BEITIAN NEW 3-6V drone UAV Helix RTK GNSS Antenna Ubx ZED-F9P Module Receiver helical spiral GPS antenna BT-3070
Model:BT-3070
Product Introduction
BT-3070 antenna employs quadrifilar helical structure to receive signals of GPS L1/L2, GLONASS G1/G2, BDS B1/B2/B3 and GALILEO E1/E5b bands，which features high zenithal gain, favorable low elevation gain, wide-angle circular polarization and stable phase center. The antenna is suitable for Four-system high-precision survey and military positioning and widely used in situations such as unmanned aerial vehicles, geodetic survey, road construction, marine survey, wharf container operation, maneuvers and frontier guard.
Features
quadrifilar helical structure is adopted to ensure favorable gain and axial ratio at low elevation, coincidence of phase center and geometric center and minimal influence to measurement precision.
Wide beam of radiation pattern can make sure good reception of signals at low elevation and normal operation in some situations of serious shielding.
The radome can resist high and low temperature impact, water, and ultraviolet rays, which can protect the antenna to work outdoors all the year round.
