Traditional antennas typically support only a single satellite system (such as GPS) and cannot fully utilize the resources of multiple systems like GLONASS, BDS, and Galileo. In complex environments (such as urban canyons and mountainous areas), the insufficient number of visible satellites in a single system can easily lead to positioning interruptions or degraded accuracy, failing to meet the demands of high-precision measurement. Traditional antennas have limited capability to suppress adjacent-frequency interference (such as LTE and Wi-Fi signals). Particularly in scenarios with complex electromagnetic environments, the deterioration in signal quality can result in fluctuations or loss of positioning data, thereby reducing operational efficiency.

Solution

The Huayuen Corporation external high-precision surveying antenna is a GNSS full-frequency external surveying antenna that covers GPS, GLONASS, BDS, and Galileo systems. It meets the current demands for multi-system compatibility and high-precision measurement in GNSS surveying equipment, making it widely applicable in fields such as geodetic surveying and earthquake monitoring.

Cases

Geodetic surveying

The external high-precision surveying antenna from Huayuen Corporation significantly enhances the number of visible satellites in complex terrains by supporting full-frequency signal reception across GPS, GLONASS, BDS, and Galileo systems. Particularly in obstructed environments such as urban canyons and mountainous areas, the multi-system combined positioning reduces the risk of signal interruption, ensuring continuous and stable operations for geodetic surveying tasks requiring millimeter-level precision, such as topographic mapping and engineering staking-out.

Earthquake monitoring

Earthquake monitoring requires capturing minute surface deformations (on the millimeter scale), imposing extremely high demands on the stability and long-term reliability of the antenna's phase center. Huayun Shikong's antenna controls phase center errors within ±2mm through advanced technology and employs high-rigidity materials along with a sealed design. This ensures negligible phase center displacement under extreme conditions such as vibration and temperature variations, thereby guaranteeing the long-term consistency of deformation monitoring data.

Other surveying and mapping

Its compact structure and magnetic mounting method are compatible with portable devices such as drones and handheld RTK systems. Combined with intelligent low-power technology, it extends field endurance, meeting the dual demands of efficiency and precision in large-scale topographic surveying.
