FAQ
- What does GPS mean
- GPS prospectBecause of all-weather, high precision and automatic measurement of the characteristics of the GPS technology has, as an advanced measurement tools and new productivity, has been integrated into the national economic construction, national defense construction and social development in various applications.With the rapid development of the global economy and the end of the cold war, the U.S. government announced during 2000 to 2006, under the premise of ensuring national security is not threatened, cancel the SA policy, GPS civil signal precision is improved in the global scope, single point positioning by use of C/A code accuracy increased from 100 m to 20 m, application this will further promote GPS technology, improve productivity, work efficiency and scientific level and people's quality of life, stimulate the growth of the GPS market. According to experts predict that in the United States, just the car GPS navigation system, after 2000 the market will reach $3 billion, while in China, the car navigation market will reach 5 billion yuan. Visible, GPS technology market prospects are very impressive.
- GPS locator what brand is better? What is the most stable platform?
- but also support SMS features, usually you do not have a computer when you can send shortWay to query the location of their own vehicles, fast oh!! Prices are relatively cheap, do not accept the product costs, only a few hundred dollars a year networking fees
- Function and application of GPS locator
- 3, setting attendance report time, attendance of all employees yesterday to see, can also view a list with the attendance of employees in a period of time. Detailed attendance list can be used to view the positioning time and location of all punctuation to describe the information, and to support the export of Excel forms to facilitate the management of enterprises. 4, system management system provides the perfect setting for management, employee information can be flexibly set, for employee grouping, convenient management, all levels of users with tight access control, security information 1) SMS sent into the SMS center, click the "text", select the terminal name needs to be sent. Fill in the content of the message to be sent, and click the "send 2) receive SMS messages into the SMS center, click the" messages ", can receive 3 SMS inbox view) to view selection time, click the" search ", you can see all the time the message received 4) has sent the information to choose view view time, click the" search ", you can view all the messages issued during the period of
- 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!
- GPS locator really can be used for car theft
- With this full-time can open the oil；The gentleman does not guard against small things
- 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.
- Car positioning display offline is how
- There are several reasons for the following reasons:1, GPS locator SIM card money;2, your car is in a signal blind area, equipment can not upload information;3, GPS locator communication module (GSM module) out of the question;4. The GPS antenna is broken;5, the device is dead;6, the sensitivity of the GPS module can not be fixed.
- Who knows the GPS tracker or locator that can be used in no man's land? Thanks
- Yes, Baidu, Bo Xiang Heng fly technology,You can go online to see 021-GPS
