How does a car navigation system work?

A car navigation system works by using GPS (Global Positioning System) technology to determine the current location of the vehicle and then calculates the best route to a desired destination. The system uses satellite signals and mapping data to provide real-time directions, estimated travel time, and other useful information to the driver.

Can you leave your Garmin GPS in your car during the summer when it is hot?

According to the Garmin Manual:

Limited Storage: -4 - 140F (-20 - 60c)

Extended Storage: 32 - 77F (0-25c)

Operating Range: -4 - 131F ( -20 - 55c)

This begs the question as to what "limited" means; 1 day, 1 week, 1 month?

One could assume that during transport from the factory however, the shipping containers the Garmins were stored in would have been exposed to various extremes in temperature which may have exceeded the "Limited Storage" ranges.

Block diagram of microwave communication link?

A microwave communication link typically consists of a transmitter, a receiver, and an antenna at both ends. The transmitter converts the electrical signal into microwave signals, which are then transmitted through the antenna. The receiver at the other end captures these microwave signals through its antenna and converts them back into electrical signals for further processing. The link may also include devices such as amplifiers, filters, and antennas to enhance signal quality and transmission.

How does gps work?

GPS receivers integrate a radio and a navigation computer and can receive the faint, twenty-watt signals coming from the satellites. The computer uses these signals to calculate the distance between the satellites and the receiver. With this information, the computer can further calculate the position and velocity of the receiver.

The number of satellites visible to a receiver constantly varies between four and eleven according to time and location. Each satellite broadcasts a number of unique spread-spectrum codes, but only one, the Coarse Acquisition (C/A) code, is easily accessible for civilian use.

On the ground all GPS receivers have an almanac programmed into their computers that tells them where in the sky each satellite is, moment by moment.

Why don't launch geostationary satellite for GPS?

Because they can't provide worldwide coverage. To cover near-polar areas, inclined orbits are necessaries. Since the geostationary orbit must lay on the equatorial plane, it doesn't suit to fit GPS requirements.

What will cause a gps not to recognize a destination in a city?

:

When using a GPS unit to locate addresses and places in a very dynamic (fast changing) environment, you may find what you are led to is no longer there. The maps on your GPS device are not realtime or updated automatically, they are often released once per year, and your device could qualify for a free update, depending on several factors. The destination you are choosing may no longer be located at the same address, or the road it exists on wasn't present at the time the maps were published and put into the GPS device.

Visit a GPS web forum to discuss your options, or visit the GPS manufacturer's website to see what updates are possible.

Possible reasons include omission from the locations database, use of incorrect city or state, component failure in device, non-existence of location (as when a skyscraper eliminates whole block of apartment buildings) or exceeding distance limitations of the device or system.

Alternatives: Try addresses without a building number; enter only part of a landmark's name (like Battery instead of Battery Point in NYC); and ask someone for directions!

What are the disadvantages of GPS?

In order to calculate its current positions, the GPS device needs to receive a data signal from 4 different satellites. If it cannot get signals from 4 satellites then it won't be able to calculate an accurate position.
