        EMCORE-Orion  Series EN-1000/2000 Micro Inertial Navigation Systems                  COMING SOON!
                      TM
        The EMCORE-Orion  series EN-1000/2000, high-precision Micro Inertial Navigation (MINAV)
                       TM
        systems can gyrocompass from approximately 0.8 to 1.2 milliradian depending on the model in
        environments where GPS is unavailable or denied. EMCORE’s advanced FOG INS technology has
        enabled the units to provide performance comparable to traditional RLG INS with 1/3 the SWaP.
        They are designed to provide customers the flexibility to choose the performance level tailored
        to their application. The EN-1000/2000 are also capable of being aided by an external GPS for
        additional flexibility.
