MIL-STD

INTRODUCTION

1.   The United States Military Standard (MIL-STD) ensures that products meet certain minimum requirements and standards of reliability established by the U.S. Department of Defense.

2.   The standard is also used by non-defense government organizations or industries as a way of showing that their products meet the criteria.

3.   The UAV Navigation VECTOR autopilot has achieved the following MIL-STD certifications:

MIL-STD-461F

4.   The MIL-STD-461 includes all the requirements for the control of Electromagnetic Interference (EMI) characteristics of subsystems and equipment.

5.   This standard describes the different tests needed to guarantee Electromagnetic Compatibility (EMC) and to analyze the EMI of an equipment.

6.   These tests are applied to electronic, electrical and electromechanical equipment and subsystems. The items should have the following features: electronic enclosures that are no larger than an equipment rack, electrical interconnections that are discrete, wiring harnesses between enclosures and power inputs derived from prime power sources.

MIL-STD-810F

7.   The MIL-STD-810 standard is related to Environmental Engineering Considerations and laboratory testing.

8.   This standard establishes the environmental test conditions (vibration, acceleration, humidity, rain, temperature etc.) that the equipment may be subject to throughout its service life. MIL-STD-810 includes environmental stress sequences, durations and cycles. The methods described in the standard aim to imitate the influences that enviromental stresses that the equipment is likely to be subject to during military applications.

9.   These tests are also used to show whether an equipment is able to comply with a technical requirement stated in a commercial contract, often by a customer who is used to working with a military end user. The results of such tests are analysed to identify any deficiencies or defects in the equipment design. An equipment may be redesigned if a deficiency is found in order to meet the standard. In the case of the VECTOR, no redesign work was required, which itself is a validation of UAV Navigation's Quality procedures and design philosophy.
