Q:Younger brother bought a used car how to know where his GPS positioning system installed
Possible position:1 front windshield above the roof lights;2 in front of the windshield trim panel inside the hidden;3 hidden behind the dashboard;4 door partition;5 under the trim panel under the windshield;6 front bumper, need to pay attention to waterproof;7 windshield wipers, need to pay attention to waterproof;Note: if the windshield is covered with a metal insulation or heating layer, it will reduce the GPS received signal, resulting in GPS abnormal. Pay attention to the replacement of equipment installation position.
Q:Is the relay of the GPS locator installed in the front or rear of the high voltage package?
You put the relay directly connected to the battery, the relay into the 12V power on the line
Q:The prairie cattle wearing GPS locatorRequire long standby time, at least a month,
3, the platform function of the three statistical analysis of data (automatic attendance, mileage statistics)Position attendance: employee attendance automatically generated, performance evaluation. It can also be used to check the position and location of all punctuation information through detailed attendance list to facilitate the management of personnel.Visit statistics: automatic generation of outworker visit statistics, the work of field staff to fully understand. Improve the executive ability and improve the management.Visit details: the basic situation of the automatic generation of outworker visit report in detail, understand the field staff to visit customers time and visit customers.Customer visit statistics: automatic generation of attendance reports, customer visits, automatic statistics, etc.. To achieve cost control, improve the implementation of the visit, and continuously improve enterprise management.Sign in location details: report to the current location information, accurate position information on the map.
Q:What are the things that need to be paid attention to in the process of using GPS locator
Installation, then look to buy wireless or wired, there is not a strong magnetic, the following points should be noted when installing:1 in order to avoid damage to the thief, the device should be selected as far as possible concealment;2 to avoid the launch of the source together, such as wireless reversing radar, anti-theft devices, and other vehicle communication equipment;
Q:There is no need to insert the SIM card GPS locator?
No, you have to insert the card, you can buy a monthly card, it is only the amount of communication fees, and very cheap
Q:Way strong ET100 locator GPS machine fault 100
A line is not good, bad contact, two machines have problems,
Q:What does GPS mean
GPS principle24 GPS satellites orbiting the earth at an altitude of about 12 thousand kilometers from the ground, making it possible to observe more than 4 satellites at any point on the ground at any time, at any point in the.That due to the precise position of the satellite in the GPS observations, we can get the satellite to the receiver distance, the distance formula of three-dimensional coordinates, using 3 satellites, can be composed of 3 equations, solved observation point (X, Y, Z). Considering the error between the satellite clock and receiver clock, in fact there are 4 unknowns, X, Y, Z and clock, which requires the introduction of fourth satellites, the formation of 4 equations to solve, in order to get the observation points of latitude and longitude and elevation.In fact, the receiver can often be locked more than 4 satellites, then the receiver according to the distribution of the satellite constellation is divided into several groups, each group had 4 teeth, and then through the algorithm selected a set of minimum error for positioning, so as to improve the accuracy of.Due to the orbit of the satellite, the satellite clock error, the impact of the atmospheric troposphere and ionosphere on the signal, as well as the artificial SA protection policy, the positioning accuracy of civil GPS is only 100 meters. In order to improve the positioning accuracy, commonly used differential GPS (DGPS) technology, the establishment of base station (differential Taiwan) were observed in GPS, using the known exact coordinates of the base station, compared with the observed values, so that a number of amendments, and released. After receiving the correction, the receiver compares with the observed values, eliminates most of the errors, and obtains a more accurate position. The experimental results show that the positioning accuracy can be increased to 5 meters by using differential GPS.
Q:GPS and tracking locator are two different things,
The information sent to the software platform, you can check your car through the platform position. The effect of GPS tracking anti-theft is really very good, I would like a fitted, because my bike is stolen, I have lost two bikes, Xiangqilaijiu sad, so I must want to buy a GPS locator, the running track of who would come to steal you can see the car through the platform to find the car.
Q:Bad weather will affect the GPS locator accept signal
Hello, such as clouds thick fog and haze will affect the situation
Q:Is the GPS positioning system based on electromagnetic waves?GPS system depends on electromagnetic wave location. Is this the right or wrong?
GPS global satellite positioning system consists of three parts: the space part - GPS constellation; ground control part - ground monitoring system; user equipment Part - GPS signal receiver
