    MIA-M10C. MIA-M10C is configured using UBX configuration interface keys. The configuration database in the receiver's RAM holds the current configuration, which is used by the receiver at runtime. It is constructed at the receiver startup from several sources of configuration.

  • Page 11: Basic Receiver Configuration

    10 receivers support three modes for the internal low-noise amplifier (LNA): normal gain, low gain, and bypass mode. The MIA-M10C default is the normal mode. With a high-gain external active antenna, the low gain or the bypass mode can be used to save power.

    2.3 OTP memory configuration MIA-M10C contains a one-time programmable (OTP) memory. This is a non-volatile memory for storing configuration settings and ROM patches permanently in the device. The stored data cannot be modified after it has been initially programmed. The device applies the settings and ROM patches on the device startup.

  • Page 21: Receiver Functionality

    For receiving correction data, MIA-M10C automatically chooses the best SBAS satellite as its primary source. It selects only one satellite since the information received from other SBAS satellites is redundant and could be inconsistent.

  • Page 22: Qzss Slas

    Multiple QZSS SLAS signals can be received simultaneously. When receiving QZSS SLAS correction data, MIA-M10C will autonomously select the best QZSS satellite. The selection strategy is determined by the quality of the QZSS L1S signals, the receiver configuration (test mode allowed or not), and the location of the receiver with respect to the QZSS SLAS coverage area.

The receiver monitors the background noise and looks for significant changes in the spectrum.

  • Page 38: Power Management

    3.6.1 Continuous mode MIA-M10C uses dedicated signal processing engines optimized for signal acquisition and tracking. The acquisition engine actively searches for and acquires signals during cold starts or when insufficient signals are available during navigation. The tracking engine continuously tracks and downloads all the almanac data and acquires new signals as they become available during navigation.
  • Page 39 MIA-M10C - Integration manual • Tracking state: the receiver continuously tracks and downloads data. Less power consumption than in the acquisition state. • POT state: the receiver repeatedly loops through a sequence of tracking (Track), calculating the position fix (Fix), and entering an idle period (Idle). No new signal is acquired and no data is downloaded.
  • Page 40 MIA-M10C - Integration manual • The receiver is forced to stay awake if EXTINTWAKE is enabled and the EXTINT pin is set to "high". The receiver is forced to stay in the "Inactive for search/Fix" states if EXTINTBACKUP is enabled and the EXTINT pin is set to "low".

Setting the search period ACQPERIOD to zero causes the receiver to wait in the "Inactive for search" state indefinitely after an unsuccessful startup.

Also, the CFG-NAVSPG- UTCSTANDARD configuration item allows the user to select which variant of UTC the receiver should use.

  • Page 47: Itow Timestamps

    MIA-M10C - Integration manual The GNSS system time calculated in the navigation solution is always converted to a time in both the GPS and UTC time bases for output. Clearly when the receiver has chosen to use the GPS time base for its GNSS system time, conversion to GPS time requires no work at all, but conversion to UTC requires knowledge of the number of leap seconds since GPS time started (and other minor correction terms).

Note that information about time validity confirmation is only available if the confirmedAvai bit in the UBX-NAV-PVT message is set. validDate means that the receiver has knowledge of the current date. However, it must be noted that this date might be wrong for various reasons.

  • Page 49: Date Ambiguity

    MIA-M10C - Integration manual Occasionally, a "leap second" is announced to bring UTC back into close alignment with the mean solar time. Usually this means adding an extra second to the last minute of the year, but this can also happen on 30th June. When this happens, UTC clocks are expected to go from 23:59:59 to 23:59:60, and only then on to 00:00:00.

Refer to the MIA-M10C Data sheet [1] for absolute maximum ratings, operating conditions, and power requirements. 4.1.1 VCC VCC provides power to the core and RF domains and must be supplied during normal operation. A filtered VCC supply is available on the VCC_RF pin.

    Voltage at VCC_RF pin = VCC - 0.1 V. Table 31: Voltage supply options MIA-M10C uses the DCDC_EN pin to disable an external DC/DC converter during the software standby mode or power save mode on/off (PSMOO) operation. This is commonly used in designs without V_BCKP supply.

    This limits the maximum value for the voltage divider resistors.

    This section provides some reference designs for typical and antenna supervisor design cases. B.1 Typical design Here are some key features for a MIA-M10C typical design: • The main supply(VCC) is 1.8 V. VCC and V_IO are connected together to a single supply in the case when 1.8 V V_IO supply is used.
  • Page 85 RTC can be dropped. In that case, the RTC_O pin must be connected to GND. • This design uses an active antenna, which can be supplied either with the VCC_RF output from MIA-M10C, as shown in Figure 38, or from an external supply, as shown in Figure 39.

    TTFF. • An active antenna can be supplied with the VCC_RF output from MIA-M10C or from an external supply. VCC_RF is a filtered output voltage supply, which outputs VCC - 0.1 V. For MIA-M10C, the VCC_RF outputs about 1.7 V which might not be sufficient to supply some active antennas.

Likewise, disable the UART interface (CFG-UART1-ENABLED) or TIMEPULSE (CFG-TP-TP1_ENA) when the pins are used for antenna supervisor functions.
