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 AEC-Q100-qualified GNSS chips also utilise 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.
The chips include a built-in low noise amplifier, LDOs, a DC/DC converter, and a small external BoM to enable ultra-small solutions with a footprint of 30 mm2. They require a DC supply of 1,4 to 3,6 V, and consume only 21 mA of current.
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.
With the ability to track 72 channels providing a 2 m accuracy, these GNSS chips are ideal for low-cost portable consumer devices.
