1 Do not use one or two, or a day or two to decide good or bad the GPS receiver – the satellite state as the sky is different every day, perhaps the same place, good morning reception, but can not good at night, may be also several days the positioning situation is not good.
2. GPS positioning can not be 100%, but do not believe the indoor positioning, unlike the mobile phone broadcasting, anywhere can receive the signal, a lot of things will affect the GPS reception, including Sky satellite distribution, buildings, viaducts, waves, leaves , lattice thermal paper, it will affect things too much, in general, from the GPS location to the point of view, can see the sky area is to receive GPS signal area.
3.GPS signal strength table, insufficient to buy a GPS reference – you buy a GPS, only to see the electronic map in the reception tables, the former may be quite accurate, but now the GPS, to allow the recipient to see the table it look good, so there are false signals, or signals, and so the simulation, the recipient table is indeed very beautiful, but perhaps positioning allowed, not even display correctly does not necessarily.
4 Comparison of GPS is good or bad, must be the same time and more – a lot of people buy a new GPS, will say, I had better use that kind of thing, but say not seen is correct, since the use of a different time and place, the final result is much worse, and must be long-term use, or the same time and can feel the difference between two kinds of GPS.
5 Buy GPS, do not need to brand for the purchase of options, but you can choose to use the chip inside. Basically, a lot of GPS manufacturers, vendor selection is only considered after-sales service only, not necessarily the best manufacturers on the recipient, in general, the same chip, GPS, different vendors to do, the effect will not be much difference, so choose GPS do not choose the brand, you can select the GPS receiver chip.
6. There is no indoor positioning GPS, essentially no signal is no signal indoors, a real indoor positioning, from coldstart start indoors, but you can locate, is the real indoor positioning, but basically there is no indoor positioning that sense, because I would not at home navigation.
7 Bluetooth GPS, CFGPS, or GPSmouse? – Generally, this is a matter of debate, the use of Bluetooth or cf, will not have to worry about GPSorpda electrical problems at any time, and expensive, but you can navigate anywhere, using GPSmouse economic affordable reception and good, do not worry about the power problem, but cable problems.
8. Positioning allowed, not necessarily the fault of the GPS. Basically, positioning errors in less than 20 meters, are considered a good cheap GPS receivers, the other, GPS location is not very accurate on the road, probably due to many possible reception and cause the error, map data may be a problem, there may be road very wide, so it looks like stable offset GPS road, with a long time you know the problem is the GPS or map.
10 Using GPS, do not receive communication costs – although we all know, but still it was always thought to the other monthly fees.
11. If the GPS is the first time a new buy, or already coldstart state, go to open the car positioned at the point – so to locate the faster, and less likely to have some strange phenomenon, if coldstart state directly on the road, even if the signals are strong, but may be to the destination can not locate Oh!! This is important, after positioning, and then into the car, the recipient will see the car relatively poor, while Single GPS uses the longer, satellite data can be stored longer, if the long-term need, such as a ~ two weeks, GPS may be restored to coldstart state.
These are new to satellite navigation for you, hope to have them prepared, they are less likely to feel bad use of satellite navigation, and basically, as long as the destination, the satellite navigation for you is a good thing to use a As there is no more time-saving, relatively short distance there are not too demanding, and essentially to a strange place, as long as smoothly to the ground like, maybe there will be some ironic distance in the planning and multi- Some way to go, but over time, you will understand the characteristics of the existing satellite navigation, will not be so unhappy with them, of course, the map makers still to be done, but I hope we can give proper incentives to firms to buy genuine is the best support .

Apple promises to change the tracking routines – IOS update comes. In a press release Apple admits that they have been too reluctant to inform their customers and promises to change security procedures. Storm around Apple and privacy It has stormed around Apple’s use of IOS to log the users’ location. In essence, takes Apple to the criticism and promised to make changes, but denies that they are using GPS to acquire location-data, or that they have access to location-history. New feature in the map application At the same time the company was forced to reveal one of the reasons that they log location: they will launch an improved traffic service. No date for the launch of this service, however, were not given nor details, but it is several years away. Here’s Apple’s explanation Over the coming weeks, Apple to launch an IOS patch that reduces the collection of data, stop the backup of this and clears the storage when “Location Services” is denied. These are important points to Apple’s explanation regarding the collection of location data: * Apple is not included on the iPhone is. The company says they’ve never done it, nor that they are going to do it in the future. * Apple says it only logs a database of WiFi points and antenna towers like IOS product is in contact with and it can often be talking about long distances between the IOS device, and these points. * In the log file, Apple may see anonymous data about which mobile phones are, but not as accurate as if they had …
