GPS Enhance the signal, regardless of the weather interference.

The so-called multi-system compatibility, take a like the Big Dipper we can receive the Big Dipper and the GPS signal of the two systems, does that mean  Get a GPS Beidou still able to navigate, this is a multi-system compatible with the concept.

In addition, a navigation enhancement, this somewhat professional enhance the integrity and accuracy, why should enhance briefly. Lane to keep cars judgment, the judgment of the lane, all requiring high accuracy and high integrity.

Did not open the car in Shenzhen, Beijing driving a car, or sit another car, take the main road in tricyclic, often heard in front of traffic lights to slow down, why there is this phenomenon, because its clearly announced that all ten meters, 10 meters this distance is not sufficient to separate the lane, and sometimes even the main road and side roads are inseparable from the middle of a buffer zone, only two or three meters wide, it must remind you, so prefer to believe them, not believe its not walking in the parking of the auxiliary on saw red.

This is what we so-called enhanced, the simplest way is to increase accuracy. There is also an integrity and reliability, these two relatively professional that the so-called integrity, to maintain the probability of this high-precision service, integrity and reliability.

Strategy, the three strategies of the State, an assessment, the assessment briefly, my side organized a science and technology group, the assessment of all seven modules of the main manufacturers, assessment of about 120,000 km, 11 provinces, municipalities, the test validation. After assessment, the Beidou GPS dual-mode module performance testing and tendering, and its basic performance close to the foreign mainstream commercial mainstream GPS module, the problem is the volume is too large.

Let 1 cm, length and width than he. In addition, in the power consumption is slightly larger, easy to handle in the car, armed with too much trouble, because the power twice, the car battery. Handheld on the battery is not convenient. Another receiver sensitivity is similar to the price of one hundred dollars the gap, we in front of an amount.

Our final results of the evaluation is available, this is the Big Dipper coordination meeting, Industry and leading reporting.

Differentiated services from our department in charge, and then until our scientific and technological development and reform transportation relevant departments are considering, it differentiated services, why should the differentiated services, the Big Dipper in order to industrialization, Main products: car dvd player and car dvd , are with good quality.not only rely on the support of the policy, the country's capital, how to do  Depend on the value, the price of a chip maker, think of a way down this terminal price, performance improvement, is an enterprise stem not a country and industry, performance improvement, we generated and GPS its comparative advantage, in addition to 9.6 million square km we can stop, less than 9.6 million square kilometers, through a coherent infrastructure within the road test of the city, this building, the Beidou superior in performance far superior to GPS performance.
