Each EPSILON series product has a new, miniature, high-performance, factory-calibrated IMU core,magnetometer and one or two RTK receivers, using external access or self-built network RTCM data stream input,The whole system has the same inertial navigation system, which outputs high-precision PVT navigation data.
EPSILON-A is an IMU and AHRS;
EPSILON-E supports an integrated navigation system with external GNSS and other auxiliary sources;
EPSILON-N has a built-in single-antenna L1/L2 dual-frequency GNSS receiver, providing a combined positioning accuracy of about 1m;
EPSILON-D The built-in dual-antenna differential GNSS can provide centimeter-level positioning and dual-antenna lateral function;
EPSILON-D4G is an upgrade of the D version, which can connect to the network NTRIP base station through the built-in 4G device to obtain differential correction data, and has the network remote upgrade function.

Characteristics:

The Epsilon family of sensors includes two independent triaxial gyroscopes, two triaxial accelerometers, triaxial magnetometer arrays, barometers, and thermometers with a powerful SPKF, and a set of Tight integrated navigation algorithms, up to 1000Hz sensor sampling frequency and cone and row motion compensation, online estimation of sensor errors, identification of outliers and measurement anomalies and isolation of faults,structured magnetic field detection and compensation, With anti-magnetic interference ability.
Our algorithm provides high-precision position, which can be easily connected to external vision, sonar/radar and other speed, position, and heading auxiliary equipment for integrated navigation. Users of Epsilon series products can independently configure the built-in dynamic model of the system, and adjust parameters through the interface software to improve the accuracy and stability of navigation.
