Russia and China have signed a cooperation agreement on satellite navigation, a Russian Space Agency spokesperson told RIA Novosti on Tuesday.
Roscosmos chief Igor Komarov met with Xu Dazhe, the leader of China’s National Space Administration, on an official visit in Beijing.
“The first provision to set up a committee and a protocol were signed during the first working session. Igor Komarov and Xu Dazhe discussed issues of bilateral cooperation in the field of electronic components for rocket construction and building rocket engines,” the spokesperson said.
A Russian-Chinese committee on satellite navigation was established in October 2014 at the meeting between Russia’s Deputy Prime Minister Dmitry Rogozin and his Chinese counterpart, Wang Yang.
In November, China North Industries Corporation (NORINCO) and the Russian GLONASS nonprofit partnership agreed to establish a joint venture to promote worldwide services based on GLONASS and BeiDou.
Russia and China also recently completed joint reconnaissance for the placement of GLONASS differential correction and monitoring stations in the Chinese cities of Urumqi and Changchun. Each country is expected to accommodate three such facilities.
