Product catalog summary

Overview: The document provides technical specifications and operational details for a high precision GNSS active antenna, part number V3N-GGI-101. This antenna is designed for use in various applications such as geodesy, bridge construction, marine surveying, and autonomous vehicles.

Specifications:

Frequency Support: The antenna supports multiple satellite systems including GPS (L1, L2, L5), GLONASS (L1, L2, L3), Beidou2 (B1, B2, B3), Galileo (E1, E5a/b, E6), QZSS (L1, L2, L5), and IRNSS (L5, with optional S-Band).
Gain: 39 dB with a low noise amplifier (LNA) included.
Operation Voltage: 3V to 15V DC.
Impedance: 50Ω with a coverage angle of 360°.
Polarization: Right-Hand Circular Polarization (RHCP).
Dimensions: Ø185×70 mm with a TNC-C-K connector and two screw mounting.
Environmental Conditions: Operating temperature ranges from -40°C to +85°C, and reposition temperature from -55°C to +85°C.

Design Features:

The antenna uses a multi-feed point design to ensure the phase center coincides with the geometric center, enhancing measurement accuracy.
It includes a built-in low noise amplifier module with multi-stage filtering to eliminate interference, ensuring reliable operation in harsh electromagnetic environments.

Waterproof Operation Details:

Fit the hot-melt sleeve over the LMR-400 line.
Connect the LMR-400 cable to the V3N-RR-AA-01 receiving antenna.
Seal the joint with waterproof tape and use a hot air gun to heat the tape.
Push the hot melt casing on the support frame and heat it to form a protective waterproof film.

Additional Information: The document includes a frequency reference table and details on the global/compass navigation satellite systems (GNSS/CNSS) frequencies supported by the antenna.
