SAM-M8Q - u-blox GNSS patch antenna module

u-blox patch antenna module using the M8 concurrent GNSS (GPS/GLONASS/Galileo/QZSS/SBAS) engine for easy and reliable GNSS integration.

SAM-M8Q is the u-blox GNSS patch antenna module that is ideal for easy and reliable GNSS integration. With the exceptional performance of the u-blox M8 concurrent GNSS (GPS, GLONASS, Galileo, QZSS and SBAS) engine, the SAM-M8Q delivers high sensitivity and minimal acquisition times in a compact form factor.

Low power consumption, a simple interface, and sophisticated interference suppression ensure maximum performance even in GNSS-hostile environments. In addition, the 15 x 15 mm patch antenna provides the best compromise between the performance of a Right Hand Circular Polarized (RHCP) antenna and a small size to be integrated in any design and the omni-directional radiation pattern increases flexibility for device installation. The module also provides message integrity protection, geofencing, spoofing detection, and odometer functionalities as well as an additional front-end LNA for optimised performance and a front-end SAW filter for increased jamming immunity.

Key features:

  • Easy to design‑in; no RF expertise required
  • Consistently strong performance regardless of installation
  • High accuracy thanks to concurrent reception of up to 3 GNSS (GPS, Galileo, GLONASS)
  • Small form factor 15.5 x 15.5 x 6.3 mm
  • Embedded wide‑band patch antenna
  • Surface‑mount device, enabling simple and automated manufacturing
