VRS-3000 / 3010 / 4000 Vertical Reference Systems

Product overview

Engineered to outperform and outlast conventional spinning-mass vertical gyroscopes, the L3Harris family of vertical reference systems reduces costly mechanical repairs while providing superior reliability. With software that is qualified to DO-178B Level A, the VRS-3000, VRS-3010 and VRS-4000 are designed to drive primary and secondary flight displays, as well as flight controls (autopilot). And with their multiple output formats, they are compatible with both analog and solid-state attitude indicators.

  • Solid-state performance
  • More reliable operation than mechanical systems
  • Compatibility with manned and unmanned aircraft and watercraft

Key Features

VRS-3000

Designed for 115 VAC platforms, the VRS-3000 replaces gyroscopes such as the SBU-23 and MD-1, utilizing solid-state rate and level sensor technology to provide accurate attitude and rate measurements. When paired with an Air Data Computer, the VRS-3000 is capable of providing attitude, altitude, airspeed, vertical speed and slip/skid information.

 

VRS-3010

The VRS-3010 is designed to outperform the aging, old school SBU-23/MD1 gyros to meet the needs of today’s military pilots. With software that is qualified to DO-178B Level A, the VRS-3010 is designed to drive primary and secondary flight displays, as well as flight controls (autopilot).

 

VRS-4000

In today’s increasingly sophisticated air and sea activities, it’s critical to have reliable reference information at your fingertips when you need it. Whether the application is a rotary- or fixed-wing aircraft, Unmanned Aircraft Systems or watercraft, the VRS-4000’s certification to RTCA DO-160D environmentals assures operators they can get the job done.
