- Q: Principle and application of GPS
- GPS principle is simply to determine the target coordinates through the navigation satellite, and then map coordinates to determine the specific location of the target. GPS positioning principle is based on the high speed motion of the satellite instantaneous position as the known starting data, the use of spatial distance resection method to determine the location of the point to be measured. The global positioning system is a radio space positioning system, it uses the navigation satellite and the ground station to provide all-weather and global high precision, continuous and real-time three-dimensional coordinates (latitude, longitude, elevation), three-dimensional velocity and location information anywhere on the earth's surface for positioning and navigation.
- Q: How much is the platform cost per month after the installation of GPS positioning system
- Simple to tell you about the composition of the GPS positioning:1, you need to have a GPS locator, which is the hardware device;2, the need for a physical card, this card is mainly through the joint locator card GPRS upload location information in the access position, the IOT cartoon vulgar point is that mobile phone card, but the card is only the flow of things, can not call card;3, to which you can query the GPS positioning platform position, generally show the way through the map display directly installed GPS locator vehicles or personnel location information specific to the longitude and the approximate distance apart of various buildings;The above three is what you want to be established;The general need to spend is to buy the cost of the GPS locator, the United States and the United States card monthly fee, as well as the use of the platform fee; the United States and the United States are generally charged directly to the mobile card or linkage operators;Each GPS positioning platform software card developers are different, like a paper spill GPS locator I use is free, platform services, like car life GPS positioning platform is their own research and development, it is generally free or low; I will give the mobile node per month IOT card monthly, then the original purchase cost locator;But if you do not belong to the locator direct sales or not the manufacturers own research and development, the general charges are relatively expensive, after all the software development business to manufacturers received money, manufacturers or agents, agents and then charge you, this is probably!If it is not their own research and development of the positioning platform, then, if free, then most of the GPS positioning platform is not guaranteed after sale, after all, software developers do not have income, where there are people in vain to maintain the platform!
- Q: What are the four global positioning systems?
- China's Beidou satellite navigation system and the United States, GPS, Russia's Glonass, the European Galileo (Galileo) and known as the world's four largest satellite positioning system.
- Q: If the use of GPS positioning products which brand is good?
- Second questions;The proposed use of Beijing Lei Zhaoan Technology Co., Ltd. R & D and production of the focus of the old air defense lost products "coordinates", the positioning performance of a stable, full power can be used for about three days, small size. I used it for my father. All aspects are good, so I recommend to you. Hope to solve your problem.
- Q: GPS if you can not use the military code to crack the military GPS high-precision positioning?
- 1, since it is "secret" crack, even if the people's Liberation Army will tell you?2, this involves GPS channel coding problem (I just took a course last Saturday), and crack the password is completely different concepts of the two. You confuse this crack with the password. It is a very complicated process to encrypt the spread spectrum codes of military channels. I learned one semester is not fully understood... Is spreading code added scrambling encryption and interference technology etc.. And the channel cycle is at least a few days, to try to crack do not want to think.
- Q: What is the meaning of the GPS locator LBS?
- It includes two meanings: the first is to determine the location of the mobile device or user; secondly, to provide various information services related to the location. Refers to the positioning of the various types of service systems, referred to as positioning services, and another called MPS-Mobile Position Services, also known as mobile location service system. As to find the current location of mobile phone users, and then find the name of mobile phone users at the current location within 1 km of hotels, cinemas, libraries, etc. the gas station in the city of Shanghai in the range of 6340 square kilometers and address. So LBS is to use the Internet or wireless networks, fixed users or mobile users, to complete the positioning and service two functions.
