ZOE-M8G/M8Q - Ultra small multi-GNSS SiP modules

Ultra-compact GNSS SiP module for concurrent reception of up to 3 GNSS systems (GPS/Galileo and GLONASS or BeiDou)

ZOE-M8G and ZOE-M8Q are u-blox's latest, highly integrated System in Package (SiP) GNSS solutions based on the high performing u-blox M8 concurrent positioning engine. The new, record breaking ultra miniature form factor integrates a complete GNSS SiP, including SAW filter, LNA and TCXO.

The ZOE-M8 SiPs are targeted for applications that require a small size without compromising the performance. For RF optimization, the ZOE-M8 SiPs integrate a front-end SAW filter and an additional front-end LNA for increased jamming immunity and easier antenna integration. A passive antenna can be used to provide a highly integrated system solution with minimal eBOM.

Incorporating ZOE-M8 into customer designs is simple and straightforward thanks to the fully integrated design, single voltage supply (ZOE-M8G 1.8 V, ZOE-M8Q 3 V), low power consumption, simple interface, and sophisticated interference suppression that ensure maximum performance even in GNSShostile environments.

With its dual-frequency RF front-end, the ZOE-M8 SiPs are able to utilize concurrent reception of up to three GNSS systems (GPS/Galileo together with BeiDou or GLONASS). In addition, the ZOE-M8 SiPs provide an SQI interface for optional external Flash, allowing future firmware upgrades and improved A-GNSS performance.

Thanks to u-blox advanced algorithms and a complete GNSS solution, ZOE-M8 SiPs meet even the most stringent requirements in versatile industrial and consumer applications, such as UAVs, vehicles and assets tracking. The ZOE-M8 series also supports message integrity protection, anti-jamming, and antispoofing, providing reliable positioning in difficult environmental conditions as well as in security attack scenarios.

Features:
  • Ultra small size SiP 4.5 mm x 4.5 mm x 1.0 mm
  • Fully integrated and complete solution, reducing total design efforts
  • Ideal for passive antennas, due to built‑in SAW and LNA
  • High accuracy thanks to concurrent reception of up to 3 GNSS
  • -167 dBm sensitivity for reliable positioning in challenging conditions
