How to use GPS to save yourself in the wild


In daily life, we will inevitably encounter some accidents and unexpected situations, especially with the rise of outdoor sports and adventures, more and more young people are keen to explore some original undeveloped places, and this is also Increased accidents and dangers. If there is a disaster in the wild or in the night, we need to know the exact location of the phone in addition to the call, then how to get it?
GPS Tracker


        Today's smartphones are basically equipped with GPS chips. They can use GPS satellites for positioning. Even if the phone has no signal, it can be used normally. It can quickly find the nearest city, country and other areas in the wild, and also allows search and rescue personnel to know where we are by mobile phone positioning.

GPS origin
        GPS is the abbreviation of English Global Positioning System. It started in 1958 as a project of the US military and was put into use in 1964. The main purpose is to provide real-time, all-weather and global navigation services for the three major areas of land, sea and air, and for military purposes such as intelligence gathering, nuclear explosion monitoring and emergency communications. By 1994, a GPS satellite system consisting of 24 satellites with a global coverage rate of 98% had been deployed.

How to save yourself by GPS tracker
1, using the phone's built-in GPS chip, the following Apple mobile phone as an example. Turn on the compass and you can determine your GPS coordinates by using the two numbers "Northern Latitude" and "East" below.
compass

2. Place the acquired coordinates on the Gaode map to get the current location and view the route. (Of course, it can be Baidu map, Google map, see your usage habits)
Since mobile phone GPS positioning generally requires online map service, that is to say, it is necessary to connect the network when there is a signal, and upload the data and then mark the location on the map to achieve the purpose of positioning. However, this positioning method can only be used in the signal area, once it leaves the signal coverage area, there is no way to use it. And even in areas with signals, online GPS positioning will fail due to issues such as mobile phone traffic costs. This way we need to use offline maps for GPS positioning. The reason why offline maps can use GPS positioning without being connected to the Internet is because we download the map data to the mobile phone.

3, pay attention to the power of the phone
The GPS chip of the smartphone needs to receive the broadcast data of the satellite in real time to calculate and determine its position. Since the position is constantly moving, it is necessary to continuously receive the spatial coordinate data of the GPS satellite for calculation. This process consumes a lot of CPU and memory, and the power consumption of the mobile phone is also very large, and it is easy to run out of power. So you need to pay attention to the power of your phone.

4, travel essentials - charging treasure
Traveling outside, if you don't have a 20,000 mAh charging treasure, you are embarrassed to go out. Nowadays, smart phones are big consumers of electricity. In the event of an emergency, the mobile phone is guaranteed to have sufficient power to alarm and use GPS.

What are the meanings of these five parameters in GPS tracking product

GPS tracking product s have a lot of parameters, these parameters have their own meaning, here I will introduce the significance of these five parameters here. 1.The chip The chip mentioned here can be broadly referred to as the chipset used in the car GPS tracking product, and it is also the core part of the GPS tracking product. It is mainly responsible for GPS decoding signals, operations, and translation into positioning data. At present, the products purchased on the market are only chipsets produced by several companies. The performance of the chip, in fact, for the traditional closed system PND, it does not mean much. It is already sufficient to meet the positioning work. Therefore, what kind of chip is used, in fact, the difference in the experience of the user experience is getting smaller and smaller. 2.The number of channels What is the number of channels? It refers to the number of channels that a product chip can simultaneously receive satellite signa

How to start the wireless GPS tracker sleep state?

图片
Similar to mobile phones, hibernation is to reduce energy consumption and extend the use time. The wireless GPS tracker is the same as the GPS tracking device with its own power supply. Its battery capacity is limited; the battery life is determined by its work. The frequency is determined. Therefore, in order to improve the battery storage capacity of the wireless GPS tracker and extend the duration of its use, most GPS positioning manufacturers will set a sleep mode on the device to reduce battery consumption. So, how does the wireless GPS tracker initiate sleep? Let me give you a brief introduction. If the GPS tracking device is required to enter the sleep state, the GPS device must first have a sleep mode. However, not all wireless GPS tracking devices currently on the market have a sleep mode. Therefore, everyone should first understand before purchasing. Imagine if the product itself does not have this feature, how can it be enabled? Purchase Notes: Currently, th
