A GNSS (Global Navigation Satellite System) antenna receives signals from satellites such as GPS, GLONASS, Galileo, BeiDou, and QZSS to determine precise position, velocity, and time. High-precision antennas like those from TOPGNSS are designed for RTK, surveying, UAVs, and timing applications.
L1 (1575.42 MHz) is the primary GPS band. L2 (1227.60 MHz) improves accuracy and enables ionospheric correction. L5 (1176.45 MHz) offers higher power and better resistance to interference, ideal for safety-of-life and high-precision applications.
Yes. TOPGNSS offers full OEM/ODM services including custom form factors, frequency tuning, connector types, cabling, and branding for volume orders.
Absolutely. Our antennas support GPS, GLONASS, Galileo, BeiDou, QZSS, and IRNSS across L1, L2, and L5 bands for maximum satellite visibility and reliability.
Our products are used in surveying, UAVs, autonomous vehicles, smart agriculture, marine navigation, deformation monitoring, timing infrastructure, and defense applications.
