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?

This is the case, GPS handheld refers to a thin hand, while the GPS receiver refers to the RTK host, equivalent to the base station in our industry said. The general application of Surveying and mapping qualifications are required for this application, referred to as RTK (1+1) set, level, theodolite, total station, walkie talkie, technical personnel.... And so on, are essential equipment.

Q:What factors affect the handheld GPS receive signal?

Active ionosphere, large canopy, high voltage wire, high building.... Have influence.

Q:My friend is in use, the difference is not big, professional handset (smart or Magellan bulky, but 3 case), but the price is expensive, but can not call and map is very rotten, endurance of 10 hours (dry battery) the mobile phone also has all the time. Know friends say, I mainly in the suburbs! Thanks

Three, the map of the differenceIn terms of the difference between the two maps is relatively large, most of the hand-held machine using contour map, the city is only as a secondary auxiliary. The mobile map is just the opposite, very detailed description of the city streets.Refer toThere is no road for GPS routing calculation. Popular said, handheld GPS to do is to draw a straight line to the destination, to determine their own inflection point. Handheld GPS will tell you to the destination: distance, course, yaw distance and other information (a lot of parameters, you can choose to display). In addition, handheld GPS also has to add a new landmark, through the software to draw their own waypoints, the average position of the measurement function, and even can measure the height and temperature, highlighting the degree of professionalism of its application.Cell phone navigation is very different from the former. GPS will be in accordance with the routing algorithm to calculate the nearest path, the premise is to have a detailed street map. GPS will tell you the right to turn right at the intersection. Mobile GPS can also search the starting point near the point of interest information, and can calculate the fastest path to reach the land.

Q:Handheld GPS navigation is what? Where to buy handheld GPS navigation, how to select GPS navigation?

Handheld GPS is mainly for GIS data acquisition, a lot of advanced GPS with PDA function, you can load navigation software for vehicle navigationBut the handheld GPS is mainly to do some engineering design, the main area can be measured, the location, and the boundary survey. GPS can do advanced vehicle navigation can also waypoint navigation, is a coordinate input to precise navigation to this position.Handheld GPS navigation is divided into 2 kinds, one is portable GPS navigation, one is used for surveying and mapping professional GPS handheld

Q:What is the difference between a hand-held GPS and a car's onboard navigator

As the first floor of a friend to answer the same, the general application of hand-held devices in land surveying, mountain climbing and other precise positioning when measuring the use of. Long standby time, three good performance. Easy to carry. A single charge can be used for a long time (depending on the machine). Although navigation, but the map is not detailed. At the same time, there is an opportunity to have latitude, latitude and other information.The car navigation is designed for users to drive out, in the field when not familiar with the road, ah, not familiar with the surrounding buildings, such as parking, hospitals, restaurants, gas stations. Used. Map details. But does not provide information such as latitude accuracy. No elevation.Look what you're doing. There is also a mobile phone navigation function.If you are purely for entertainment, then choose the phone.If you want to navigate in the car, select the vehicle navigation.If you are a very professional outdoor sports enthusiasts on the choice of handheld.

Q:Handheld GPS positioning, can be directly uploaded to the computer, and the computer has a scalable map to mark the upload point. The above system, now there are 20Such as the title, I want to achieve the final function: through the manual to a point, with a hand-held GPS locator will be recorded in the specific latitude and longitude, and sent to the network in real time, for my computer to mark these points on the map. If you can directly enter the site of some of the information, directly to the above is the bestIf you have the above equipment, please indicate the scientific name, and the specific application industry.Thanks.

Q:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,

If the area is measured, are almost. However, if the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.

Q:How the German born handheld GPS Mu meter, I want to buy?

The data acquisition function of scientific, simple and accurate measurement of area, display area and the "Mu", "price" area can be set automatically calculate the area of "price", fit the actual demand Chinese industry users on the data collection and usage, highlighting the professional quality.Is the highest cost-effective mid-range machine

Q:Handheld GPS locator measuring accuracy is about how many meters?

The handheld machine precision is generally divided into: centimeter decimeter level, 1 meters, 2 meters, 3 meters, 5 meters; the precision is higher, the higher the price. You can consult the Haida official website "mobile MGIS mall".
