Anti-interference GNSS positioning antenna structure for marine surveying and mapping

Abstract

The utility model discloses an anti -interference GNSS positioning antenna structure for ocean surveying and mapping relates to ocean surveying and mapping and antenna technical field. The structure includes support pole, adjusting base, fixed base plate, radiator and connecting feeder. The support pole lower extreme welds adjusting base, and the bottom surface welds fixed base plate, and the upper end installs radiator, and the radiator is connected the feeder through metal interface. Adjusting base adopts double rotation adjusting structure: through one inner clamping groove ring, one inlay block, one toothed block and one spring, realizes the inclination angle adjustment of radiator, realizes the adjustment to the direction through two inner clamping groove rings, two inlay blocks, two toothed blocks and two springs, and the toothed block is cooperated with the clamping groove and is guaranteed angle fixed firm, can be nimblely aimed at satellite signal intensity direction, promotes the receiving efficiency. Fixed base plate adopts inner hexagonal screw and double fixedness of sticky layer, and the screw guarantees long -term firm installation, and the sticky layer temporarily maintains stable when the screw loosens, and rubber pad plays the role of buffering and antiskid, and enhances the installation reliability.
