Differences between lbs and GPS Positioning

What is lbs positioning? Location-Based Services (lbs) includes two meanings: determining the geographical location of a mobile device or user, and providing location-related information services. It refers to various service systems related to positioning, referred to as "positioning service", and is also called MPs-mobile position services, also known as "mobile positioning service. If you find the current location of the mobile phone user, then, search for the name and address of the hotel, cinema, library lbs, and gas station within 6340 square kilometers of Shanghai. Therefore, LBS is to use the internet or wireless network to complete the positioning and service functions between fixed users or mobile users. LBs positioning Insufficiency: This base station location method has a large error range in the absence of base stations, and in some cases, the location function cannot be implemented without a base station. Therefore, if the mobile phone uses lbs location, make sure that you have a service base station in your location. What is GPS Positioning? GPS is the Global Positioning System ). Simply put, this is a satellite system composed of 24 satellites around the world. This system can ensure that four satellites can be observed at any point on the Earth at any time to ensure that the satellite can collect the longitude and latitude and height of the observation point, in order to achieve navigation, positioning, timing and other functions. This technology can be used to guide airplanes, ships, vehicles and individuals to arrive at their destinations safely and accurately along the selected routes. The Global Positioning System (GPS) is a new generation of spatial satellite navigation and positioning system jointly developed by the US Army of land, sea, and air in 1970s. Its main purpose is to provide real-time, around-the-clock, and global navigation services for the land, sea, and air fields, and to be used for intelligence collection, nuclear explosion monitoring, emergency communication, and other military purposes, it is an important part of the global strategy of the U.S. monopoly. After more than 20 years of research and experiments, at a cost of $30 billion, by March 1994, 24 GPS satellite constellations with a global coverage rate of up to 98% have been deployed. The GPS Global Positioning System consists of three parts: the Space part-GPS constellation; the ground control part-the ground monitoring system; the user equipment part-the GPS signal receiver. Advantages of GPS positioning: The biggest difference in GPS positioning is accuracy, and GPS Positioning can query the motion track on the Internet. Therefore, it is widely used.
