China's coastal provinces will deploy unmanned aircraft to carry out marine surveillance, with trial operations expected to wrap up successfully by the end of this month. Maritime experts said the new technology will help monitor pollution and protect resources along the coast.
The State Oceanic Administration (SOA) announced Monday that 11 coastal provinces will each set up a strategic airbase for unmanned aerial vehicles, or UAVs. Each airbase will be equipped with at least one drone for maritime surveillance, the maritime authority said.
It is a first for China's maritime surveillance, said Yu Qingsong, the coastal division director of the SOA.
"Coastal development activities are increasingly important for China's economic growth, and the demand for sophisticated maritime surveillance has grown," Yu said.
"We adopted satellite and wave estimation technologies in the early 1990s. The new UAVs will help step up our monitoring efforts." He added the UAVs can monitor coastal activity, including land reclamation and off-shore drilling.
Real-time data fed from UAVs is more accurate. UAVs can also be deployed in adverse weather conditions and cover much larger areas than wave stimulation machines, Yu said.
The Liaoning provincial marine patrol center launched the pilot UAV program late last year, mainly to monitor the coastal areas of Dalian, Jinzhou and Panjin, covering an area of 980 square kilometers.
Jiangsu Province also launched its first UAV monitoring test on January 8 this year. China has the world's 11th longest coastline of 14,500 kilometers, according to the SOA.
Scientists can control the UAVs remotely and direct them to designated areas for data collection.
The photos and data, including temperatures and water levels, will then be observed and analyzed at laboratories to determine if there has been any illegal sand dredging or land reclamation activities along the coast.
Lin Minsen, a professor at the Shanghai Maritime University who specializes in coastal surveillance technology, told the Global Times that UAVs had been used in China's mapping in previous decades.
"The country's drone technology is very mature and the high definition photographs recorded from these UAVs are valuable data for maritime monitoring," he said.
The SOA will hold a series of evaluation meetings of the UAV test in Jiangsu by the end of August and the airbases in the 11 provinces will be set up early next year, it said.
