A High Accuracy User Terminal (HAUT/UT) by ANavS is a portable, high-precision GNSS receiver system designed to implement advanced PPP positioning using Galileo High Accuracy Service (HAS) corrections, providing precise real-time position, velocity and time data.

High Accuracy User Terminals use Precise Point Positioning (PPP) with satellite broadcast corrections (e.g., Galileo HAS) so that accurate GNSS positioning can be achieved globally without needing a local reference.

The High Accuracy User Terminal implements Precise Point Positioning (PPP) using satellite correction data from the Galileo High Accuracy Service (HAS). PPP allows high-accuracy GNSS positioning anywhere globally without dependence on local reference stations.

The High Accuracy User Terminal is designed to use Galileo HAS corrections for PPP and can work with multiple constellations such as Galileo and GPS, retrieving corrections via Galileo E6 or Internet Data Distribution (IDD).

High Accuracy User Terminals integrate a multi-frequency, multi-GNSS receiver (capable of E6B signal tracking for HAS), industrial-grade IMU, and a processing unit with interfaces such as PoE, Wi-Fi, USB-C and Bluetooth for configuration and data logging.

Yes. It supports extensive logging of GNSS observations, PPP/HAS corrections, and high-rate solution streams to internal memory in various formats supported by analysis tools.

Yes. The HAUT/UT is portable and includes internal batteries, enabling autonomous operation off grid without external power for several hours.

High Accuracy User Terminals are ideal for high-accuracy GNSS experiments, validation of the Galileo High Accuracy Service, precision positioning applications, scientific research, surveying, and environments where reliable global PPP performance is needed without local infrastructure.

Standard GNSS receivers without HAS or PPP support deliver meter-level accuracy. High Accuracy User Terminals leverage satellite-delivered PPP corrections to achieve significantly improved real-time positioning precision without relying on base stations.

An RTK reference station (like G-ROX) provides local correction data for nearby rovers, while a High Accuracy User Terminal uses global PPP corrections (e.g., via Galileo HAS) to obtain high-accuracy position solutions anywhere without local infrastructure.

The High Accuracy User Terminal is a portable GNSS/PPP receiver system designed to leverage Galileo High Accuracy Service (HAS) corrections for global high-precision positioning. It should be used in applications requiring precise real-time position, velocity and time solutions without local base stations, such as PPP validation, high-accuracy GNSS research and advanced navigation.
