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: Jia Ming etre20 handheld GPS good
The new generation of the eTrex series is the first generation of user level receivers that can track both GPS and GLONASS satellites. GLONASS global navigation satellite system developed by Russian Federation, fully put into use. When using the GLONASS satellite, the average time for the receiver to lock the target is about 20% faster than GPS. And, when using both GPS and GLONASS, the receiver has the ability to lock more than 24 satellites as compared to GPS alone.
Q: Verify the accuracy of the GPS device to buy back, the way is to use Android under the'gps state 'software, to test the accuracy of real-time single point positioning.1 with two sets of the same Android Tablet Computer (custom machine, type of bad) in the same position for receiving, find that the accuracy is the same (software, are 1-2 meters), but the position would be poor 10 meters or more. It's in the same place.The 2 one is the Android tablet computer, a mobile phone is HTC G10, also received together in the same position, find that the accuracy is not the same as (the latter 20 meters or so), but also may be about 10 meters position difference.The accuracy of this GPS device can reach 1-2 meters, while the same location in real-time single point positioning error of 10 meters, a reasonable explanation.
Oh the single point positioning accuracy is about 10 meters, but also have a great relationship with the environment around you, if in the city, the accuracy of twenty meters are possible, if the open place, outside. Ten meters should not be a problem. Whether you use a professional measurement RTK or ordinary navigation handheld machine, single point positioning accuracy can reach 1-2 meters of the machine I is not met, if you see where I wish to share with me, thank you. Can only say that the use of professional measurement RTK will certainly be higher than the navigation accuracy of GPS single point oh
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.
