Beidou system starts service in Asia-Pacific
NANJING - China's domestically made Beidou navigation system has set up a network in Pakistan, the first in a foreign country, the company said Thursday.

Beidou was co-developed by China Great Wall Industry Corporation and the Beijing UniStrong Science& Technology Co., Ltd. The first stage of Pakistan's geographic positioning network has been finished, Shen Jun, chief scientist of UniStrong, said at the annual China Satellite Navigation Conference in Nanjing.

The network includes five base stations and one processing center, covering Karachi. It can provide positioning with a precision of 2 centimeters, while the precision can reach 5 millimeters after post processing, and can help in urban planning, surveying and mapping, environmental supervision, disaster relief, traffic monitoring and other fields.

Shen Jun said the second stage of the network will cover the whole of Pakistan and be the first national high precision Beidou navigation network abroad.
