Beidou, China's answer to the US-owned GPS navigation system, will back domestic products and related services worth 1 trillion yuan (US$156.22 billion) by 2025, the official Xinhua news agency said on Wednesday.

The homegrown Chinese navigation network, completed in June 2020, looks to offer an alternative to the Global Positioning System (GPS) run by the US Air Force, spurring further growth in the domestic satellite market.

Related Beidou products have been exported to about 120 countries, serving more than 100 million users worldwide, according to Xinhua news agency

China's satellite navigation industry has been growing at a rate of over 20 percent in value on average each year to exceed 400 billion yuan in 2020, Xinhua reported, citing data presented at an industry conference in the southern province of Jiangxi.
