Real Time Navigator (RTN)

Purpose

Integrated Navigation Systems combine GPS and inertial sensors with sophisticated software to yield extremely accurate locational information. Most systems are designed from the ground up, with proprietary hardware and software.

The Real Time Navigator (RTN) is a generalized software package that allows you to define your own suite of GPS and inertial sensors without having to write custom software. RTN speeds up system development by allowing you to use off-the-self sensors without costly software engineering.

Features

RTN is a flexible software package that can be integrated with any GPS and IMU hardware

Software separate from the Navigation software provides explicit interfaces to any IMU and any GPS

Full Strapdown Inertial Navigation solution at IMU data rate (e.g., 200Hz, WGS-84)

Initial heading and leveling alignment accomplished with Kalman Filter

Built-in in-air alignment capability (re-start)

Navigator and instruments calibrated with Multi-state Kalman filter using GPS observations

UTC event imaging to 1 microsec

Interfaces with user IMU via RS422 port, including data strobe

Interfaces with user GPS via RS232 or RS422 port, including 1PPS data strobe

System Description

RTN software is written with C++ constructs and a unique Publish/Subscribe Class providing easy inter-process communications with alternative hardware suites

Kalman filter tuned to specific user hardware elements

QNX or VxWorks operating systems
