At least 80 % of apps and services available in China were compatible with the Beidou Navigation Satellite System (BDS), an alternative to US-operated GPS. Services based on the BDS are used not only for industrial purposes such as geographic surveying, traffic monitoring and agriculture, but also for car navigation and positioning services on mobile phones. Annual revenue is reported as 134 billion Yuan in 2014. China launched the 18th and 19th BDS satellites in July, for 2020 a complete set of 35 satellites is planned.
