The Future Of GPS Mobile Location

< p > talking about GPS, the first thing you think of is driving navigation. This is a fact, but it is also a helplessness of GPS technology at present.

As you may recall, in the past 07 years, the entire mobile phone industry almost identified GPS as a new killer application on mobile phones. The items of GPS phones are everywhere, but the result is no one pays. In 07 or 08 years, GPS's performance on mobile phones has always been poor. The impression left on people is only three words with poor experience, and the dismal market performance can only be described by "no one wants" three words.

This made people feel very pessimistic about LBS itself, and even concluded that GPS is just a wrong judgement on the niche market with attractive cars.

In fact, the location and movement characteristics of GPS are very suitable for handheld devices. The LBS (location based service) that can be realized by GPS is able to jump out of the range of < a href= "http://www.91se91.com/news/index_s.asp > vehicle navigation < /a > and has a wide variety of applications. In the future, it has the opportunity to bring the market space far exceeding the total number of navigation equipment by mobile phone carrier.

So where is the problem? How far is GPS from the spring? < /p >

< p > remember the days when Google Earth was released, I know that many people around me have been searching all night for places that I have visited or yearned for very much, remembering their footprints or longing for their imaginary destinations.

When the Google Earth launch location is uploaded, how many people share or view these photos?

When Google Maps provides location services based on base stations and GPS on handheld devices, many of my friends around me have taken it as their most frequently used function.

The application of Google is not to be evaluated here, but it can be seen that because of these software, the application of GPS has begun to jump out of the category of vehicle navigation, and really has the opportunity to popularize on personal portable terminals.

A good application experience is the key to making the GPS such a huge potential become the standard of mobile phone, and the appropriate hardware scheme is the carrier of good experience.

Now we will analyze the past and present of GPS in China's mobile phone market from these two aspects: < /p >

< p > experience: what kind of GPS application and experience is needed in the market? < /p >

< p > if you let everyone vote to choose what is the worst in the GPS application experience, I would like to search the stars slowly or even half a day to find the star must be ranked first.

I have had many experiences like this before, when I was nowhere else in town, when I could not find the way, I took out my cell phone to turn on the GPS software. As a result, 30 seconds had not been positioned in the past, which made me feel irritable, and 1 minutes or more still had no location, so I could only press the torch phone to find other ways.

The application scenario of GPS often first determines its position and then performs other functions. If this first step is very slow, the death penalty for this application is pronounced.

This is precisely the positioning speed, which has greatly divided the GPS program.

Here we have to mention AGPS technology, AGPS can shorten the positioning time greatly, and really bring about an essential improvement to the GPS experience.

To make it clear, there are also some manufacturers who claim to support AGPS, but this is only a broad term.

The introduction of AGPS initially refers to the way to pmit auxiliary information combined with the network of operators.

Later, due to market competition, some manufacturers also confused the method of downloading synthetic ephemeris files into AGPS.

The method of downloading synthetic ephemeris files is because the ephemeris files are synthesized, so there is an effective period limit, usually 3-7 days. The longer the first time, the worse the accuracy.

What we see now is that if there is a so-called fast GPS app that has been downloaded ephemeris, it belongs to the pseudo AGPS. This method is helpful but limited and has many limitations to speed up the search.

The key to distinguish between the two is to see the protocols it supports, such as OMA SUPL1.0 or < /p >.

< p > {page_break} < /p >

< p > RRLP, RRC, etc. These are combined with the network of operators, that is, the real meaning of AGPS.

The real AGPS is when the GPS port is opened, it first obtains the accurate satellite information according to the current base station data, first to the network server (set up by the professional manufacturer and the operator), while the GPS system directly contacts the correct satellite according to the information obtained, and does not have to search in 33 randomly. Therefore, the positioning time is greatly shortened and the power consumption is also very low (the following table).

According to the measured data, the GPS system under this way can accomplish the location within 20 seconds steadily.

Under such data, the application experience of GPS will be very good, and it can really open up.

< p > if GPS positioning time can be solved, GPS's second important experience is to have a large number of applications. As I said earlier, GPS is not only an application of navigation software.

Google Maps has made a good start. We can see that a large number of LBS applications are springing up on the open intelligent operating system. The increasingly enriching of GPS applications is a sign of the true popularity of GPS.

< /p >

< p > another experience is also very important. The combination of Internet and a is the direction of application development of < a href= > LBS < /a > data online can effectively solve the problem of information timeliness and local large capacity redundant storage, and no matter how rich and attractive applications can be derived from LBS application, no one can speak clearly.

For example, Google map recently launched a function Google Latitude on the phone, allowing you to check the location and status of your friends in real time via Google Maps on your cell phone, and share your information with them.

You can also limit or control the degree of detail shared with each friend. You can also change your status messages, photos and add phone numbers at any time, so that your friends can call or send SMS directly from the Google map.

< p > hardware scheme: what is a mobile phone carrier suitable for GPS application experience? < /p >

< p > we might as well take a look at the system configuration of the low-end Feature Phone almost all over the last two years: the ARM7 100 trillion master processor with all the software running burden, such as protocol stack and MMI, the unstable data access capability, the poor Flash and RAM surplus space, the cost GPS scheme and the antenna selection, and the closed operating system.

Under such a big background, developing a mobile phone with GPS function first needs to choose the appropriate GPS hardware scheme. However, restricted by the technical ability, it will basically choose GPS module, which will make the cost obviously higher than that of COB (Chip on board), so it can only save money on the day line.

Unfortunately, such a combination is neither good at performance nor cost.

In terms of software, any application needs to be customized for such a configuration. The workload is not big enough to say that the content is single, nor is it left to the third party GPS's excellent software development space.

Although many people have done many attempts, but how can such a carrier bring a good experience to users? No good experience, even if the cost is good, no one will pay the bill. Besides, the cost is not good, so the failure to popularize is doomed.

< /p >

At the same time, the international first-line brands have also joined the GPS function in the mobile phone. Nokia, Samsung, HTC and RIM are all equipped with standard in almost one of their own series. Nokia has cut into the map service market through the merger and acquisition professional company. It can be seen that these big factories have similar judgments about the popularity of GPS. P

These machines have some common characteristics: excellent GPS device selection + powerful processor + intelligent open operation system.

This configuration provides enough operational power for related applications, and can also bring more and better application experience through the expansion of third party applications.

< /p >

"P > inside and outside contrast, we are afraid that it is very easy to get a reason why a href=" http://www.91se91.com/news/index_x.asp "> GPS < /a" in the first two years.

Of course, some people will say that the cost of those international brands is so high that they simply can not adapt to the Chinese market.

But aren't there any domestic manufacturers pushing high performance low-cost intelligent platform on the market? {page_break} < /p >

"P > domestic smart phone solution provider Hass recently announced a strategic cooperation plan with SirF, which fully and completely provides AGPS technology in its K3 intelligent machine plan. The technology can be fully covered by the whole world (OMA SUPL AGPS service provided by SirF can cover mainstream operators such as China Mobile and other overseas Orange).

In the near future, SirF has also worked with Hass to create the world's first SUPL AGPS solution based on CDMA network creatively with its own special technology, and released it to the customer with the CDMA intelligent machine plan of Hass K3.

In this way, it is no longer a problem for domestic manufacturers to get the complete AGPS smart phone scheme, and the technical bottleneck is no longer there.

< /p >

< p > here, let's make a small summary: < /p >

< p > 1. end-users have a wide range of original needs for GPS Technology (LBS); < /p >

< p > 2. good GPS application experience has begun to appear and is developing rapidly on various open operating system platforms; < /p >

< p > 3. the appropriate system platform that can carry these application experiences has also appeared: high performance processor +AGPS scheme + intelligent system < /p >

< p > we can see that there is a demand, a plan and a platform, and the development of GPS on mobile phones is all the same. What kind of east wind do we still owe? The east wind is the general trend of China's mobile phone market. It should be certain that GPS applications can not really develop on Feature Phone. So what is the development trend of smartphone in China's mobile phone market? We have heard many times this year that the year 2009 is the first year of China's smart phone, and the actual market situation is also supporting this view. A large number of design companies and brand manufacturers have started the development and design of smart phones. We believe that in the second half of this year, a large number of smart phones will be released to market.

GPS, as one of the most valuable applications on smart phones, will definitely match the great development of smart phones.

So, the spring of smart phones is coming, can spring be far away from GPS? < /p >
