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.
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.
Design ideas and the use of different objectsThe handheld is designed for military, mapping, mining, agriculture, outdoor sports (hiking, hiking, orienteering, cycling, water sports, paragliding, etc.).Cell phone navigation is designed to drive a car in the city, built-in interest points are mostly concentrated in the city.
Professional GPS is mainly used for acquisition, is not used for navigation; of course, some professional GPS can install third party software, the accuracy is higher than the phone, this is positive;Mobile navigation is only used for navigation, navigation, path analysis and navigation functions, not the acquisition of maps of the instrument.
I am a professional to do GPS, the difference between the professional handheld and mobile GPS is very understanding, here and your simple communication.1, GPS is the most important positioning accuracy and confidence. Professional handheld GPS chip used to stabilize the performance of some, the accuracy will be better, such as Garmin handheld high-end product positioning can be achieved within 3 meters, while the phone's GPS chip is different.2, both in the design and positioning of the crowd is very different. Professional GPS more focus on outdoor industry and users, the use of design idea is how to better outdoors, outdoor tourism including tourism exploration assistant very full function, and mobile phone GPS is a trend not only, what purpose.3, professional handheld machine with industrial design. 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.4, different screen design. If you look carefully, you can see in the outdoor light, mobile phone can not see the contents of the screen, while the professional handset is not the same, can see clearly in bright light, does not affect the work of foreign trade operations.5, strong battery life, is a major feature of professional GPS, Garmin handset General of dry batteries can be used more than ten hours, while the mobile phone GPS on GPS also can use a few hours, if you open the GPS in general about 3 hours will be over.6, supporting different software. Professional GPS handheld opportunities related to the PC end of the data processing software, this software can achieve the acquisition of data processing, as well as the application of data collection. The phone GPS can only navigation, and navigation is only a small part of the GPS function.I simply say these, this is my personal summary of the difference, if you have what is not clear can exchange. Want to help you.
