Wide application of GPS

With the advent of the "3G" era and the prevalence of "smart" and "mobile internet" concepts and products, the "Smart" wind has been blowing in the GPS market, and smart navigation is getting hotter and hotter. GPS provides all-weather high-precision continuous real-time 3D navigation and positioning capabilities. The new products of various types of navigation devices are constantly emerging in the market, ranging from mobile navigation smart navigation systems we know well to large-scale military navigation devices. Although GPS navigation products are facing more and more pressure from GPS-enabled smart phones, the GPS market is expected to experience a brief outbreak with the arrival of peak travel seasons in September and October.

Here to talk about the application of GPS in various aspects:

1.GPS application in logistics companies:

TBEA Shenyang Transformer Group Co., Ltd. used satellite maps for logistics and transportation to find the goods. A storage and transportation worker at his factory entered the job number of a transformer on a GPS that was slightly larger than the mobile phone, and the electronic map immediately Shows more than 30 host and box storage locations. It can be seen that using GPS to find goods is much less time-consuming than manual search, which greatly improves work efficiency and facilitates our daily work.

2. GPS applications in the military:

According to recent international news reports: North Korea's GPS interferes with US-Korea military exercises. South Korea’s “Korean Daily” quoted the report of the Korean Ministry of National Defense on the 9th that an RC-78 reconnaissance aircraft of the US military stationed in South Korea took off from the base at 8:30 on March 4 and met with the sea from North Korea and Kaesong in the afternoon of the same day. Intermittent signals from minutes to 10 minutes, an onboard GPS malfunction, and an emergency landing after approximately 45 minutes. The report said that the reconnaissance plane was participating in the ROK-US joint military exercise.

3.GPS application on ships:

The port and shipping management department installed a GPS system for most of Taihu Lake's shipowners. If there are stormy conditions, they will notify the shipowner in advance and close the port. They do not need to rely on their own experience to speculate when the storm is coming and when they can sail. The existence of GPS on ships is a life-saving bell for boatmen. In the event of an emergency, the shipowner can press the “one-touch alarm” button. After the command center receives the alarm, it will immediately dispatch the marine boat to rescue him. In some cases, GPS has also radiated powerful functions to other areas. It also helped the police solve the case.

4. GPS application in positioning:

Recently, a batch of GPS locators will be distributed free of charge to persons with intellectual disabilities, mental disorders and low-income families in Dalian who are over 60 years of age. Among them, if accidents such as loss occur, family members can quickly find out through GPS positioning. . When related groups carry and wear GPS locators, they can use the communication operator's network, terrain and geographic information system, and use communication signals to achieve positioning and whereabouts inquiries, so that their relatives and guardians can search through the Internet in a short time. To the immediate location of the carrier and the wearer, once the elderly or the disabled have been lost, they can find someone according to “positioning” as soon as possible.

5.GPS application in car navigation:

I think that for the GPS car navigation system, everyone is certainly not unfamiliar with it. Nowadays, a variety of car navigation devices are popular in the market, aiming to protect the safety of the users and the convenience of travel. Despite its diversity, its basic functions are similar. Today, most car navigation systems have the following features: smart navigation, accurate GPS positioning, detailed navigation map data, multiple path planning, full-screen touch operation, full 3D real-time voice navigation, search speed, GPS search speed, accurate positioning , Comprehensive search information; New 3D real-view map navigation, clearer vision, easier navigation; FM transmitter function, support FM transmitter, navigation voice can be directly converted to car audio sound; fixed speed function, GPS built-in DSA fixed Electronic dog, can be pre-alarm red light, fixed speed, electronic police monitoring, radar speed, speed limit camera, etc.; support for MP3 playback, built-in Lianliankan, mine clearance, Tetris, Snake and other classic games, GPS comes with These entertainment features allow car owners to relax properly.

6.GPS application in indoor positioning:

For precise positioning, nowadays mobile phones and some other standard GPS receivers cannot work indoors. However, the current status quo is that there are many public and commercial services, including search and rescue, fire rescue, and some location-based services that require accurate indoor GPS positioning. Among these requirements, the accuracy requirement is particularly important. For example, in a fire, the indoor GPS can be accurately positioned to know which layer a person in danger is trapped. In order to meet the demand for higher-precision GPS positioning, Japan will soon introduce indoor GPS positioning: the IMES system (Indoor messaging system).

The system forms a seamless indoor positioning system through some signal transmitters preset in the room, modified embedded firmware in the mobile device, and corresponding information servers. At present, Hitachi Hitachi, a well-known company, has made further progress in this area.

Positioning equipment with IMES function normally uses GPS satellite positioning in places with strong outdoor signals, and uses signal transmitters installed in buildings inside for indoor positioning. Although slightly different in content, the signal structure is the same as the signal transmitted by GPS satellites. Therefore, mobile phone and other GPS signal receiving devices do not need to change the receiving system such as the antenna and the signal processing module.

The IMES transmitter will send signals similar to those of GPS and QZSS (Japan Positioning Satellite System). Through the corresponding positioning equipment, it will give an indoor 3-dimensional positioning with an accuracy of 10 meters. The transmitter will meet low power consumption, low cost, and no impact on GPS and QZSS, providing highly reliable location services so that users can know which floor, which room, which shopping center they are on, Parking lot and so on.

It is expected that after the launch of this IMES system, the development of positioning equipment will be further promoted, and the demand for personal positioning equipment will also be greatly increased.
