- Q: What is a GPS positioning system?
- GPS system compositionGPS system has three major components, namely, the space constellation, ground monitoring and user equipment. Space constellation in GPS 24 satellites distributed evenly in 6 orbital planes, orbital plane angle relative to the equatorial plane is 55 degrees, the angle between the plane of the orbit is 60 degrees, each satellite orbital plane 90 degrees, either on the satellite orbit plane than in the west adjacent corresponding satellite orbital plane the lead on 30 degrees. The average altitude of the satellite orbit is 20200km, and the satellite running period is 11 hours and 58 minutes. Each satellite every day about 5 hours above the horizon, and at the same time the number of satellites above the horizon varies with time and location are different, can be 4~11; the ground monitoring part of GPS at present mainly by the distribution in 5 ground stations around the world, including the injection station inspection station, master station and information. The space part and ground monitoring part of the GPS is the basis of the navigation and positioning of the system which is widely used by the user, which is controlled by the United States. The user equipment of the GPS is mainly composed of the receiver hardware and processing software. The user receives the GPS satellite signal through the user equipment, obtains the user position, the speed and so on through the signal processing, finally realizes uses GPS to carry on the navigation and the localization goal.
- Q: What are the features of the GPS car locator
- 2 remote tracking and monitoring center in the monitoring software on the GPS terminal timing tracking settings can be set to a fixed time to upload location information and status information, once set up, GPS terminal will according to the monitoring center issued the instruction request timely upload needed information monitoring center;
- Q: I bought a real carpenter car GPS locator, and then I clearly insert the boot how to display is not enabled? Which God knows?
- On the market most of the GPS locator is 100 meters range, if the location to be more precise, is an GPS car loan location is within 30 meters, the location is also according to the platform, if you use the GPS locator platform is not stable, it is in vain. The platform, GPS positioning platform three six five IOT is very stable.
- Q: How to detect whether the car installed jgps locator
- There are friends in the past to buy a Taobao through the star, the brand is to stop after the signal can not find. If it is other brands, some do not sleep, you will be measured in that way, will soon find a signal.
- Q: Phone can not locate GPS
- You:According to your description recommended: 1 recommend that you enter the set - Application Manager - all navigation - clear data suggest search 2 10-20 clock between car parking search 3 proposed to replace its position around the buildings to try the 4 navigation search positioning around the environment, gas and other elements for which suggest that you try the 5 closing machine restore factory settings you open: Set - reset - recovery plant (due to machine restore factory settings lost machine data suggest important data than the prior electric, video and pictures with the backup) through accurate positioning according to purchase invoice, please bring your bag card machine to send Samsung service by the engineer to check the machine and processing
- Q: the battery can be replaced, frost resistance, waterproof, when the horses mobile phone can receive text messages over speeding horsesIt is best to wear a belt, worn on the neck of the livestock is convenient, not easy to fall, similar to the release of the northeast tiger Putin that is the best
- 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: Why can not locate the vehicle GPS locator
- Hello.It is possible that the GPS will not be able to locate if it is disturbed or cannot receive satellite signals. Recommended to open the place to try. If not, it may be caused by damage to the antenna or locator. Hope can help you! Car problem, ask car master! If you do not understand the landing car master to find me!
- Q: My friend bought a car to install satellite positioning system I am interested in my friend explained that I would like to ask who knows the professional interpretation (product principle) who knows who
- It can be seen that the role of the GPS navigation satellite system is to continuously transmit navigation messages. However, because the user receives the clock and satellite machine using a carrier clock may not always synchronized, so in addition to the 3D coordinates of X, y, Z users, but also the introduction of a t that is the time difference between the satellite and the receiver as unknown, and then use the 4 equation the 4 unknowns out. So if you want to know the location of the receiver, at least to receive the signal of 4 satellites.The GPS receiver may receive for accurate timing information to nanosecond time; for forecasting ephemeris in the next few months which the approximate location of the satellite; used to calculate the required positioning satellite coordinates of the broadcast ephemeris, the accuracy of several meters to tens of meters (each satellite is different at any time change) and GPS system information; such as satellite status.The GPS receiver can get the distance from the satellite to the receiver by the measurement of the code, because it contains the receiver satellite clock error and atmospheric propagation error, it is called the pseudo distance. The pseudo distance measured by the 0A code is called the pseudo distance of the UA code, the precision is about 20 meters, the pseudo distance measured by the P code is called the pseudo distance of the P code, and the precision is about 2 meters.

- (four) 1 in order to avoid the installation of equipment failure, one should try to avoid hidden; 2 and the emission source together, such as wireless burglar alarm, reversing radar, car and other communications equipment; 3 can be used to tie fixed, or wide sponge strong double-sided adhesive paste; 4 GSM antenna device and the GPS antenna should be installed to ensure the positive upward (sky). Bu implied condition GPS module SiRFStarIII to accept every two output position data, usually $GPRMC to streamline the data format, including latitude, longitude, speed (nodes), motion direction angle, year, month, minutes, seconds, milliseconds, positioning data is valid or invalid, and other important information. The statement is as follows: $GPRMC,,,,
