- Q:My friend is in use, the difference is not big, professional handset (smart or Magellan bulky, but 3 case), but the price is expensive, but can not call and map is very rotten, endurance of 10 hours (dry battery) the mobile phone also has all the time. Know friends say, I mainly in the suburbs! Thanks
- Two, different hardware configurationAs the field work environment is relatively poor, so waterproof, dustproof, shockproof for handheld GPS is very necessary. Handheld GPS on the market level of water is generally IPX7, and the continuous use of time is often more than 10 hours. Mobile phones are not so much demand. Handheld GPS function is relatively simple, and even most of the products are still grayscale display screen, multimedia features almost No.In the chip, there is not much difference between the GPS and GPS handheld mobile phone, mobile phone is commonly used in the Samsung 2440 chip and SIRF III receiving module on the handset is also very common, but in recent years MSTAR from Taiwan due to its advantages of cheap, very popular in the low-end handset.
- Q:Mobile GPS can replace professional handheld GPS
- No, the phone's GPS is used for navigation, professional handheld GPS is used for measurement. Navigation GPS cannot be used for measurement because of insufficient accuracy.
- Q:What do you need to test for GPS?
- 6 antenna type to give you a good positioning, GPS receiver requires at least 3 ~ 5 satellites are visible. If you are in a canyon or on both sides of the street, or in the dense jungle, you may not be able to contact with enough satellites, so that you can not locate or only two-dimensional coordinates. Also, if you're in a building inside, you may not be able to update your location, some GPS receivers have a separate antenna can be attached to the windshield, or built-in active antenna, or an external active antenna can be placed on the roof, the receiver which helps you get more satellite signals the. 7 other indicators to buy GPS equipment, according to the needs and use of the environment, size, weight, waterproof, shockproof, dustproof performance, high temperature resistance, power consumption and other indicators should be taken into account.
- 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.
- 10 meters.To the world in 2013 a total of four global satellite navigation system, in addition to the United States has been in the mature GPS system and commercial operation, the Beidou system, China the European Galileo system, the Russian GLONASS system are still under construction. "The Galileo satellite navigation project" was first conceived by the 30 satellite GPS network to compete with the United States, the beginning of the design proposed in 2008 formally put into operation, and later postponed to 2014, the entire system is only 4 satellites in orbit (as of 2012), in fact it is mainly used to further verify the relevant design and the working system of the system design, after the official start of Galileo satellite will launch. Formal networking satellites are being prepared. China satellite navigation system management office senior engineer Yang Qiangwen introduction, to 2012, the "system" in orbit satellites are also only verify satellite.
- Q:Handheld GPS positioning, can be directly uploaded to the computer, and the computer has a scalable map to mark the upload point. The above system, now there are 20Such as the title, I want to achieve the final function: through the manual to a point, with a hand-held GPS locator will be recorded in the specific latitude and longitude, and sent to the network in real time, for my computer to mark these points on the map. If you can directly enter the site of some of the information, directly to the above is the bestIf you have the above equipment, please indicate the scientific name, and the specific application industry.Thanks.
- The main function of Siwei Hin GPS map tag software1 support Google online (offline) hybrid satellite maps and general maps.2 support 1-18 level map arbitrary scaling, the left mouse button drag roaming.3 support the name of the query location, you can enter the location of the location after the location of the query.
- 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
- Application of GPS in Highway SurveyHighway routes are generally in a ribbon corridor. It is often used in the plane control measurement, which includes the form of wire, closed wire, wire and so on. For important structures such as bridges, bridges, tunnels, etc., but also arranged into triangular network, linear lock and other forms.
- Q:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,
- If the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.
- Q:Handheld GPS charge is not into electricity what is the reason
- Two, solutions:1, for other chargers, or data lines try, or clean the charging port.2, boot into recover mode advancsd advanced mode, select the wipe Battery, remove battery traces.
- Q:How to upgrade handheld navigator
- Recommend the use of mobile map navigation.Chasing the answerEasy upgrade.
- Q:How to use the handheld GPS whole watershed investigation
- The critical value is an object from a physical state to another physical state, a physical quantity to meet the conditions, which is equivalent to the stagnation point in Mathematics
