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
Three, the map of the differenceIn terms of the difference between the two maps is relatively large, most of the hand-held machine using contour map, the city is only as a secondary auxiliary. The mobile map is just the opposite, very detailed description of the city streets.Refer toThere is no road for GPS routing calculation. Popular said, handheld GPS to do is to draw a straight line to the destination, to determine their own inflection point. Handheld GPS will tell you to the destination: distance, course, yaw distance and other information (a lot of parameters, you can choose to display). In addition, handheld GPS also has to add a new landmark, through the software to draw their own waypoints, the average position of the measurement function, and even can measure the height and temperature, highlighting the degree of professionalism of its application.Cell phone navigation is very different from the former. GPS will be in accordance with the routing algorithm to calculate the nearest path, the premise is to have a detailed street map. GPS will tell you the right to turn right at the intersection. Mobile GPS can also search the starting point near the point of interest information, and can calculate the fastest path to reach the land.
Q:I bought the way k20s, this handheld GPS how
Ordinary hand-held GPS is 3-5 meter accuracy, high accuracy can be achieved unless buy submeter ordinary user, if you can.

Q:What is the difference between the phone's GPS and professional handheld GPS features and differences?
If you travel enthusiasts so you still recommend buying the handheld bar dry batteries can be replaced immediately if it is built in deep mountains and forests where you go oh for charging software installation, you can go to the forum to see the relevant system is very simple and the most important point is that basically all the navigation software has cracked the free version allows you to use it here and I hope to help you
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.
