- 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
- If you are a GPS base station location and measurement of road staff recommend that you use the professional version of the GPS version of the great error because you said is also a way of positioning is not accurate the coordinate system should also use professional equipment and operating personnel want to help you
- Q: How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
- Three parameter test DX, DY, DZ, DA, DF after the conversion parameters of the five, must be prompted to enter the handheld GPS, while the input area of the central meridian longitude. E on behalf of the east longitude, projection ratio of 1, the deviation of things to the north and south of the deviation of 0, and set the unit for M. Enter these parameters, should be taken to the field test, check whether these five parameters are correct. The method is selected, vision, GPS receiving signal strength of the feature points in the field (such as linear object intersections, independent features, etc.) is the best stone control points were measured and compared with theory and find out the coordinates of these points. If the results of the comparison exceed the nominal accuracy of the instrument, the conversion parameters or the problems that should be found should be recalculated.
- 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..
- Q: Can a handheld navigator connect a cell phone? Thank you
- Now basically use the phoneEasy update and operation
- Q: What is the difference between professional GPS handsets and mobile navigation?
- First of all, if used outdoors, then fell, and so on are likely to water, and this thing is also very expensive, so the opportunity to have a high professional anti shock waterproof performance. You can see the Challenger I tour the next 600, three well plates.
- 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: 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.
- Three translation parameters Delta X, Delta Y, Delta Z, three rotation parameter w X, Omega Y, Omega Z and a zoom M, these parameters need to be calculated in a fixed point under different ellipsoid!
- Q: How to upgrade handheld navigator
- Recommend the use of mobile map navigation.Chasing the answerEasy upgrade.
- 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: What is the difference between professional navigation and professional GPS navigator
- 1 high precision, good signal.Now GPS hardware precision is about 10 meters, the difference should be small. The accuracy of the practical application is also affected by the electronic map software. Signal does have good or bad, mainly in the fast positioning is not fast, stable, etc..2 long standby time, voice prompt.Standby time mainly to consider two factors. First, the battery capacity is large, two is the best battery is replaceable. PDA class GPS and vehicle navigation generally have voice prompts. This voice prompt is realized by navigation software.
