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.
3.3 Layout Guidelines
The following layout guidelines should be taken into account in application designs.
 Maximize the distance between GNSS antenna and main antenna.
 Digital circuits such as (U)SIM card, USB interface, camera module, display connector and SD card
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 ANT_GNSS trace.
Please refer to Chapter 5 for GNSS antenna reference design and antenna installation information.
