Main Feature
S440 is a set of GPS L1L25:GLONASS G1.G2. Beidou2 B1.B2,B3 and Galleo E1.E2,E5a.E5b four system active antenna. can be widely used ingeodesy, bridge construction, marine surveying, underwater topography measurement etc.
The antenna using mult feedpoint design, ensure the antenna phase center and the geometric center of the coincidence, improve the accuracy ofmeasurement. Antenna element has hih gain and wide beamwidth to ensure the sional receiving performance of satelite at low elevation andle. Muliath reecton board inside can e miate the mu t-pat intuence to measurement error. Bud-n ow norse amo fer modure. throuon the mut-staofilter to eliminate interference sianal. ensure the normal work in harsh electromaanetic environment
