GPS antennas are often designed to cover wider GNSS which refers to global navigation systems and includes GPS, Glonass, BeiDou, and Galileo. We provide design services for integrated single(L1) and dual-band(L1+L2) GNSS solutions.
Navigation satellites transmit right-hand circular polarized signals, which need to consider on the receiver antenna design. The benefit of circular polarization on user equipment is the removal of reflection that would otherwise degrade reception sensitivity. However, many devices operate well with only a linear polarized antenna which is easier to integrate into the user equipment.
GNSS receivers might be assisted or standalone. Standalone devices do not have other means for location service than satellite signals which put high expectations for GNSS antenna performance.
