How to clean the car navigation memory?
Car navigation is an instrument that can help users accurately locate the current position, calculate the journey according to the established destination, and guide users to the destination through map display and voice prompts.
At the same time, the corresponding detection sensor is installed in the car, and the anti-theft alarm information can be sent to the third party by using the GSM network communication function of the car GPS positioning, or the alarm phone and short message can be directly sent to the car owner's mobile phone to complete the car GPS anti-theft alarm. It can be seen that the GSM network part of vehicle GPS positioning is actually a smart phone, which can communicate with third parties, and can also send information such as vehicle robbery, driver robbery and kidnapping to third parties. So vehicle GPS positioning is positioning, anti-theft and anti-robbery. Similar to car GPS terminals, there are also positioning mobile phones and personal locators. Because GPS satellite positioning needs third-party positioning service, it needs to pay different monthly/annual service fees. At present, all GPS positioning terminals have no navigation function. Because hardware and software need to be added, the cost is increased. The car GPS advertisement we saw on TV is completely different from the car GPS above. It is a GPS navigation product. When navigation is needed, locate first, which is the starting point of navigation. This is different from real GPS positioning. It can't transmit the positioning information to the third party and the holder, because the navigator lacks the function of the mobile phone. For example, if you put the navigator in the car, your friend borrowed the car, and the navigator can't send you a message, then you can't find the location of the car. So the navigator can't locate it. You said I bought a navigation phone, right? Think about it. You left your navigation phone in the car, and now the car has been stolen. Will that mobile phone call you or send a text message to a third party? It needs people to operate it. Therefore, the current navigation terminals have no positioning function. The navigation terminal can navigate the route, so that you don't get lost in a strange place, draw the route to your destination, tell you the current location, surrounding facilities and so on.
Cause analysis of insufficient vehicle navigation memory;
1, the built-in memory capacity of GPS is generally 64MB, and the personal portable navigator is 128, which is relatively rare; WINCE system usually takes up about 30 MB as system-specific, that is, the operating system platform, and the program we run is just a CE program in WINCE platform. This makes it difficult to run GPS navigator software. The CPU and memory in general navigator need to cooperate with each other to run perfectly.
2. The running navigation software mainly occupies memory when clicking the navigator, which is related to the skin interface of the navigation software. You can try Khalid's C version and T version to run. Because of the good skin interface, the C version is a little slower than 1-2 seconds, and the T version is faster. Similarly, Daotong 1.7 and Daotong 2.0 also have such problems. So, if you feel that the speed does not match the speed of the vehicle during use. Then you have to choose the right amount of navigator software.
3. click? Navigation? Individual riders click too fast, sometimes leading to the same navigation software running twice at the same time, which will lead to the prompt of insufficient memory space.
Thoughts and tools of clearing memory in vehicle navigation;
What if the running is displayed on it? Insufficient memory problem? Whether it is a car navigation system or a portable GPS navigation system, please be sure to check whether it is caused by the above reasons. If not, please use the following memory cleaning tools to clean up the memory. For details, please load a machine into multiple diagrams, and then set the execution path.
Related development of vehicle navigation;
The operation of the car navigator mainly depends on the Global Positioning System (GPS). GPS consists of three parts: space satellite, ground monitoring and user receiving. In space, there are 24 satellites in a distribution network, distributed on 6 satellites with an inclination angle of 55? In the quasi-synchronous orbit of the earth, there are four satellites in each orbit. GPS satellites orbit the earth once every 12 hour, so that signals from 7 ~ 9 satellites can be received at any place on the earth at the same time. There are 1 master control stations and 5 monitoring stations on the ground, which are responsible for satellite monitoring, telemetry, tracking and control. They are responsible for observing each satellite and providing observation data to the main control station. After receiving the data, the main control station calculates the precise position of each satellite at each moment, and transmits it to the satellite through three injection stations, and then the satellite transmits these data to the receiving terminal equipment of the user through radio waves. Note: The system was originally developed jointly by the US Army, Navy and Air Force in 1970s. Its main purpose is to provide real-time, all-weather and global navigation services for land, sea and air for some military purposes such as intelligence gathering, nuclear explosion monitoring and emergency communication, which is an important deployment of the US strategy of dominating the world. After more than 20 years of research and experiments, the GPS system cost 30 billion dollars. It was not until 65438+1March 1994 that 24 GPS satellite constellations with global coverage of 98% were officially laid out. At present, the application of GPS system is not limited to the military field, but has developed into various fields such as automobile navigation, atmospheric observation, geographical survey, ocean rescue, manned spacecraft protection detection and so on.
