Product description

The UBX-M8030 high performance standard precision GNSSchips from u-blox, provide exceptional sensitivity and acquisitiontimes for all GNSS systems. The chips utilize concurrentreception of up to three GNSS systems (GPS/Galileo togetherwith Beidou or GLONASS). Reception from more than oneconstellation simultaneously allows extraordinary positioningaccuracy in urban canyons, even with weak signals and highdynamics.

The UBX-M8030 chips feature low power consumption inconcurrent reception mode and support advanced Power SaveModes for all GNSS, the power consumption remains low evenfor weak signals. The UBX-M8030 chips also support messageintegrity protection, geofencing and spoofing detectionwith configurable interface settings to easy fit to customerapplications. The firmware supports QZSS, GAGAN and IMEStogether with WAAS, EGNOS, MSAS.

UBX-M8030 chips are available in miniature WL-CSP and QFNpackages. Featuring built-in LNA, LDOs and DC/DC converter,and a small external BOM, the UBX-M8030 enables ultra-smallsolutions with a footprint of only 30 mm2. Supporting TCXOsor lower price oscillators further ensures a minimal Total-Costof-Ownership.

The ultra small UBX-M8030-CT is a perfect choice for portableconsumer applications with demanding size and cost constraints.Including rigorous automotive quality and manufacturingstandards, extended testing and low failure rate make the UBXM8030-KAchip ideal for automotive applications. With UBXM8030-KA’soperational tempature from -40° to +105°C, anew industry standard is set.Migration from existing FW2 based u-blox M8030 chip designsare simple, since the upgraded UBX-M8030 offers backwardcompatibility.
