Vehicle Tracking Device For OBD II is your good choice. 1. Definition OBD is the abbreviation of On-Board Diagnostics, which means on-board automatic diagnosis system. The OBD system monitors whether the car's exhaust gas exceeds the limit at any time from the operating condition of the engine. Once it exceeds the limit, it will immediately issue a warning.
Tracking Device GPS Sensor is your good choice.At present, GPS tracking devices are widely used in various applications such as panic alarm for the elderly, child monitoring, valuables tracking, vehicle tracking and so on. For example, on April 15 this year, the British "Daily Mail" reported that this year, a family in Nottingham, England, decided to install a GPS tracking device for their pet turtle because it had run away from home many times.
Key factors affecting the work of Realtime tracking GPS tracker:1. The US Department of Defense SA satellite signal interference. (Satellite signals are controlled by the United States, and signal services may occasionally be interrupted)
The OBD Tracker For All Car is a plug-and-play locator without complicated installation steps. The OBD interface position of various models is different. The installation is also very simple, just like inserting a USB flash drive. Tools/Materials OBD locator Models with OBD interface Location monitoring platform SIM card Method/Step Open the device cover and insert the SIM card into the card slot correctly. Close the cover. Locate the OBD interface of the car and open the lid; insert the
Tracking Software Platform Supports More Than 10000 Devices is a very powerful software platform.The predecessor of the GPS system is a Meridian satellite positioning system (Transit) developed by the US military. It was developed in 1958 and officially put into use in 64. The system works with a star network composed of 5 to 6 satellites, and it bypasses the earth 13 times a day at most, and cannot provide altitude information, and the positioning accuracy is not satisfactory. However, the Meridian system enabled the R&D department to gain preliminary experience in satellite positioning and verified the feasibility of positioning by the satellite system, laying the groundwork for the development of the GPS system.
1. The essence of GPS positioning is that the GSP receiver receives GPS signals and calculates its own longitude and latitude. 2. The set of points whose distance to a fixed point is equal to the fixed length is a circle in the plane, and a spherical surface in three-dimensional space; the set of points whose distance difference to two fixed points is a fixed length is a branch of a hyperbola in the plane, In the three-dimensional space is a surface of the hyperboloid.
