RTK GNSS built-in antenna
GNSS: L1 L2
GPS+GALILEO+GLONASS+BEIDOU
Features
The antenna part adopts a multi-feed point design and a completely symmetrical antenna structure, with a relatively stable phase center, reducing the influence of the antenna on measurement errors;
The antenna gain is high, the pattern beam is wide, and the receiving effect of low-elevation signals is good, ensuring that the satellite can be received normally in some severely obstructed occasions;
The noise amplifier part adopts pre- and multi-stage filtering schemes, which can effectively suppress strong out-of-band interference signals and ensure that it can be used in harsh electromagnetic environments.
Application field
The four-system seven-frequency built-in measurement antenna is a built-in GNSS antenna that covers GPS L1/L2, BDS B1/B2/B3, GLONASS L1/L2, GALILEO E1, E5b. High-precision requirements can be widely used in surveying and mapping, deformation monitoring, precise positioning, mobile mapping, construction machinery control, and precision agriculture.

Product features：
1. Using multi feed point design to ensure the superposition of phase center and geometrical center which
could minimize the influence of measurement error to lowest range
2. High gain of the antenna element and the direction map beam width to make sure the receiving satellites
performance of low elevation mask
3. Resistance multipath effects board inside could reduce the measurement error caused by multipath
4. Water proof, shock proof and lightning resistance
Survey antenna is the traditional RTK product standard antenna,can be widely used in land survey,marine
survey,channel survey,seismic monitoring,bridge survey,container opertion,etc.
