Introduction

The GPS1000 is a high-performance survey-grade GNSS antenna designed to deliver exceptional satellite signal tracking and stable high-precision positioning. Supporting full multi-constellation systems—including BeiDou, GPS, GLONASS, and GALILEO—the GPS1000 ensures greater availability, improved accuracy, and stronger reliability in complex environments. Engineered for high-precision surveying, mapping, and geospatial applications, this antenna offers excellent phase center stability and superior multipath suppression, meeting the demands of modern GNSS workflows. Compatible with a wide range of professional GNSS receivers, the GPS1000 is suitable for land surveying, construction measurement, GIS data collection, deformation monitoring, and other field operations where consistent, accurate performance is essential.

Key Features

High Phase Center Stability

GPS1000 features a multi-point feeding deign to achieve greater phase center stability. It effectively improves measurement accuracy and provides better positioning solutions.
Tracking in Challenging Environments

The ability to receive low elevation signals with high gain and wide beam width makes GPS1000 an excellent choice for tracking visible satellites under challenging conditions.
Strong Anti-interference Performance

The antenna LNA features excellent out-of-band rejection performance, which can suppress the electro magnetic interference, providing the stability and reliability of GNSS signals.
Durable, Easy-installation design for Precision Applications

The compact and lightweight design makes GPS1000 highly portable and suitable for outdoor operating in precision applications. Its IP67 protection keeps GPS1000 from dust and water for quite a long time.
