In terms of positioning navigation needs, the number of commonly used car and mobile phone users is quite large, for people who do not know much about car navigation and mobile phone navigation, you can deeply understand the differences and differences between the two from the aspects of convenience, performance and installation.
One: portability
There is no doubt that mobile phones are superior, can be put into the pocket anytime and anywhere, and have a great advantage in portability.
Car navigation is the need to be bound to the vehicle, the current market sales of positioning module size is mostly in 97 * 50 * 32mm or so, than the mobile phone or larger. In addition, some mobile phone navigation functions add motion sensors, which can count the number of walking steps in the environment of sidewalks, overpasses, underpasses, squares, etc., guide the route, and greatly improve the practicality of mobile phone navigation.
Due to the portability of mobile phones, car navigation really has no advantage in portability.
Vehicle positioning
Two: installation mode
There is almost no difference between the two in the installation, when it comes to the hands of the end user, it is a finished product, except for a few special needs users who need to modify it themselves, the installation process has been realized by the manufacturer. The car positioning navigation module has the corresponding supporting bracket to choose from, and the mobile phone navigation does not, and the purchase can be widely selected.

Three: Navigation performance
In terms of performance, there are system hardware and satellite reception capacity to decide, hardware on both have a high, high and low points, according to the consumption capacity to buy the corresponding price can be, the performance difference is not big, can only be said to have their own advantages.
In terms of satellite signal reception capacity, due to the size of the installation space of the two, the mobile phone is limited by the size of the body, the antenna performance will be lower than the vehicle positioning module, and the general vehicle positioning module is stronger than the mobile phone in the ability to receive satellite signals, and the individual cost-effective mobile phones may not lag behind the navigator, or even better.
Positioning module navigation module of pure hardware cold start, pure hardware hot start, pure hardware recapture time, of which the cold start time is longer, within 30 seconds, hot start and capture signal time are within one second, this point of mobile phone navigation function is mostly compressed in the chip, the parameter concept is relatively vague, the performance is not as high as the requirements that can be used for vehicle positioning modules.
For the future planning of intelligent transportation, the acquisition of parameters such as running trajectory, mileage, speed, and stop location, monitoring alarms, and electronic fence functions, the positioning module needs to play more roles, which cannot be achieved by mobile phone navigation.

Four: Operation
There is almost no difference in the operation of smart phones and common navigators, and the keyboard is not much different in terms of efficiency of control with touch screen zoom.
Five: Visualization
At this point, the relationship with the specific mobile phone screen, navigation flat size, usually the mobile phone screen is smaller than the display screen equipped with the vehicle positioning module, and some positioning modules with DTU modules, you can view the running trajectory and other information through the mobile phone and computer interface, and the visual area is larger than the large-screen mobile phone.
In the specific use environment, driving or walking navigation, both are voice-supported, and there is little difference in convenience.
Locate the navigation interface
Six: Navigation ability
Navigation function is the top priority, usually the user can not directly face the hardware, and the software contact is more, the software platform may be somewhat different in the specific operation, the necessary functions are not much different.
In fact, for the positioning module that needs to receive satellite signals, the navigation performance and the number of satellite signals received have a certain degree, horizontal positioning accuracy, height positioning accuracy, speed positioning accuracy represent the positioning accuracy of the positioning module, generally around 3M, 0.1M/S.
Seven: Price
Mobile phone navigation chip price is relatively vague, most of the mobile phone manufacturers batch order, users can not know, positioning module due to the wide range of applications, ship positioning, engineering surveying, agricultural machinery automatic driving and other industrial needs, there are clear prices on the market, most of them are more than 100 yuan.
Whether it is vehicle navigation or mobile phone navigation, it is a reaction to the application of Internet of Things technology, which jointly improves our quality of life and is the result of technological development.
