Q:What is GPS Mu meter ah, with the general said that the GPS measuring instrument what is the difference?

The amount of words on the handheld GPS, Magellan can be both economic and affordable.

Q:I would like to ask the GPS handset and GPS receiver (Surveying and mapping qualification application needs) is there a difference? If yes, what is the difference?

1. GPS is a geodetic instrument, with an accuracy of CM, generally for the millimeter,,Divided into (1) pure static type, such as the South Star of the North Star, the accuracy of mm, now the basic domestic,,(2) RTK, RTK can do is use, carrier phase measurement, the precision is cm level, RTK mobile station must have the control hand book, like television and remote similar, but now there are a lot of hand book can be used as handset2. The handset is generally rough field positioning equipment, navigation for mobile phone use, the general size, precision grade m, now can to about 20cm, and can be used for RTK mobile station use (need to access the base station) can reach cm level.Surveying and mapping qualification applications require geodetic measurement equipment, that is, 1.Now domestic GPS, such as the Haida, the south, China, etc. can be measured, not expensive

Q:Handheld GPS brand rankings

Set of SIBAO products awarded the Beijing independent innovation product identification certificate, satellite navigation and Engineering Excellence Award and other professional awards. At the time, location, navigation and other comprehensive applications, Unistrong successful implementation of hundreds of large projects, services in many national key projects, won the national honor.

Q:How do I still stay in the GPS navigation, GPS monitoring of the primary idea? FiveBusiness services, thank you!Future business services

1 power, telecommunications, telecommunications and other network time synchronization2 accurate timing of admission3 accurate frequency of admission1 geodetic measurements of various levels2 Road and various line lofting3 underwater topographic survey4 crustal deformation measurement, dam and large building deformation monitoring5.GIS application6 construction machinery (tyre crane, bulldozer, etc.) control7 precision agricultureAt the present stage, it is mainly used for the security of vehicles and the management of personnel vehicles. With the continuous development of social economy, more and more vehicle users, GPS will gradually get wide application, on the stage of the car is enough for your service. Prospects can still be Lin Shijie GPS

Q:What do you need to test for GPS?

As a high-tech product, GPS has a very complex technical parameters. However, as people's living standards improved rapidly, more and more ordinary people began to pay attention to the positioning and navigation tools originated from the military. Because the convenience it brings is unprecedented. In order to let everyone out of all the technical parameters of GPS receiver, no longer confused at the time of purchase, the author selected six of the most important technical indicators, one by one to explain to you. 1 parallel channels on the market most of the GPS receiver is a 8 channel, 12 channel, the 16 channel, which allows them to continuously track the information of each satellite. Some GPS devices only have 2 to 5 parallel channel receiving satellite signals, because the average of 8 satellites are visible, which means that the GPS receiver must visit each of the satellites in order to obtain information about each satellite. All of our products are in Shenzhen channel 16 channel, multi-channel parallel GPS receiver, including the advantages of rapid cold start and initialization of satellite information, but also in the forest area can have a better reception. General 12 channel receiver does not require an external antenna, unless you are in a bad environment conditions such as closed space, such as the cabin, the car. 2 the sensitivity of the GPS satellite signal to the ground has been very weak, as well as ground wireless communication clutter interference. The lowest traceable signal strength of the GPS receiver determines how much useful signal is received. A GPS receiver with a lower minimum tracking signal strength has a higher sensitivity, and can receive more available satellites under bad conditions

Q:Handheld GPS charge is not into electricity what is the reason

Reason analysis:1, battery damage. 2, system failure. 3, charger reasons or bad contact.

Q:How to upgrade handheld navigator

Some 4S shop can;Read the instructions, there are generally USB mouth, then you can upgrade the computer practice;There is a memory card, then you can remove the plug on the computer upgrade;Or get the computer city to see it.

Q:Magellan GPS handheld why so many people choose not to say that the map is not good

Magellan GPS handheld maps are not even, it is said that the map even money! No need ah.

Q:Handheld GPS and mobile phone GPS what is the difference?

Handheld GPS also supports GPS compass navigation and map navigation as well as other more professional GPS applications; mobile GPS can work with fewer, more consumer grade product applications

Q:I am ready to go to the field to go to college, but I do not know how to buy a handheld GPS, I hope you recommend. The most important thing is easy to carry.

Younger brother, buy a smart phone, ranging from several hundred dollars to several thousand dollars, as long as the GPS module on the line, understand it?I'm not talking about it, as long as the smart phone with GPS module, you can use when GPS, can be used to drive, you can certainly use a walk. Even if there is no GPS die fast, with a cell phone signal can be positioned, but not too accurate. Hundreds of meters.In addition, you go to college, do not use smart phones, students are not afraid of jokes? Buy a Android system on the machine line. Cheap on a few hundred dollars.You say you take a hand-held machine, and then take a cell phone to go out, trouble is not trouble?
