ZYAXX-S315/S005/S715:
This series of antennas comprises:a single frequency GPS antenna, dual-satellite system(GPS+GLONASS) with singlefrequency antenna(L1);a dual-frequency GPS antenna(L1,L2),dual-satellitesystem(GPS+GLONASS)with dual-frequency antenna(L1,L2); a triple-satellitesystem(GPS+GLONASS+BeiDou)antenna as well as various other satellitecombinations and types of antennas. Any of these antennae can be widely used ingeodesy, marine surveying, tunnel surveying, earthquake monitoring, bridgedeformation monitoring, landslide monitoring, port container operations, etc. Toimprove measurement accuracy this series of antenna eemploys a multiplefeed-point design to ensure the coincidence of the antenna phase centre and thegeometrical centre. The antenna efeature: high unit gain, wide directionalpattern beam width, small size and light weight.
