Beidou Star Communication and Rongzhi Time and Space have obtained patents related to receiver chassis, with integrated design to improve testing efficiency, making it portable, low-cost, and flexible to use.

On March 28, news reports show that the National Intellectual Property Administration's information indicates that Beijing Beidou Xingtong Navigation Technology Co., Ltd. and Beijing Rongzhi Shikong Technology Co., Ltd. have applied for a patent titled "A Dark Box for Receiver Testing," with the authorization announcement number CN224052233U, and the authorization announcement date is March 27, 2026. The application number is CN202423187715.0, the application publication date is March 27, 2026, and the application date is December 23, 2024. The inventors are Wang Xiaoqiang, Liu Xiangwen, Zhao Xiaogang, Ma Chunyan, and Gu Pengfei, with the patent agency being Beijing Anxin Fangda Intellectual Property Agency Co., Ltd., and the patent agents are Li Mengmeng and Li Ruomu, classified under G01R1/04.

The patent abstract shows that this application discloses a dark box for receiver testing, including: a box body; a transmitting antenna, which is installed inside the box body; and a mounting seat, which is slidably installed within the box body and set up for installing testing products. This receiver testing dark box integrates the transmitting antenna and mounting seat within the box body, and compared to a darkroom, this separately designed dark box no longer requires reservations and has no complicated processes, which can improve the efficiency of testing the signals sent and received by the receiver; the overall volume of the dark box is small and easy to move, achieving a portable design that can be customized in certain quantities as needed, facilitating receiver testing and offering more flexibility in use; when using this dark box for testing, only the manufacturing cost of the dark box and the costs for fixing different receivers are required, significantly reducing costs.

Beidou Xingtong was established on September 25, 2000, and went public on the Shenzhen Stock Exchange on August 13, 2007, with both its registered and office addresses located in Beijing. It is a leading company in the domestic navigation field, with its core business covering chips, navigation products, etc., and possesses deep technological accumulation and advantages across the entire industrial chain.

Beidou Xingtong's main business includes chips and data services, navigation products, ceramic components, and automotive electronics, falling under the Shenwan industry classification of national defense and military industry - military electronics II - military electronics III, involving segments such as single-vehicle concepts, shared economy, and the Internet of Things.

In terms of operating performance for 2025, Beidou Xingtong reported revenue of 2.213 billion yuan, ranking 4/9 in the industry, far below the first-ranked AVIC Optoelectronics at 21.386 billion yuan and the second-ranked Haige Communication at 4.388 billion yuan, above the industry median of 1.794 billion yuan, but below the industry average of 3.827 billion yuan. Among its main businesses, product sales are 2.088 billion yuan, accounting for 94.36%. The net profit is -282 million yuan, ranking 8/9 in the industry, with a significant gap compared to AVIC Optoelectronics at 2.35 billion yuan and Hongming Electronics at 461 million yuan, lower than the industry average of 215 million yuan and the median of 30.356 million yuan.
