OTrack-128/OTrack-128A multi-mode and multi frequency chip

OTrack-128 is a new generation Beidou satellite navigation chip launched by Lianxing. The chip adopts a 32-bit high-performance ARM embedded processor, built-in BDS/GPS/GLONASS/Galileo algorithm engine baseband module, integrated DMA controller, USB1.1 device and other related IO peripheral devices. It has a small size (12mmx12mmx1.25mm), advanced technology, flexible packaging, supports ceramic and plastic packaging, strong anti-interference ability, and can eliminate up to 12 narrowband interferences.

OTrack-128A is a high-performance Beidou satellite navigation baseband SIP chip. This chip integrates OTrack-128 die, SPI-FLASH, and SDRAM through SIP, achieving better board level design and higher integration. A single-chip solution that can interconnect with multiple devices, adapt to various applications, and provide independent navigation functionality.

Can achieve multi-mode and multi frequency navigation: supports frequency points BDS B1/B2/B3, GPS L1/L2C/L5, GLONASS F1/F2, Galileo E1/E5, BDS RDSS services, and A-GNSS.
