- 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?
- 1. GPS is a geodetic instrument, with an accuracy of CM, generally for the millimeter,,Divided into (1) pure static type, such as the South Star of the North Star, the accuracy of mm, now the basic domestic,,(2) RTK, RTK can do is use, carrier phase measurement, the precision is cm level, RTK mobile station must have the control hand book, like television and remote similar, but now there are a lot of hand book can be used as handset2. The handset is generally rough field positioning equipment, navigation for mobile phone use, the general size, precision grade m, now can to about 20cm, and can be used for RTK mobile station use (need to access the base station) can reach cm level.Surveying and mapping qualification applications require geodetic measurement equipment, that is, 1.Now domestic GPS, such as the Haida, the south, China, etc. can be measured, not expensive
- Q: Handheld GPS buried in the soil there is a signal
- It depends on how deep you buried the darker the GPS signal, and must ensure that the GPS antenna upward, the above can not be covered with metal objects
- 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: 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: 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.
- You are very normal, the tablet computer and mobile phone antenna, not inside, the highest accuracy is about 10 meters, as ordinary navigation is good enough, to achieve centimeter level accuracy by GPS single is, that is to achieve the RTK measurement, is the application of professional measurement, now RTK or by the United States GPS satellite, not the United States GPS satellite as China Beidou mobile station and the base station is in need of mutual difference calculation to achieve accurate measurement. Now the single can receive SBAS signal, single precision up to 1-2 meters, the Northeast in some places to achieve sub meter level, which is the highest single precision can reach, is also used in field investigation using professional machine.
- 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,
- SOSO map is good, I use this.Kelid navigation is also good.
- Q: Handheld GPS and mobile phone GPS what is the difference?
- Different: antenna size, function, accuracy, protection level, and has been different in the application layer (handheld GPS support GPS compass navigation and map navigation and other more professional GPS applications);
- Q: Saying that we have a project in front of it is to do so, it is surprising that there are wood
- It is really unexpected, basically not, the accuracy is not enough!
- 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
