Attitude Determination System

Overview

A customer came to FSL as they required a system that they could use to position three microphones and know the relative distances, heading and pitch between all three. They also required that they could change the display to match either TRUE or any GRID projection from a worldwide selection. Another requiremnt was to ensure that the system was weather proof and had a method of remotely viewing the data in real-time.

Summary

The CPUPak was used as a foundation for the solution. Three OEM4 receivers were combined inside the CPUPak housing and internally connected to pass corrections from the master to the rovers. Waypoints RTKNav solution was used to generate the attitude data between the three antenna. The system was built into a Pelicase and all the vital connections were wired to the outside of the case for functionality without requiring to open the lid.

The data was displayed by either connecting a monitor to the CPUPak or remotely using a PDA. We develop specific software for viewing and controlling the system. The NAVPak-ADS software includes a worldwide geodetic suite (external BlueMarble Dll) to provide the functionality to transform between coordinate systems in real-time. Changing the geodetic suite could not be done from the PDA, the user was required to connect a keyboard, mouse and keyboard to the CPUPak for operation. This restriction was due to the BlueMarble Dll not being compatible for Windows CE.

This system has now been replaced by the MICROpod-ATT system.
