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 is the difference between industrial GPS handset and mobile navigation

I am a professional to do GPS, the difference between the professional handheld and mobile GPS is very understanding, here and your simple communication.1, GPS is the most important positioning accuracy and confidence. Professional handheld GPS chip used to stabilize the performance of some, the accuracy will be better, such as Garmin handheld high-end product positioning can be achieved within 3 meters, while the phone's GPS chip is different.2, both in the design and positioning of the crowd is very different. Professional GPS more focus on outdoor industry and users, the use of design idea is how to better outdoors, outdoor tourism including tourism exploration assistant very full function, and mobile phone GPS is a trend not only, what purpose.

Q:Mobile GPS can replace professional handheld GPS

Ziphah measured Mu instrument, a key measurement area, the use of simple, SV-118, with high precision imported GPS module and antenna, accurate measurement, the block walk in a circle to measure the size and graphics trajectory, 550 yuan, USB charging, large capacity lithium battery, black and white screen to see the clear day for outdoor use.

Q:My cell phone: HTC Hero 200Question type: Internet softwareMy work needs to locate, record, output, and input GPS coordinates. Track record measurement, coordinate transformation. So would you have a professional security software under the table, so go out with a mobile phone or a PAD, or N equipment back to survey the tired,

Taobao to enter the online shopping, mobile phone navigator on the line, I suggest you download the Careland navigation map, or tiger map

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

Effect of GPS navigation handheld as vehicle, as the vehicle with what map, the hand-held GPS is mainly used for point positioning, measuring area, high precision, good anti 3, my understanding is that

Q:Hand held GPS coordinate conversion method

Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.

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

Defects of conventional measurement methods:1, the specification of the length of the attached wire, the length of the wire and the length of the wire between the nodes have strict requirements, generally for high grade roads are required to meet the requirements of the first line. In this way, the length of the wire shall not be more than 10 km, or the length of the wire shall not exceed the length of the wire attached to the attachment of the wire length of 0.7 times. This requirement is generally difficult to achieve in the actual work, often appear super standardized operations.2, to collect the starting point for the general route of measurement and control is difficult to ensure the same measurement system, the measurement and measurement, often in the city of control points mixed together, the compatibility between systems, if the starting point is not compatible, is bound to affect the quality of measurement.3, serious damage to the national site, the impact of measurement operations. Due to the country's basic control points, mostly completed in 50s and 60s, after more than 30 years, some point due to the needs of economic construction is destroyed, and some people because of the lack of knowledge of human destruction. Route survey work in these areas, often in the 50 km above all can not find the wire control points. The quality of the route control survey is not guaranteed.4, ground visibility difficulties often affect the implementation of conventional measurement. The control points of the general route shall be located within 300 meters from the course. Due to visibility reasons, it is difficult to meet the conditions, even in a large range, and the dense shrub forest area, simply can not implement conventional control measure.

Q:How to use the handheld GPS whole watershed investigation

Therefore, it is an important method to solve the maximum value in physics by solving the maximum and minimum values of the physical quantity by the critical state.

Q:What qualifications should a normal GPS locator have?

You ask is handheld GPS, it is the manufacturer's qualification requirements or what. For example, business license, tax registration certificate, organization code certificate, vendor authorization, software copyright, precision test report, 3C certificate, ISO9001, industrial grade IP certificate and other relevant qualification certificates and documents

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".
