Editor's Note: the big feeds from today. Micro letter: today the Big Dipper, pay attention to big industry.
Today is the last day of the 70 anniversary of the parade off during anti-Japanese war, but I believe that our breasts were starting in the big parade in blood and a sense of pride still can't be dispersed. During all this was behind the success of the commemoration, is inseparable from the support of technology, the Big Dipper is also one of the.
The parade scene when compelling question: size of 12,000 people parade, hundreds of ways in which equipment is, to achieve the uniform? In addition to know the Big Dipper for parade training, play an important role in the parade but also what application is not to be found in the Big Dipper? Victorias Secret iPhone 6 Plus Cases
Security vehicle dispatch system
Before the parade, President, XI Jinping and his wife, Peng Liyuan, Duan gate square to greet leaders at the Convention, attended the commemoration of guests arriving by vehicle on time, in order, split-second. But this in fact refers to "guard command and dispatch system of vehicles" credit.
In 2013, the Nanjing linkage technology group Beidou navigation and related research units of the PLA signed a strategic cooperation agreement, developed a guard vehicle dispatch system based on Beidou, in 2014 by the Chinese people's armed police force concierge team selected as the National Security Council system.
Security headquarters for the General Assembly to adopt the system, Chinese and foreign leaders can know in real time the departure time and location. Command simply on the big screen in the dispatch center to open map, click a location, you can give directions to the fleet of mobile terminals and road traffic police, marked the next target.
May at any time inform the team adjust your speed through the system, ensure that the fleet of vehicles to the venue on time. If the team quickly, if necessary, more around a few blocks. If advances slowly, or you can cut at short notice, and arranged around the other teams withdraw. In this way, guests participate in activities in many countries, may, in accordance with procedure split-second.
Parade vehicles training evaluation system
Parade, more than 600 vehicles military vehicles formed a team, uniform passing Tiananmen Square: constant velocity error is within 0.3 seconds of time, apart from the error is within 10 cm. First use of high precision based on Beidou navigation positioning of parade vehicle training appraisal system plays an important role here.
This system's main equipment suppliers and concrete implementation of the project founder is Shanghai Sinan satellite navigation technology co., Ltd. Earlier this year, Sinan received a military parade command task, although in theory and driving test systems, but parade vehicle examination system of training scenario is much more complex. In addition to the system significantly increased the amount of data, and vehicle data transmission when communication interference problems to be solved.
Past parade vehicles training, coaches are often discovered through Visual and video playback problems, accuracy and efficiency is not high.
This time around, the Beidou system in team in training, real time display of the precise position and speed of every vehicle, provides the coordinates of the data error is less than 2 cm, velocity data error is less than 0.03 m/s, data errors less than 0.1 degree, roll the data error is less than 0.2 degrees.
Coaches can view the data to accurately identify problems and vehicles, and can guide the driver in real time in the vehicle direction and speed. With the help of Compass, parade around 70 minutes of traffic on early training team evaluation, more than 90 points in General. Victorias Secret iPhone 6+
"The Big Dipper" airborne command square foot equipment "big watch"
Use the Big Dipper to locate people through satellite positioning requests to the service system on the ground, ground positioning system using double-ball original understanding calculate the user's position and sends the user, which station you can find out the user's location. While using GPS users can know where and can't let people know their place, this advantage is confidentiality.
The second generation Beidou navigation system with GPS-like functionality at the same time, it still retained the position reporting function, the user can choose whether to disclose their location. This feature facilitates the military parade command.
Parade parade of 12,000 people, a total series of 50 (staircase). Each team by reading with Beidou navigation system, such as square foot some of the staff people are equipped with positioning watches, similar to a small compass Navigator. Locations are projected on the screens of all the teams, between teams and the teams, and geometric relationships between man and man can be very clear and intuitive reflection, so that commanders in front of the screen each team and individual position very clearly, truly Holy, winning thousands outside.
Here, the Beidou system has a GPS-like functionality at the same time, also has a unique reporting functionality, and provide convenience for military parade command.
Compass exact space time function review, the officers and men of the time consistency problem can be solved. If two planes to cross flying in the sky, is based on the pilot's skill, but also needs to control the precise time, the Big Dipper, ensures the unity of time.
Note: the people's Liberation Army Lieutenant General, former Chief of staff of the PLA general staff, Central Military Commission Vice-Chairman Zhang Zhen, comrades, died of illness on September 3, 2015 at 17 o'clock in Beijing, at the age of 101.
I have in the end to finally pay tribute to Lieutenant General Zhang Zhen, General of the founding of China!
