1. What is the GPS module?
The GPS module is actually a signal receiver who receives the GPS satellite. He can transmit with mobile phones and computers through networks, Bluetooth, wired transmission and other methods. Treatment through the GPS software in a computer or mobile phone.
Everyone should know the radio. He is a C/A code signal that is similar to the radio and demodys the satellite broadcast. The GPS module does not spread the signal itself, which is a passive positioning.
2. The positioning principle of the GPS module
The GPS module uses GPS to locate satellites, composed of 24 satellites (21 working satellites; 3 spare satellites). It is located over 20200km from the surface of the ground, with a operating cycle of 12h. The satellites are evenly distributed on the 6 rail surfaces (4 per track surface), and the orbital angle is 55 °. The distribution of satellites allows more than 4 satellites to observe more than 4 satellites around the world, and then compose multiple satellite data to know the specific location of the receiver and can pre -storage in the satellite.
Due to the errors of satellite running track and satellite clock, the effects of atmosphere on the signal on the flow layer and ionization layer on the signal, making the positioning accuracy of civilian GPS only 10 meters. In order to improve the positioning accuracy, the differential GPS (DGPS) technology is generally adopted to establish the benchmark station (differential table) for GPS observation. The accurate coordinates of the known benchmark stations are used to compare the observation values to obtain a correction number and release it outside the outside world. Essence After receiving the correction number, the receiver compares it with its own observation value, eliminates most of the errors, and obtains a more accurate position. Experiments show that the positioning accuracy can be increased to 5 meters by using differential GPS.
3. Based on GPS module bus logistics transportation management
Faced with the continuous rise in domestic oil prices, the operating costs of many logistics companies in transportation are increasingly larger. Drivers steal oil to sell oil during transportation, and logistics companies are at the same time facing customers to reduce logistics costs. You can produce the location and status of the vehicle during transportation through the GPS module, and transmit the current position to the network through the SIM network to facilitate the management center to master the real -time transportation progress of the cargo. In addition, if there is a driving failure, traffic obstruction, and emergency situation during transportation, you can learn about the issuance point through the GPS module, and dispatched the vehicle closest to the incident point for rescue to ensure that the safety and transportation progress of the transport personnel will not be accepted.
4. GPS module application
The GPS module can be developed into different application systems according to different application environments. As described above, the logistics and transportation management system, leasing industry system, bus management system, elderly and child care system, ship's ocean navigation, and water entry into Hong Kong diversion and so on.
