Solid State Vertical Reference System and Electronic Horizontal Situation Indicator

N/Aew solid state designed products have been developed to replace older elctro-mechanical instrumentation. Both the Vertical Reference System (VRS) and the Electronic Horizontal Situation Indicator (EHSI) feature solid state designs and offer improved reliability over electro-mechanical units, enhanced cockpit presentation and additional functionality. The VRS-3000 can be installed in fixed wing aircraft, helicopters, drones, and remotely piloted vehicles. The HIS-3000 was designed to replace electro-mechanical HSIs and was developed for rugged military environments.

The VRS-3000 was designed as a replacement for conventional spinning mass type vertical gyroscopes and utilizes solid state rate and level sensors and provides traditional ARINC 407 synchro information for pitch and roll attitude.

The EHSI-3000 allows for pilot-commanded heading and course inputs on one flat panel 3in ATI Active Matrix Liquid Crystal Display. The system requires +28vdc, weighs less than 3 pounds, interfaces via 1553 multiplex (MUX) bus, and was tested to MIL-STD-810 and MIL-STD-461/462 environmental requirements. The unit features four basic functions for selection among four modes: ILS/TACAN, TACAN, NAV, and ILS/NAV.
