China launches two BeiDou-3 navigation satellites into space

China has successfully launched two BeiDou-3 satellites to provide navigation and positioning services to countries along Belt and Road initiative (BRI) by the end of 2018.

The two satellites were designated as BeiDou-3 M7 and BeiDou-3 M8 (26th and 27th satellites) in BeiDou Navigation Satellite System (BDS).

Key Facts

These two satellites were launched on board of Long March-3B carrier rocket from Xichang Satellite Launch Centre in southwestern province of Sichuan. This was first launch of the BeiDou satellites in 2018. China is plannig to send 18 BeiDou-3 satellites into space in 2018.

These two satellites were based on newly-developed dedicated satellite bus and weigh about 1 metric ton each. Both spacecraft had two deployable solar arrays and are designed to be operational for about 12 years. These newly-launched satellites represent third phase of BDS system (BeiDou-3). The first BeiDou-3 satellite was launched in March of 2015

BeiDou

BeiDou is 2nd generation of Chinese homegrown navigational system seen as rival to US’s Global Positioning System (GPS). It was named after Chinese term for plough or Big Dipper constellation.

It comprises constellation of total 35 satellites in two separate satellite constellations viz. limited test system (operational since 2000) and full-scale global navigation system which is currently under construction. The first BeiDou satellite was sent into space in 2000.

It became operational in December 2011, with constellation of 10 satellites providing services in China only. In December 2012, it began offering services to customers in Asia-Pacific region. On its completion in 2020, it will provide services to global customers.

Currently it used for civilian services in field of navigation, messaging, transportation and weather forecasting sectors. It also has military applications.

Nepal starts receiving internet connection from China

Nepal has started accessing internet from China after commercial operation of Nepal-China optical fibre link via Rasuwagadhi gateway across Himalayan Mountains became operational.

The commercial operation of Chinese bandwidth project now ends Nepal’s sole dependence on India for internet bandwidth. It is considered as loss for India, both revenue wise and strategically.

Key Facts

The actual volume of Chinese internet bandwidth that Nepal will receive has not been disclosed. It believed that initial speed by Chinese fibre link will be 1.5 Gigabit per second (gbps), less than 34gbps provided by India.

Chinese internet bandwidth will provide alternative source for Nepal to meet ever-increasing bandwidth demand as use of Internet has been increasing rapidly in the Himalayan country.

Chinese Internet gateway is also expected to facilitate service providers in Nepal to establish bandwidth connection with other countries via China. It is also considered as milestone for developing internet infrastructure in Nepal and boost bilateral relations between both countries.

Background

Nepal is currently linked to global internet connectivity through Indian telecom operators via different optical fibre connections in Biratnagar, Bhairahawa and Birgunj, among others. This gave India complete monopoly in supplying internet to Himalayan nation. In December 2016, state owned Nepal Telecom (NT) had signed Memorandum of Understanding (MoU) with China Telecom to acquire internet bandwidth. NT had begun test transmission of project from September 2017.
