Q:Handheld GPS buried in the soil there is a signal: It depends on how deep you buried the darker the GPS signal, and must ensure that the GPS antenna upward, the above can not be covered with metal objects

Q:How do I still stay in the GPS navigation, GPS monitoring of the primary idea? FiveBusiness services, thank you!Future business services: 6 people travel and adventure7 personal communication terminal (with mobile phones, PDA, electronic map integration)8 time synchronization of electric power, post and telecommunication9 accurate timing of admission10 accurate frequency of admission

Q:Handheld GPS navigation is what? Where to buy handheld GPS navigation, how to select GPS navigation?: Select the main consideration of the following issues on the line:1, GPS receiving capacity, in the interior, the streets can be measured on a few stars, while looking at the speed of the search star? If a place for 2 - 3 minutes accurate positioning can be used2, the map is the latest, often used to check those routes3, battery life is how long to ask4, accessories, such as support, car charge, the size of the memory card should be clearly presentedThe location of the purchase is usually in the car decoration department or the electronic mall or digital products store salesAffordable mall can look at the old brand, operating for many years, where I bought the electronic dog

Q:Can you buy a good handheld GPS in China? FiveTrouble master recommended several professional handheld GPS brand, in addition to handheld GPS can speed it? Thank you!!: If it is used, there is no difference.

Q:In addition to the parameters, that is the problem of the machine, what method can reduce the error of these two machines to a minimum. Because, at the same time to find a coordinate. The gap is too big.: GPS was in error with 10 meters, with the star search results, related to the environment, if the precision is high, as long as the use of handheld GPS submeter or handheld RTK

Q:How about the accuracy of the GPS handset?: So the selection depends on your needs the function and budget. Haida official website mall "mobile MGIS mall".

Q:I bought the way k20s, this handheld GPS how: Choi way handheld GPS feel that you can also be in the last year, the Zhengzhou Bureau of Surveying and mapping seems to be called the wide Han instrument that home to buy, so there is no problem with it, the price is not expensive.

Q:What is GPS Mu meter ah, with the general said that the GPS measuring instrument what is the difference?: GPS Mu meter also known as land area measuring instrument, handheld meter meter, etc.. Integrated computational methods for understanding and intelligent high precision GPS positioning system, the precise area of the handheld computer system, can realize the irregular area of real-time measurement and dynamic graphical display and intelligent data processing and storage.GPS measurement of the meter is different from the general GPS measuring instrument is based on the latitude and longitude of its area calculation function, general GPS is generally used for positioning.

Q:Highway measurement with GPS I do not know which of the base station settings and mobile station settings I are very vague, to the instrument to build a coordinate system how to build the relevant issues to me: For long tunnels, the conventional measurement of large bridges has the following limitations:1, long tunnels, bridges and other structures generally require the measurement level of four or more. With conventional measurement methods, often adopt the measure to increase the number of methods to extend the observation time, time consumption and labor consumption to try to improve the accuracy of.2, the long tunnel and bridge for the complex terrain region difficult, conventional control measure for visibility and network shape, often cut down the workload is quite large, so the measurement of the cost of a large, hard work.Link control network of high precision 3, long tunnel and bridge and low precision and route network, although with adjustment methods can be overcome, but because of the terrain conditions are difficult, the measurement workload to its connection, and is not too easy. In practical work, the control of the structure and the measurement of the route are often out of touch.

Q:Seeking the similarities and differences between RTK and GPS: GPS: is the satellite positioning system in general, narrow sense refers to the GPS satellite, and the narrow sense refers to all can receive GPS signal equipment; RTK refers to the dynamic real time difference measurement, it also refers to the difference can be used for real-time dynamic measurement equipment. The difference between the two measurements from speaking: GPS contains RTK, also includes some precision lower grade equipment, such as the Garmin handset, handset, GPS meter level navigation etc..
