GNSS and GPS L1/L2/L5 Antennas

GNSS and GPS L1/L2/L5 Antennas

OPTIMAL CONNECTIVITY LLC offers Engineering Services, Product Design, Co-Design and industrial production capabilities for manufacturing and testing of GNSS antenna solutions. Our antennas are able to receive GNSS Frequency Band and GPS frequency bands. The GNSS frequency bands include GLONASS, Galileo, Compass CPII/Beidou, IRNSS. The GPS frequency bands include GPS L1, GPS L2, GPS L5, QZSS L2C, QZSS E6, QZSS L1.

The use of multiple providers of positioning data can increase the location accuracy. Together with correctional positioning data like RTK Differential Positioning Systems can achieve an accuracy on cm level in x, y and z coordinate location.
