The UBX-M8030 from u-blox are Precision GNSS Chips that have been designed to provide good sensitivity and fast acquisition times for GNSS systems. They can receive concurrent signals from up to three GNSS systems (GPS/Galileo with either BeiDou or GLONASS) to allow for high positioning accuracy in urban canyons, even with weak signals and high dynamic conditions. These GNSS chips are ideal for low-cost portable consumer devices and can be upgraded for backward compatibility. They require a DC supply of 1.4-3.6 V, consume 21 mA of current, and have low power consumption in concurrent reception mode.
These AEC-Q100-qualified GNSS chips also utilize advanced Power Save modes for all constellations while maintaining low power consumption when detecting weaker GNSS signals. They support message integrity protection, geo-fencing, and spoofing detection with configurable interface settings to easily fit customer applications. The UBX-M8030 chips include a built-in low noise amplifier (LNA), LDOs, a DC-DC converter, and a small external BOM to enable ultra-small solutions with a footprint of 30 sq-mm. They also integrate robust TCXOs or other low-price oscillators to further ensure a minimal total cost of ownership.
The UBX-M8030 chips have a cold-start time of 26 s, an aided start time of 2 s, and a hot-start time of 1 s. They have a tracking sensitivity of -167 dBm and a reacquisition sensitivity of -160 dBm. These GNSS chips integrate UART, USB, DDC (I2C compliant), and SPI serial interfaces to remotely control and develop customer applications. They are available in a 47-lead wafer-level package that measures 2.99 x 3.21 x 0.36 mm and are ideal for standard, professional, and automotive applications.
