sharing apps and geotagging features on social media.

By tracking your activities for one week, you can gain insights into how you spend your time, identify patterns or habits, and determine where you may need to make adjustments to be more productive or efficient. Tracking activities can help you prioritize tasks, set goals, and focus on what truly matters to you.

The three segments of GPS are the space segment, which consists of the satellites orbiting Earth; the control segment, which includes the ground stations that monitor and maintain the satellites; and the user segment, which comprises the devices and receivers that utilize GPS signals for navigation and positioning.

That depends on the satellite. Many use cameras of various types, such as radio imaging, infrared, or visible spectrum. Others are used to measure pressure waves traveling through space. They can be designed to measure just about anything.

Tracking your spending habits helps you understand where your money is going, allowing you to make informed decisions on where to cut back or save. It also helps you stay within budget, avoid overspending, and reach financial goals more effectively.

Got a disk read error when I selected a program destination from our list. Tried a disk cleaner no luck. Checked disk for defect none found. Put disk back in same error. I clean with disk with isopropyl rubbing alcohol. DO not rub it on the disk, pat the disk with a very wet lint free towel or paper towel till the disk is wet. I let it soak for a few minutes. Very careful pat it with another paper towel till dry. I let it sit for 1 hour to insure it was dry. I put it back in trouble and error message gone been a month. Hope this help.

The cost of a GPS for your car can vary depending on the brand, model, and features. Basic GPS units can range from $50 to $200, while more advanced systems with additional features like live traffic updates and voice control can cost $200 to $500 or more.

An ergonomic chair with armrests that are adjustable in height and width allows for more natural positioning of your arms and hands. This can help reduce strain and discomfort on your shoulders, arms, and wrists while working at a desk.

The GPS satellites are not in geo-stationary orbit, but instead orbit twice every time the Earth rotates once. This means that for any observer the satellites appear to orbit once overhead each day. Such an arrangement gives better coverage. It is also clever in the sense that the motion of any GPS satellite will repeat itself each day.

The GPS constellation of 24 satellites are arranged in six different orbital planes, each inclined 55 degrees to the equator. To obtain exactly two orbits per day, the satellites are placed at an altitude of 20,200km!!!

1. It will catch a flame from entering the Earth's atmosphere. 2. It could explode causing pieces to fly eveywhere. 3. It can enter the atmosphere normally, and land in a very dangerous condition.

There are about 4 that go for one and the four share many. The four gives you an exact location. I am not sure how far away however

To use lane assist on a Garmin nuvi 1300, simply follow these steps:

1. When approaching a highway interchange or exit, the lane assist feature will display the available lanes and guide you to the correct one.
2. Pay attention to the lane guidance arrows on the screen and follow the directions to stay in the correct lane.
3. Lane assist will help you navigate complex intersections with ease by providing visual guidance on the device's display.
