Many years ago, people relied on the sun, the moon and stars to find their way around. Later, the compass (指南针) was introduced. And now, we have satnav (卫星导航) systems to guide us. A satnav system uses groups of satellites to show the user’s location. They send information to a receiver, such as a smart phone, to show us where we are.
The earliest built satnav system is the Global Positioning System, which belongs to the US. Then there is Russia’s Global Navigation (导航) Satellite System, the European Union’s Galileo and China’s own satellite navigation system, BeiDou.
On October 14, 2017, an ARJ21-700 plane, which was the first domestically-produced jet (国产喷气式飞机) equipped with the BeiDou navigation system, successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced aboard, according to the Commercial Aircraft Corporation of China.
Since its introduction in 2000, the Beidou navigation system has seen increasing numbers of applications linked to everyday life, from shared bikes to farming.
When it comes to shared bikes, smart locks that support BeiDou chips offer more accurate positioning than others, making it easier to find a bike.
Farmers can use BeiDou-enabled tractors to plow (犁) the soil and use unmanned aircraft with BeiDou to sow seeds, which can improve efficiency and make better use of resources. BeiDou’s farming applications have spread from Heilongjiang province to Beijing, Liaoning, Shanxi, Hubei and other regions across China.
With its many uses, the Beidou navigation system is even playing a big role in the Belt and Road Initiative (一带一路). “To date, the BeiDou system has covered most parts of the Asia-Pacific region (地区), as well as countries along the Silk Road Economic Belt and the 21stCentury Maritime Silk Road” said Yang Changfeng, Chief designer of the BeiDou system.
Today, there are more than 20 BeiDou satellites above our heads, and China plans to launch even more this year to expand the BeiDou network to better serve the Belt and Road Initiative.
“As BeiDou expands its overseas reach, it will be increasingly popular in the logistics (物流) industry,” said Miao Qianjun, secretary-general of the navigation services association. “Ships, for example, can use it to position themselves while sailing across oceans to European countries, no longer limited to Southeast Asian regions in the near future.”

Nine-year-old Regina, from Scotland, has always loved taking photos. When she was just three, she picked up her father, Kevin’s camera, and asked him how it worked. But rather than just being a curious(好奇的) child or a girl with an inability to leave anything alone, Regina is in fact a professional wedding photographer.
“Regina became interested in photography at a very young age, ” her father, and fellow professional photographer, Kevin, tells Daily Mail Australia. “She first started asking questions about how to use my cameras.
Regina has never been on a training course,” He goes to explain that he has never forced his daughter to take photos like her dad does for his job. “I just answer questions when she asks them, and when she wants to do some shooting she can. Over the years she tagged along to quite a lot of shoots, so her skills just grew through experience.”
These skills reached the highest point on April 15 this year, when Regina shot over 400 photos at her first wedding. “She completely love it,” Kevin said. “She is quite a quiet girl, but when she has that camera in her hands she is super-confident, and had no problem dealing with people or setting up shots throughout the day. Regina’s next wedding is on July 1 and several of my other brides have called to ask if she can come along as they love her work. I honestly don’t have words to describe how proud I feel,” he concluded.
“In the past, Regina said a few times that she just wants to keep it as a hobby,” said Kevin. “But over the past few days, upon seeing some of the response her work has got and some of the nice messages she’s received from people all over the world, she has said she might like doing this when she’s older.”
