Car GPS Buying Guide

Here are some of the most important aspect that may influence your decision to buy the best GPS for your car:

Budgeting For Car GPS
Unless money is no object, it is a good idea to start off by setting a general price range. If you are looking to spend less than a hundred dollars, you are probably going to scrimp a little on the features and have to settle for a small screen. You can also look for a bargain on an old model, but make sure that you do not end up with outdated maps that are impossible to update or either costly.
Your budget will also inform your decision to go for an integrated GPS or a standalone device. Head units that include built-in GPS navigation are usually quite expensive, so you may want to drive away from them unless your existing head unit is begging for an upgrade. In such a case, there are some head units, which include integrated GPS navigation that can boast some pretty impressive features.

Core GPS Navigation Features
There are a handful of GPS features that you should look before buying a GPS for your car, but here we listed down the most important ones are:

Screen size and resolution – Though larger screens are more accessible to see at a glance, which is important since you do not have to take your eyes off the road too much. Here resolution is also important since low-resolution images can be tough to read at a distance.

Audible directions – Text-to-speech, or spoken direction is tremendously important from a safety perspective. Most of GPS unit offer this, but some are difficult to understand. And you absolutely want to be able to understand your GPS unit from a safety perspective first.

Type of receiver – This is not an exciting feature, but the overall quality of a GPS is highly depended on how well its receiver works. If a GPS unit has poor sensitivity, it would not accurately show the position of your vehicle on the road.

Automatic routing – Automatic routing will automatically recalculate your route if you deviate from it. This feature is extremely important since reality includes things like accidents and construction that you may need to drive around.

Other less important aspects that can come in handy include:

Traffic – Some of GPS units and apps are capable of displaying traffic data also, which can help you gets where you are going without getting stuck in traffic jams.

3D map view – This feature allows you to view a 3D map of the location, which can help you orientate yourself in different/unfamiliar place.

Lane assist – This feature shows some infographic every time you approach interchange or an exit on a freeway. This is tremendously useful when driving in an unfamiliar place/area since it can help you avoid dangerously late lane changes.

Points of interest – This feature is useful on road trips, and when driving in an unfamiliar place, since it can help you locate restaurants, gas stations, motels, parks, rest stops, and other local businesses and landmarks.

Voice input – Some GPS units and apps allow you to set your route, and make alterations, with your voice command. This is useful if you do not have a co-pilot and need to make changes to your route on the fly.

Map Availability
Before you buy a GPS unit for your car, you should also look into availability and timeliness of map updates.
This is important especially if you are buying a discounted unit that is a little long in the tooth. While it is possible to find some incredible deals by shopping for old stock and factory refurbished car GPS units, it is vital to make sure that you do not get stuck with old map data.
If the map updates are expensive — or the company is not putting out updates anymore — then it might be wise to take a pass.

How Does GPS Technology Work?

How GPS Technology Work? Every aspect will be discussed about a GPS technology, let’s start:

The (GPS) Global Positioning System is a technical marvel made possible by a group of satellites rotating in Earth’s orbit. It transmits precise signals, allowing GPS receivers to calculate and display accurate location, time information to the user and speed. GPS is owned by the U.S.

By capturing the signals from satellites, Global Positioning System receivers can use the mathematical principle of trilateration to pinpoint your current location. With the addition of computing power and data stored in memory such as points of interest, topographic information, road maps, and much more, GPS receivers can convert speed, location, and time information into a useful display format.

how gps technology workInvention and Evolution of GPS
GPS was created by the U.S Department of Defense (DOD) as a military application. This system has been active since the early 1980s and began to become useful to civilian people in the late 1990s with the advent of devices used by people that support it. Consumer Global Positioning System has since become a multi-billion dollar industry with a wide array of services, products, and internet-based utilities. As with most technology, its development is ongoing; while it is a true modern marvel, engineers recognize its limitations and continuously working to overcome them.

GPS Capabilities

  • In all weather conditions, GPS works accurately, around the clock, and all around the globe.
  • There are no subscription charges to use GPS signals.
  • GPS receivers generally work well within 15 meters, and newer models that use (WAAS) Wide Area Augmentation System signals are accurate within 3 meters.

GPS Limitations

  • GPS signals may be blocked by skyscrapers, dense forest, canyon walls, walls, bridges, and the like, making accurate GPS navigation difficult or impossible.
  • Likewise, GPS does not work well in indoor and underground spaces.
  • Radio interference, satellite maintenance, and solar storms can cause coverage gaps.

An International Effort
The United State.-owned And -operated GPS is the world’s most widely used space-based satellite navigation system, but Russian GLONASS satellite constellation also provides such global service. Some consumer GPS devices use both systems to increase the likelihood of capturing sufficient position data and improvement of accuracy.

GPS systems work in 5 simple steps.

  • GPS is based on the “Trilateration Principle.”
  • To trilateration, a GPS receiver measures the distance through the travel time of radio signals.
  • Along with distance, GPS can locate the exact position of the satellites in space.
  • GPS uses very accurate timing to measure the travel time.
  • Finally, this system can correct for any delays that signal experiences as it travels throughout the atmosphere.

Trilateration Principle
Trilateration Principle is used to find the exact location of something or someone. It compares a person’s exact location from three or more places to determine a person’s exact location. Let us say there is a GPS unit located 600 miles away from Minneapolis. This means that it must be some point on a circle with a 600-mile radius around Minneapolis. If it is also 450-miles away from Boise, the GPS unit must be located at one of the two points where these two circles intersect. If we add a third measurement, like 700-miles from Tucson, we find that the three circles intersect in Denver. The GPS unit is therefore located in Denver.

Interesting Facts About GPS
The working of GPS is a mystery to many of the people who use it regularly. These factoids might surprise you:

  • Civilian GPS uses one frequency, while the military uses two frequencies. This increases accuracy. Dual-frequency GPS devices are available to civilians, but their size and cost make them impractical.
  • The United State’s government is engaged in an ongoing, modernization program and multibillion-dollar improvement.
  • U.S. taxpayers fund the world’s GPS services, through the Department of Defense. The 2017 budget was about 900 million dollars.
  • An American joint military/civil body, the National Executive Committee for Space-Based Positioning, Timing, and Navigation oversees the GPS. The U.S. Air Force maintains and operates it.
  • As of 2017, 24 GPS satellites circle the Earth.
  • GPS is essential to devices, services, conveniences we take for granted every day, such as cell phones, computers, watches, weather forecasting, navigation, energy delivery, and emergency/disaster response.
  • GPS is crucial to national security. All new military equipment is GPS-equipped.
  • Industries from banking, aviation, construction, and shipping to financial markets, farming, and so many more rely on the accuracy of GPS.
  • GPS informs the world’s sea, air, and road transportation systems.

GPS has many real-world applications. It is used by farmers, pilots, delivery drivers, sailors, scientists, soldiers, and many other professionals. The applications for GPS, however, fall into five broad categories:

  • Mapping
  • Location
  • Tracking
  • Navigation
  • Timing
