NEO-8Q - GNSS module with u-blox 8 engine

The NEO-8Q is a standard precision GNSS module, built on the reliable performance of the u-blox 8 GNSS engine for GPS, GLONASS, QZSS and SBAS signals.

The NEO-8Q standard precision GNSS module is built on the reliable performance of the u-blox 8 GNSS engine, which receives GPS, GLONASS, QZSS and SBAS signals. The NEO-8Q delivers high sensitivity and minimal acquisition times in the industry proven NEO form factor.

It features low power consumption and supports advanced Power Save Modes. It also provides message integrity protection, geofencing, spoofing detection, and odometer functionalities.

NEO-8Q is an economical choice for best performance and easier RF integration. For RF optimization the NEO-8Q features an additional front-end LNA for easier antenna integration and a front-end SAW filter for increased jamming immunity. The industry proven NEO form factor allows easy migration from previous NEO generations. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments.

The NEO-8Q combines a high level of robustness and integration capability with flexible connectivity options. The DDC (I²C compliant) interface provides connectivity and enables synergies with most u-blox cellular modules.

Key Features:
  • High sensitivity of -166 dBm for single GNSS reception
  • Cost‑efficient system
  • TCXO‑based product enables fastest time to first fix
  • Low power consumption
  • Superior anti‑spoofing and anti‑jamming
