Emcore Corporation has launched the EN-2000 to the Emcore-Orion series of micro-inertial navigation (MINAV) systems.

The new EN-2000 will represent the pinnacle of performance in Emcore navigation systems, and realizes the company’s vision of a closed-loop, solid-state design that will deliver higher performance at lower cost than traditional RLG (ring laser gyroscope) navigation systems.

The EN-2000 expands Emcore’s navigation systems line that also includes the EN-1000 introduced in 2017. The Emcore-Orion series of inertial navigation system (INS) are designed for use in a broad range of defense, aviation and aeronautics applications.

The unit was introduced at the Paris Air Show, held June 17-20 at the Parc des Expositions Paris-le Bourget in Hall 6, Stand #C65.

Today, there is an ever-increasing premium being placed on modern navigation systems for improved size, weight and power (SWaP). Traditional RLG navigation systems placed a premium on accuracy and performance, but not SWaP. Typical RLG and FOG systems are large and heavy, ranging in volume from 330 in3 to 540 in3, weighing 13 to 22 pounds with power requirements of 25 to 38 watts.

Many modern weapon systems are now remotely operated, unmanned or man-portable and may need to operate where GPS is unavailable or denied. The compact EN-2000 is designed for these applications. It puts a premium on accuracy and performance, but also on smaller size, less weight and lower power consumption.

The new Emcore-Orion EN-2000 MINAV is a three-axis design using the company’s proprietary, next-generation solid-state optical transceiver with advanced integrated optics, combined with all new field programmable gate array (FPGA) electronics to deliver stand-alone aircraft-grade navigator performance at one-third the SWaP of legacy or competing systems.

The EN-2000 model comes in two standard versions, an IMU version and a standalone INS configuration. The INS version can gyrocompass to less than 0.7 milliradians and maintain near-GPS-level positional accuracy without the use of a GPS receiver. This makes it suitable for use in GPS-denied environments.

To provide customers with additional flexibility, the unit is also capable of being aided by an external GPS for applications where needed.

The Emcore-Orion EN-2000 is compact and lightweight, weighing less than 7 pounds, with very low power consumption of 10 watts. It can deliver twice the performance of the EN-1000 with the same form factor.

The low SWaP of the EN-2000 makes it a suitable inertial navigation system for unmanned aerial vehicles (UAVs), unmanned underwater vehicles (UUVs), unmanned ground vehicles (UGVs), manned aircraft, rotorcraft and dismounted soldier applications.

“With the introduction of the EN-2000, Emcore can now offer class-leading performance at a fraction of the size, weight and power of competing systems with increased reliability,” said David Faulkner, Emcore vice president and general manager of aerospace and defense. “Emcore’s goal of a true full navigation system that can replace older technology navigation systems in UAVs, UUVs, UGVs, manned aircraft and rotorcraft is fully realized with the introduction of the EN-2000.”

“Our Emcore-Orion series micro navigators improve dramatically on the size and cost of navigation and azimuth sensing equipment by utilizing affordable lightweight sensors that reduce overall system weight and increase accuracy,” added K.K. Wong, Sr., director of fiber optic gyro products for Emcore. “The digital interface is also fully programmable at Emcore’s factory enabling it to directly replace competing units.”
