A worker shows radio frequency chip Hengxing-1 at the ninth China Satellite Navigation Conference in Harbin, capital of Heilongjiang province, May 24, 2018. The chip, which could be used for receiving and sending signals from Beidou-3 satellites, is developed by Guangzhou-based company Hi-Target Surveying Instrument. This chip, of which the Hi-Target company has independent intellectual property rights, adopts a highly integrated design and is available for use in the current four navigation systems from the US, Russia, Europe and China. It's estimated that Hengxing-1 will be put into production in the second half of 2018 and largely replace imported chips by the end of this year, according to the company.
