Mini Survey Antenna

GPS400 receives GPS L1/L2 and GLONASS L1/L2 frequencies, which can be used in land survey, marine survey, channel survey, seismic monitoring, bridge survey, container operation, agriculture applications. Customers can use the same antenna for GPS only or dual constellation applications.

It has high gain and wide beam width to ensure the signal receiving performance of satellite at low elevation angle. The phase center of this antenna remains constant as the azimuth and elevation angle of the satellites change. Signal reception is unaffected by the rotation of the antenna or satellite elevation, so placement and installation of the antenna can be completed with ease.

• Support GPS L1/L2 GLONASS L1/L2 frequencies.
• Multi-path rejection board inside can eliminate the multi-path influence to measurement error.
• Adopt multi feed design to ensure the superposition of phase center and geometrical center, and minimize the influence to b measurement error.
• Water & dust-proof design ensures absolute seal of kernel parts, capable for long time outdoor operation.
• Very low noise figure.
• Lightning proof circuit inside can protect the LNA from being damaged by surge immunity.
