- 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: Handheld GPS locator measuring accuracy is about how many meters?
- The higher the accuracy, the higher the price. You can consult the Haida official website mobile MGIS mall
- 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?
- Q: I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
- If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy
- Q: Handheld GPS brand rankings
- SIBAOIn the GNSS coordinate precision and attributes, "SIBAO" has a professional GPS handset, GIS i-PPP GIS, a mobile data collector, GIS, high precision GIS, high precision measurement of RTK complete product structure, to form a comprehensive solution to the spatial information industry scheme.
- 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: 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: Fuxin coordinates with the mapping of the seven parameters are what ah there is no professional knowledge to tell my brother I need to fill the gps... Thanks.
- XYZ offset, XYZ twist, 6, plus a scaling factor.Seven parameters have to be calculated, or from the local surveying and mapping departments to.
- Q: The navigation module it is "selph" three generation? Another one I mainly use it to measure the land area, easy to use, the error is not big?I want to buy Magellan 500 do not know whether it is good to use
- Professional handheld GPS only Magellan and set SIBAO
- Q: How to hand GPS eTrex H data to the computer
- You have a data cable, the computer installed on the MapSource software, connect the computer and handheld GPS can transfer data!!!"Shaanxi skmax navigation information Limited" GARMIN proxy (GARMIN official website can be found), contact (Xiao Hou) the hope can help to you, if you do not understand what we see on the Internet, may at any time, contact us
