Development Path of Lianxing Company's Chip Industry

In 2008, Lianxing Company launched the world's first mature commercial Beidou multi-mode satellite navigation chip - OTrack-32, which can simultaneously receive BDS, GPS, and GLONASS satellite signals, achieving multi-mode joint positioning and has been widely used in various receivers. At present, Lianxing Company has successively developed a series of navigation specific chips and IP cores, which have been successfully applied in specialized fields such as mobile phones, vehicles, aircraft, missiles, and high precision. The multi-mode and multi frequency satellite navigation receiver and satellite communication navigation module built on the satellite navigation chip of Lianxing Company meet various application requirements.

OTrack AJ "is a high-performance satellite navigation anti-interference chip that supports multi element antennas and anti-interference processing of intermediate frequency signals for all satellite navigation systems. This chip has the ability to resist various types of interference, with superior anti-interference performance. Its anti single broadband interference signal-to-noise ratio is better than 95dB, and its anti multiple broadband interference signal-to-noise ratio is better than 85dB. Considering compatibility and ease of use, the output signal can be up converted to RF signal or directly output digital IF signal to baseband. Built in NOR Flash storage controller and external hardware parameter configuration controller.

ProNav is a high-performance navigation IP core that can handle BDS B1 signals, GPS L1 signals, and GLONASS F1 signals, including baseband processing circuits, baseband processing software, and position calculation software, providing a complete satellite navigation solution.

The latest OTrack-128/OTrack-128A chip developed by Lianxing Company supports high-precision functions and fully utilizes the Beidou enhanced network. Its accuracy can reach decimeter level or even centimeter level, enabling high precision to enter ordinary navigation modules and leading a new direction in global satellite navigation.
