TECHNICAL REQUIREMENTS

Inertial Navigation System

GENERAL: Aberdeen Test Center (ATC) is requesting the procurement of an Inertial Navigation System. The Inertial Navigation System shall provide the means for real-time measuring of weapon pointing angles, rates and accelerations while fire control systems are under test. This is for safety purposes in addition to engineering assessments. Recent technological developments in new state-of-the-art fire control systems require higher accuracy measurement equipment to perform proper system assessments.

The Inertial Navigation System shall meet or exceed the following specifications:

1. Weight < 13lbs.

2. Form Factor, not to exceed: 5.5H x 7.7W x 8.7L inches, excluding mounting flanges and connectors.

3. Measurement communication: RS-422 serial @ 100Hz, minimum update rate.

4. Capable of operating from 18 – 32 volt dc power; 50 watts maximum.

5. Azimuth (heading) accuracy within +/- 65 degrees latitude: better than 0.5 mils RMS, without the use of external antennas.

6. Pitch and roll angle accuracy: better than 0.25 mils RMS, without the use of external antennas.

7. Shall operate over the temperature range of -40 to +70 degrees Celsius.

8. Shall have a demonstrated MTBF of > 50000 hours when hard mounted (i.e. without a shock-mounting tray) to a weapon system on a military vehicle.

9. Shall be capable of self-alignment in less than 20 minutes from power application, requiring no external antennas to do so.

Manuals: Manuals/electronic storage devices containing operating and maintenance instructions and drawings/schematics will be provided, as required.
