NOTES
1. Tracking sensitivity: the minimum GNSS signal power at which the module can maintain lock (keep
positioning for at least 3 minutes continuously).
2. Reacquisition sensitivity: the minimum GNSS signal power required for the module to maintain lock
within 3 minutes after loss of lock.
3. Cold start sensitivity: the minimum GNSS signal power at which the module can fix position
successfully within 3 minutes after executing cold start command.
4.3. Layout Guidelines
The following layout guidelines should be taken into account in customers’ design.
• Maximize the distance among GNSS antenna, main antenna and Rx-diversity antenna.
• Digital circuits such as (U)SIM card, USB interface, camera module and display connector should be
kept away from the antennas.
• Use ground vias around the GNSS trace and sensitive analog signal traces to provide coplanar
isolation and protection.
• Keep 50 Ω characteristic impedance for the ANT_GNSS trace.
Please refer to Chapter 5 for GNSS antenna reference design and antenna installation information.
