6. PCB Layout Recommend 
Recommended Layout Pad 
 
PCB Layout Recommendations 
 Do not routing the other signal or power trace under the module board. 
RF: 
 This pin receives signal of GPS analog via external active antenna. Note: It has to be a 
controlled impedance trace at 50ohm. 
 Do not place the RF traces close to the other signal path and not routing it on the top layer. 
 Keep the RF traces as short as possible. 
Antenna: 
 Keep the active antenna on the top of your system and confirm the antenna radiation pattern、 
axial ratio、power gain、noise figure、VSWR are correct when you Setup the antenna in your case. 
 
  
 
7. Configuration Management 
Configuration settings can be modified with configuration messages. The modified settings remain 
effective until power-down or reset. If these settings have been stored in battery-backup RAM, 
then the modified configuration will be retained, as long as the backup battery supply is not 
interrupted. 
Note that: If any new configuration needs to be done, pls refer to module Receiver Description 
Including Protocol Specification.
