Multi-mode receiver design application solution based on OTrack-32 chip

Lianxing OTrack-32 multi-system compatible satellite navigation chip adopts Host-Base architecture design, which can be combined with different performance CPUs to meet the receivers of various carrier applications. OTrack-32 is compatible with ARM, MIPS and other processor types, supports up to 4 channels of RF signal input, and is currently compatible with receiving Beidou II/GPS/GLONASS signals, and can be extended to support Galileo signals in the future. The OTrack-32 chip uses a new matched filter-based capture structure that is significantly superior in power and area to traditional structures, enabling simultaneous capture of multiple satellite signals.

The channel can stably track BD2, GPS or GLONASS respectively. The channels are completely independent and have no influence on each other. They have good flexibility. Different tracking strategies can be implemented through different parameter configurations in different application backgrounds. This ensures stable tracking even in the case of weak signals.

Based on the excellent performance of OTrack-32 and the deep accumulation in the field of satellite navigation, Lianxing has broken through a number of key technologies and formed a mature and systematic high-performance satellite navigation receiver design that can adapt to different sports characteristics. Application requirements for class carriers.

The multi-mode receiver design and application solution based on OTrack-32 chip has better interface adaptability, and can flexibly connect external storage, communication, display and other interfaces, and can form a variety of satellite navigation application terminals through simple integration.
