Antennas and accessories

The HX-CGX601A is a four-system full-band 3D choke antenna encompassing GPS, GLONASS, BDS, and GALILEO, meeting the current demands for high precision and multi-system compatibility in surveying equipment. It can be widely used in high-precision applications such as geodetic mapping, marine surveying, waterway surveying, dredging surveying, earthquake monitoring, bridge deformation monitoring, landslide monitoring, and container handling at docks.

Full-band signal compatibility

It covers the full frequency bands of the four major GNSS systems and L-Band signals, meeting the current requirements for multi-system compatibility and interoperability.

Highly stable phase center

The antenna employs a unique three-dimensional choke coil structure design, providing excellent resistance to multipath interference. The antenna section utilizes a unique four-feed point design, achieving a high degree of coincidence between the phase center and the geometric center, minimizing the antenna's impact on measurement errors. Data from tests conducted by authoritative third-party institutions shows that the HX-CGX601A achieves sub-millimeter-level phase center stability, making it an ideal choice for applications such as ground-based reference stations, bridge and high-rise building deformation monitoring, and geological monitoring.

Key features

● Supports full-band GNSS four-system signals

● High antenna gain, good satellite reception at low elevation angles

● A stable phase center ensures sub-millimeter positioning accuracy.

● It has strong anti-interference capabilities and can withstand harsh working environments.

● Reliable structure, with an IP67 protection rating.

Tracking in complex environments

The antenna unit features high gain and wide beam pattern, ensuring strong signal reception even at low elevation angles. It also guarantees rapid satellite lock-on and stable GNSS navigation signal output even in complex environments with obstructions, such as forests or building obstructions.

High structural reliability

The outer casing is made of fiberglass composite material, ensuring a robust and reliable structure. Multiple protective designs achieve an IP67 protection rating, shielding the interior from dust, UV radiation, and water. With an MTBF (Mean Time Between Failures) exceeding 30,000 hours, it can operate normally for extended periods under harsh environmental conditions such as high and low temperatures, high humidity, and salt spray.

Strong anti-interference performance

The LNA antenna has excellent out-of-band rejection performance, which can suppress unwanted electromagnetic signals and prevent the receiver from being interfered with by electromagnetic waves from other systems such as power grids, communication base stations, and radio stations, effectively reducing the risk of system loss of lock.
