Beidou Navigation System to replace GPS?
Yang Yuanxi, member of the national committee of CPPCC and academician of Chinesee Academy of Sciences recently said in an interview during the two conferences (NPC and CPPCC) that China now has already successfully launched four Beidou navigation satellites for test and 16 Beidou navigation satellites, which marks the goal of constructing networks in the Beidou navigation area been achieved smoothly.
Speaking of satellite navigation system, most people will think of GPS (global positioning system). Indeed, American GPS technology has already monopolized over 95% civilian use navigation software. However, when we speak of Beidou navigation system, most people will fell at a loss. Is it self-developed by China? Is it better than GPS? All these questions come out.
"People don't know Beidou navigation system is mostly due to its application in the areas of military or other professional fields, with no close connection with ordinary people's lives. Yet, with Beidou navigation system to be applied in the residential areas, Beidou navigation industry will face a dramatic growth in the future," said Hu Guozheng, president of Hengda Electronics. He predicted excitedly, "By 2020, China's Beidou Navigation System might replace GPS, which makes it quit China."
There is a reason why Hu Guozheng is so confident at Beidou . Ministry of Transport issued " on accelerating the " notice of Implementation of monitoring and management services during transportation demonstration project " on 2012 December 31th, 2012.
According to the paper of Ministry of Transport , China will make experiments in Jiangsu, Anhui, Hebei, Shaanxi, Shandong, Hunan, Ningxia, Guizhou, Tianjin and other nine provinces and municipalities as well as the Pearl River Delta Force " Two tourism bus one dangerous " ( tourism charter , buses , dangerous goods transport vehicles ) vehicles with dual-mode Beidou navigation device in the 2014-2015 and subsequently across the country .
Prior to this, the Beidou is made for defense and professional fields , Nation develop a navigation system for national security , so they can hold the key to their home . The above "Notice" also published a national strategy to a further upgraded navigation of BDS.
" The Department of Transportation 's " notice " means the further opening of the Beidou navigation in civilian areas , and this is the opportunity ." Hu Guozheng told reporters that the company will focus on the layout of the nine provinces , plans to invest 200 million yuan , set up five information processing center in the east, north southern, central and western, as well as through the inspection in 15 major cities. And to develop more market channels, dominate the market. "Our goal is to obtain 80 % to 90 % market share in the next two years." But he also admits that with the introduction of the encourage policy , more companies have joined the competition, Beidou civilian navigation will likely become a hit areas. He said that his company currently has integrated several coperation, everything is ready to go.
Technique stronger than GPS?
The first open field , meaning Beidou navigation is going to be usd in personal mobile navigation, personal car navigation. However, relatively few people know Beidou navigation. What advantage does Beidou navigation technology carry tcompared to GPS? Can It really beat GPS ? Nowadays" Two one" were forced to install Beidou navigation, but for individual users and mobile navigation software side, would they be willing to choose to use Beidou navigation?
AS public opinion, Chinese self-developed navigation system is out of reach, but in fact the Beidou navigation technology has been contained after nearly 20 technology has been very mature since the 1990s.
From 2000, China is the third has its own satellite navigation system that earlier than the Europeans, after the United States, Russia. With Russia's GLONASS, EU's Galileo system, U.S. GPS global to share satellite navigation system , saying the world's four major satellite navigation system.
BD II system was officially approved on August 31, 2004, providing commissioning services since December 27th, 2011. Up to now, the Beidou satellite navigation system has launched four rockets and 6 satellite, and successfully launched 16 satellites covering the entire Asia-Pacific region while expected to cover global in 2020. .
In Hu Guozheng opinion, BD only thas he disadvantage of current coverage in Asia, in other respects, it is stronger than GPS. First, the Beidou navigation support real-time navigation , while GPS is not , GPS occasional updates will be easier in misleading the owners , this is never happened in the Beidou navigation. On the other hand , the clarity of Beidou navigation can be accurate to one meter while GPS need 10 meters. It is worth mentioning that the Beidou navigation has a two-way communication function , you can achieve a dialogue between the one driver and another driver . " It can be said that the Beidou navigation is a product contains mobile navigation, micro letters, tachograph , alarm system ."
