The UBX-M9140 from u-blox AG is a GNSS SoC that supports GPS (L1 C/A), QZSS (L1 C/A/S), GLONASS (L10F), BeiDou (B1I), Galileo (E1B/C), SBAS (L1 C/A: WAAS), EGNOS, MSAS and GAGAN bands. The module supports concurrent reception of four visible GNSS satellites which enables the receiver to select the best signals and maximize position accuracy in urban areas.
The UBX-M9140 SoC delivers meter-level accuracy with a tracking and navigation sensitivity of -167 dBm and a reacquisition sensitivity of -160 dBm. It has a hot start of 2 seconds, an aided start of 2 seconds and a cold start of 24 seconds. The SoC requires a DC supply of 1.8-3.0 V and can be controlled via UART, USB, DDC (I2C compliant) and SPI interfaces. It has an integrated TCXO oscillator, 8 MBit flash memory and a DC-DC converter (built-in/external).
The UBX-M9140 supports concurrent reception of four visible GNSS satellites which enables the receiver to select the best signals and maximize the position accuracy in urban areas. This SoC offers a position update rate of 25 Hz to receive position information for dynamic applications. It detects RF interference, jamming and spoofing events and reports them to the host so that the system can react to such events. The SoC uses advanced in-band filtering algorithms to mitigate the impact of RF interference and jamming, thus enabling the chipset to operate as intended. It is available in a QFN package that measures 5 x 5 x 0.59 mm and is ideal for automotive and industrial tracking applications such as navigation, telematics, and UAVs.
