- Q: Car GPS locator which is good
- Everyone's needs are not the same, it is best to choose the right GPS based on your actual situation.
- Q: Chengdu GPS locator installed there
- Wuhou Avenue has a DDTxzx02 price quality effect is also ideal site
- Q: Use method of real carpenter locator
- 1 map useGPS with the use of a detailed map with the best results, but the domestic large scale map is very rare, GPS effect is subject to certain restrictions. "If you have the exact map near the destination, you can advance planning line, first map planning, making plans, in accordance with the complex situation and mileage line, set up one or more lines (ROUTE), readout route feature points, GPS input wiring the" legs "(legs), and some individual landmarks as landmarks (Landmark/Waypoint) input GPS. GPS manual input data, is a very troublesome thing, please think about each sign will enter the name and coordinates of more than and 20 alphanumeric characters, each alphanumeric according to up to 10 times the arrow to come out, ha ha, this is someone willing to spend a lot of money to buy connection and software, use the computer to upload the reasons / download data. Bring map! When traveling with the use of GPS to determine their location on the map, the two is in accordance with the direction of the direction of the target function, with the map to find the way forward. At the same time we must record the actual coordinates of each planning point, the best for each planning to build another railway line, can be used to backtrack, and may be returned as the actual route information stored for later use.
- Q: 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!
- 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.
- Q: Principle of GPS positioning
- 3 alarm (report)3.1, overspeed alarm: when the vehicle speed exceeds the preset speed of the monitoring center, timely report to the monitoring center3.2, the regional alarm (electronic fence): the monitoring center to set the scope of the region, the vehicle is beyond or into the preset area will be given to the monitoring and dispatching center of the corresponding alarm3.3, parking report: the dispatch center can be the history of the vehicle parking records in the form of text to generate statements, which describe the vehicle parking place, time and driving time and other information, and can be printed.3.4, emergency alarm: once in case of emergency (such as robbery etc.), please immediately press the emergency alarm button, the alarm to the monitoring center, monitoring center immediately will know you are in a state of emergency and the location of your. After verification, into the police to deal with the situation, to help you out. Note: once the emergency alarm button is activated, the device will immediately turn off the call function, but the message function is normal3.5, under voltage alarm, when the car battery voltage is too low, the car will automatically monitor the alarm center, the monitoring center duty officer to remind the user to charge the vehicle in a timely manner.3.6, cut line alarm, after the main battery is damaged or can not be powered, the built-in backup battery can continue to work to maintain the product, and the monitoring center to send a wire cut alarm.
- Q: Now the company unit to do vehicle management, with GPS locator is good?
- Certainly good! 1 cost saving: eliminate the driver at reimbursement of fuel costs, Gongjusiyong caused huge waste; 2 improve the regulation efficiency and service efficiency: recently the most appropriate distance, vehicle loading and unloading of goods timely call, reduce vehicle load, avoid the idle stop or driving distance and other conditions, greatly improving the use of vehicles the rate of 3; security: strong to avoid outsiders on the driver or vehicle or cargo theft hijacking.May wish to understand the optimal drive GPS locator, GPS anti-theft device, GPS monitoring vehicle management system. The production of affordable by the Shenzhen tanbit company, simple installation
- Q: Does UUGPS have an anti - rejection tracking locator?
- In other words, the city of Shenzhen science and Technology Industrial Co., Ltd. production are good
- Q: There is no device can detect the location of the GPS locator
- (four) rn1. installation points to prevent thieves damage, equipment selection should be hidden; and avoid rn2. emission sources together, such as wireless reversing radar, alarm, and other vehicle communication equipment; rn3. can be used to tie fixed, or wide sponge strong double-sided adhesive paste; rn4. device with GSM antenna and the GPS antenna should be installed to ensure the positive upward (sky).
- Q: Wrong track GPS locator equipment, track points about inconsistent with the actual position?
- Do you not see before the product platform, Liaoyuan star GPS positioning system, the trajectory is clear, the accuracy of 5-10 meters.
