Key features

VRS-3000

Designed for 115 visual approach chart 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 aging SBU-23/MD1 gyros to meet the needs of today’s military pilots.

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/fixed-wing aircraft, an unmanned aircraft or watercraft, the VRS-4000’s certification to RTCA DO-160D environmentals assures operators they can get the job done.
