How GNSS Antennas Improve RTK Accuracy

Accurate positioning is the backbone of modern surveying, agriculture, construction, and autonomous systems. A professional GNSS Antenna ensures stable signal reception, centimeter-level RTK precision, and multi-system compatibility. VLG’s High-Precision Multi-System RTK GNSS Survey Antenna is engineered to meet these requirements, offering full-band multi-constellation support and reliable performance even in challenging urban and outdoor environments.

Common Causes of GNSS Positioning Errors

Even advanced GNSS receivers cannot compensate for poor antenna performance. Common challenges include:

• Multipath interference from nearby structures
• Limited satellite visibility in urban canyons or dense foliage
• Phase center instability causing measurement drift
• Environmental conditions such as rain, dust, or extreme temperatures

A high-quality GNSS Antenna addresses these challenges by maintaining stable multi-frequency reception and precise phase center alignment.

VLG GNSS Antenna Key Specifications

The VLG RTK GNSS antenna supports GPS, BDS, GLONASS, Galileo, and L-Band signals simultaneously, ensuring compatibility with most modern receivers.

Electrical and Mechanical Features:

These specifications ensure robust RTK positioning even in challenging field conditions.

Single-Frequency vs Multi-Frequency GNSS Antennas

VLG’s multi-frequency GNSS antenna provides superior stability, faster RTK initialization, and better performance in environments where single-frequency antennas fail.

RTK Performance and Multi-System Benefits

The antenna’s multi-feed symmetrical design aligns the phase center with the geometric center, minimizing micro-displacement errors. Multi-system support includes:

• GPS: L1 / L2 / L5
• BDS: B1 / B2 / B3
• GLONASS: L1 / L2
• Galileo: E1 / E5a / E5b / E6
• L-Band correction signals

This ensures faster satellite acquisition, reduced RTK initialization time, and reliable positioning in urban, rural, or obstructed environments.

Industrial Applications of VLG GNSS Antennas
