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:Handheld GPS and mobile phone GPS what is the difference?: The same: GPS main chip may be the same; can complete the GPS positioning;

Q:GPS Mu meter which brand is good, handheld high-precision land area measuring instrument: A German born mu can also recommend a good precision measuring instrument.

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. Set of SIBAO products awarded the Beijing independent innovation product identification certificate, satellite navigation and Engineering Excellence Award and other professional awards. At the time, location, navigation and other comprehensive applications, Unistrong successful implementation of hundreds of large projects, services in many national key projects, won the national honor.MagellanGarmin

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:How do I still stay in the GPS navigation, GPS monitoring of the primary idea? FiveBusiness services, thank you!Future business services: Mainly for the ship, automobile, aircraft and other moving objects positioning navigation. For example:1 ocean navigation and incoming water diversion2 aircraft route guidance and approach landing3 vehicle autonomous navigation4 ground vehicle tracking and urban intelligent traffic management5 emergency rescue

Q:What qualifications should a normal GPS locator have?: Look at his company's business license is what's on the line, if the manufacturer has the most basic 3C proved, and some such as system certification or proof of what the explosion proof CEPREI

Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.: Look at the maximum accuracy of GPSIf the difference accuracy can reach 1cm you can connect CORS single base station and other network RTK way to achieve the corresponding accuracy

Q:How to upgrade handheld navigator: Some 4S shop can;Read the instructions, there are generally USB mouth, then you can upgrade the computer practice;There is a memory card, then you can remove the plug on the computer upgrade;Or get the computer city to see it.

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.
