Septentrio AsteRx2i HDC


Septentrio’s AsteRx2i HDC receiver handles GNSS and IMU measurements to calculate high-quality integrated positions. The integrated solution supporting various IMU grades shows position data up to 50 Hz in addition to attitude and heading information. Various other measurements calculate raw data, acceleration, position velocity and time.

This dual-frequency GLONASS/GPS receiver delivers accurate centimeter-level positioning in signal-weak, shadowed areas where GNSS-only units fail. Furthermore, altitude data for pitch, roll and heading are enumerated.

The AsteRx2i HDC receiver consumes low power. It comes in a compact waterproof plastic housing. Just one cable serves power and communication between receiver and IMU. Thus integration is flexible and easy.

The integrator’s work is aided by a powerful command language, several output messages and formats and serial/USB interfaces. GUI RxControl is used for configuration, logging and remote control. RxControl is compatible with Windows and Linux platforms plus WindowsMobile PDA platforms.
