- 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:Handheld GPS navigation is what? Where to buy handheld GPS navigation, how to select GPS navigation?
- Handheld GPS navigator, also known as portable navigator, but also divided into 2 kinds, one is the ordinary PND navigator, you can go to Zhongguancun, the major appliance stores to buy, and the other is the mobile navigation, GPS smart phone is installed in the GPS navigation software can be,The navigator is composed of 2 parts: hardware and navigation software. The navigator on the market is about RMB 600. The brand of Kelid navigation software is usedGPS is a portable handheld navigation navigation products, the market is now very much, most car navigation can be used, the Gps signal is still free to receive satellite signals in the United States, you only need to charge it, map to the sellers in general can be upgraded.
- Q:Mobile GPS can replace professional handheld GPS
- Ziphah measured Mu instrument, a key measurement area, the use of simple, SV-118, with high precision imported GPS module and antenna, accurate measurement, the block walk in a circle to measure the size and graphics trajectory, 550 yuan, USB charging, large capacity lithium battery, black and white screen to see the clear day for outdoor use.
- Q:What do you need to test for GPS?
- As a high-tech product, GPS has a very complex technical parameters. However, as people's living standards improved rapidly, more and more ordinary people began to pay attention to the positioning and navigation tools originated from the military. Because the convenience it brings is unprecedented. In order to let everyone out of all the technical parameters of GPS receiver, no longer confused at the time of purchase, the author selected six of the most important technical indicators, one by one to explain to you. 1 parallel channels on the market most of the GPS receiver is a 8 channel, 12 channel, the 16 channel, which allows them to continuously track the information of each satellite. Some GPS devices only have 2 to 5 parallel channel receiving satellite signals, because the average of 8 satellites are visible, which means that the GPS receiver must visit each of the satellites in order to obtain information about each satellite. All of our products are in Shenzhen channel 16 channel, multi-channel parallel GPS receiver, including the advantages of rapid cold start and initialization of satellite information, but also in the forest area can have a better reception. General 12 channel receiver does not require an external antenna, unless you are in a bad environment conditions such as closed space, such as the cabin, the car. 2 the sensitivity of the GPS satellite signal to the ground has been very weak, as well as ground wireless communication clutter interference. The lowest traceable signal strength of the GPS receiver determines how much useful signal is received. A GPS receiver with a lower minimum tracking signal strength has a higher sensitivity, and can receive more available satellites under bad conditions
- Q:GPS handheld function to measure it?
- If the construction survey is certainly not the case, the control measurement is possible
- Q:Hand held GPS coordinate conversion method
- Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.
- 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
- For long tunnels, the conventional measurement of large bridges has the following limitations:1, long tunnels, bridges and other structures generally require the measurement level of four or more. With conventional measurement methods, often adopt the measure to increase the number of methods to extend the observation time, time consumption and labor consumption to try to improve the accuracy of.2, the long tunnel and bridge for the complex terrain region difficult, conventional control measure for visibility and network shape, often cut down the workload is quite large, so the measurement of the cost of a large, hard work.Link control network of high precision 3, long tunnel and bridge and low precision and route network, although with adjustment methods can be overcome, but because of the terrain conditions are difficult, the measurement workload to its connection, and is not too easy. In practical work, the control of the structure and the measurement of the route are often out of touch.
- 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
- 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:I am ready to go to the field to go to college, but I do not know how to buy a handheld GPS, I hope you recommend. The most important thing is easy to carry.
- Oh, if you go abroad to go to college, buy a map you can, no need to buy, if you want to buy, you have to look at what price, what configuration, entry-level like upstairs said, a few hundred dollars can buy one, but is relatively old models. No maps. If you want to have a map to your point, there are Yiliangqianliangsanqian. Recommended Garmin 60csx, Magellan explorer, Hua Cai Lu N400 can be.
