■ Concurrent reception of GPS, GLONASS, BeiDou in Super-E mode
■ Minimal board space: less than 30 mm²
●Product description：
■The UBX-M8230-CT is an ultra low power GNSS chip optimized for wearable and portable applications. It features Super-E mode (Super-Efficient), providing a unique balance between power and performance. Compared with u-blox 1 Hz full power mode, the Super-E mode provides up to 3 times the power savings while maintaining good position and speed accuracy. Average power consumption over a typical 30-minute track can be lower than 20 mW, while instantaneous tracking power is less than 10 mW. This is true even when using an industrial antenna design with moderate-to-low signal levels.
■Super-E has a default performance setting for the best balance between power vs. performance. It also has a power save setting for additional power savings with potential compromise on performance.
■The UBX-M8230-CT optimizes the overall system power consumption by excluding the need for any heavy signal processing on the application processor, and with external components, such as an external LNA, that can be automatically duty cycled. Navigation data can be stored internally while the application processor is in deep sleep (data batching). Used in combination with multi-GNSS Assistance data, the UBX-M8230-CT features faster Time-to-First-Fix and ensures minimal power consumption.
■The UBX-M8230-CT only needs a few external components (e.g. SAW/LNA) to form a full GNSS solution with a footprint as small as 30 mm2. It offers easy access to navigation data via multiple interfaces, such as SPI, I2C and UART.
■The UBX-M8230-CT chip is an ideal choice for most wearable applications, such as watches, sport trackers and other applcations where low power consumption and small size are key.
■The UBX-M8230-CT is built on the u-blox M8 concurrent engine and supports two constellations simultaneously in Super-E mode, thus increasing the number of visible satellites compared to single-GNSS solutions. It also supports message integrity protection, anti-jamming, and anti-spoofing, providing reliable positioning in difficult environmental conditions as well as in security attack scenarios.
■The UBX-M8230-CT chip is fully tested and qualified accord-ing to the JESD47 standard.
