1. Tracking sensitivity: the lowest GNSS signal value at the antenna port on which the module can keep

on positioning for 3 minutes.

2. Reacquisition sensitivity: the lowest GNSS signal value at the antenna port on which the module can

fix position again within 3 minutes after loss of lock.

3. Cold start sensitivity: the lowest GNSS signal value at the antenna port on which the module fixes

position within 3 minutes after executing cold start command.

4. “*” means under development.

4.3. Layout Guidelines

The following layout guidelines should be taken into account in your design.

 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 50Ω characteristic impedance for the ANT_GNSS trace.

Please refer to Chapter 5 for GNSS antenna reference design and antenna installation information.
