4.2. GNSS Antenna Interface
The GNSS part of MC60 module supports both GPS and GLONASS systems. The RF signal is obtained
from the GNSS_ANT pin. The impedance of RF trace should be controlled as 50 Ohm, and the trace
length should be kept as short as possible.
4.2.1. Antenna Specifications
The module can be connected to a dedicated GPS/GLONASS passive or active antenna to receive
GPS/GLONASS satellite signals. The recommended antenna specifications are given in the following
table.
