Overview

G90A-F20 GNSS module features the u-blox M9 standard precision GNSS platform and provides exceptional sensitivity and acquisition time for all L1 GNSS signals..G90A-F20 is a Ultra-robust meter-level GNSS positioning solution. The receiver also provides higher navigation rate and improved security features compared to previous u-blox GNSS generations. G90A-F20 supports a maximum positioning update rate of 25Hz. It is suitable for serving automotive and industrial tracking applications, such as navigation, telematics and UAVs.
The UBX-M9140 chips are part of the u-blox M9 standard precision GNSS platform, and provide exceptional sensitivity and acquisition times for all L1 GNSS systems. The u-blox M9 standard precision GNSS platform, which delivers meter-level accuracy performance, succeeds the well-known u-blox M8 product range.
UBX-M9140 supports concurrent reception of four GNSS(GPS GLONASS Galieo BeiDou)with QZSS SBAS enbale. The high number of visible satellites enables the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as in deep urban canyons.
UBX-M9140 offers a position update rate of up to 25 Hz. This allows dynamic applications such as UAVs to receive the position information with low latency.
UBX-M9140 detects jamming and spoofing events and reports them to the host, so that the system can react to such events. Advanced filtering algorithms mitigate the impact of RF interference and jamming, thus enabling the product to operate as intended.
G90A-F20 module supports NMEA,UBX and RTCM protocols.
G90A-F20 module has built-in Flash memory and supports customization of various configurations of the module.

In the default configuration, the NMEA-GSV messages are sent at 5-second intervals to avoid overflow in the TX buffer.
