 How fast is the high-speed rail car? How to measure speed with mobile phone


Baidu map speed measurement

This is an app that everyone is quite familiar with. Baidu map is one of the most popular map navigation apps in China. In fact, it has the function of speed measurement. Click the logo of Baidu maps main interface, and then find the footprints. The speed measurement function of Baidu map is hidden here.

Speed measurement function of Baidu map

GPS dashboard

After all, the main function of Baidu map is not speed measurement. If you are not the user of Baidu map, you just want to use GPS to measure the speed and dont want to install a Baidu map, then there are other small tools available - for example, this GPS dashboard which specializes in GPS speed measurement.

GPS dashboard app is from abroad, but it supports Chinese language, but some functions are not specially grounded, which will be mentioned below. The GPS dashboard app is also very simple to use. When it is turned on, it will automatically search for stars and give the current speed. Not only that, the GPS dashboard app can also record the curve of speed change, which is very practical.

GPS instrument panel speed measurement interface

In the app of GPS instrument panel, many recording functions can be realized. In addition to recording speed, travel and track can also be recorded. If you travel a lot and use the app to record the history track, it will be interesting in the future. However, it should be noted that the GPS dashboard app uses Google map as the track base map, which is inconvenient to use in China, but if it is only used to measure the speed, it is more than enough.

Record stroke

Compared with the map app, the GPS dashboard app also has the advantage of not correcting the speed. Some map navigation apps may underestimate the speed due to various reasons such as laws and regulations, which is the same as the reason that the automobile instrument specifies to display 0 u2264 indicated speed - actual speed u2264 actual speed / 10 + 4km / h. GPS tools such as GPS dashboard app have no such limitation, and the speed measurement will be more accurate.

GPSTest

The GPS dashboard is free, but there are advertisements. If you want a cleaner experience, GPST app may be worth considering.

Gpstest is an open-source GPS small application, the main role is to test the current mobile GPS and other navigation satellite connection status. However, it can also measure the current moving speed according to the relevant information. If it needs simple speed measurement, it can fully meet the needs.

Gpstest interface with speed information

The use of gpstest is also quite simple. After the app is opened, you can see the search for Stars of the mobile phone. Among them, the main interface will present longitude, latitude, height and other information, and the speed will be measured in real time. Gpstest provides different views, such as sky view and map view, but it cant record the speed. I hope it can add related functions in the future. Like the GPS dashboard app, gpstest is not limited by the speed correction laws and regulations. The speed measurement value is relatively reliable. You can try it. How about the summary? Can the above mobile speed measuring tools satisfy you? However, it should also be noted that GPS speed measurement has its limitations. For example, when taking the high-speed railway, caves and even cars will affect the reception of GPS signals, which may only be achieved by windows. However, if you want to measure the speed, these apps are worth a try. Visit: Alibaba cloud - up to 1888 yuan of universal voucher can be read immediately.
