Rugged High Accuracy INS sensor Integrated Navigation System for Unmanned Aircraft GINS300


Product Description

GINS300 GNSS/INS Integrated Navigation System adopts high precision MEMS inertial components and integrates GPS/BD single frequency dual-mode satellite navigation system. It is a high-performance, GNSS-Aided Inertial Navigation System (GNSS/INS) that combines micro inertial sensors and a high- sensitivity embedded Global Navigation Satellite System

(GNSS) receiver for use in a wide range of industrial grade applications, such as unmanned vehicle navigation, robotic control, platform stabilization, motion tracking and analysis, vehicle health monitoring, and device aiming.

GINS300 adopts the combination of sensors, environmental compensation, and dual on-board processing with an Extended Kalman Filter (EKF), which make it perform well in a wide variety of applications that require low noise, drift, gain, and offset errors. Uncertainty monitoring, scale factor estimation, and bias estimation outputs are available, and settings for sensor filtering, sensor noise, sensor bias, and more offer many adjustments for specific

application needs.

FAQ

What is GNSS/INS Integration Strategies?

Several approaches can be used to integrate GNSS and INS systems, differing by the “depth” of the interaction and for the shared information between the systems.

The more common strategies are listed below :

-· Uncoupled Integration

-· Loosely Coupled Integration

-· Tightly Coupled Integration

-· Deep or Ultra-Tight Integration

In the Uncoupled approach, the systems work independently providing two distinct navigation solutions; usually GNSS one is considered more accurate and is adopted when available as system solution. Moreover GNSS solution is used to correct (or reset) the INS solution, but without estimating the causes of the sensor drift (as happens in the other integration approaches). In absence of GNSS data the system solution is entirely supplied by the inertial sensor, which tends to drift rapidly according to its grade. For this limitation the Uncoupled strategy is not commonly used.

The Loosely and Tightly Coupled strategies are the more common integration techniques and are implemented in this research; detailed information on them are in the next sections.

In the Loosely Coupled approach the GNSS solution is merged with the inertial based information to obtain the final output of the integrated system, while in the Tightly approach the integration is “deeper”, because the GNSS raw measurements are directly combined with the INS information in a suitable filter.

In the Ultra-Tight integration the GNSS and INS devices no longer work as independent systems, GNSS measurements are used to estimate INS errors and INS measurements to aid GNSS receiver tracking loops; this integration is clearly at deep level and requires access to receiver‟s firmware and so is usually implemented by receiver manufacturers or with software receivers (Petovello 2003, Gautier and Parkinson 2003).
