Summary: TEHRAN (FNA)- Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light.
The guidance, control and navigation system of the missile is configured around the indigenously designed Ring Laser Gyroscope (RLG) and MEMS based Inertial Navigation System (INS) along with GPS system.
A specific version of the device known as a ring laser interferometer sends beams of light in opposing circular directions, creating a beat frequency rather than fringe shifts when they are combined.
The most accurate ring laser gyro-based inertial navigation system (RINS) and supported by highly reliable redundant micro navigation system (MINGS), ensures the vehicle reaches the target within two-digit accuracy.
It also analyses the market share by gyro technology including ring laser gyro (RLG), fibre optic gyro (FOG), micro-electro-mechanical systems (MEMS), hemispherical resonator gyro (HRG), and vibrating gyro.
Under the contract Northrop Grumman will also manage various products and systems that it supplies, including the WSN Ring Laser Gyro Navigation system, AN/BPS-15/16 Radar Set Weapon system, Steering/Scalable Integrated Bridge System and SPQ-9B radar set items.

The state-of-the-art Ring Laser Gyros based high accuracy INS (INS) and Micro Navigation System (MINGS) complementing each other in redundant mode have been incorporated into the missile system in guidance mode," he added.
The navigation systems, very high accuracy Ring Laser Gyro based Inertial Navigation System ( RINS) and the most modern and accurate Micro Navigation System ( MINS) ensured the missile reach the target point within few meters of accuracy," the release said.
The redundant navigation systems, very high accuracy Ring Laser Gyro based Inertial Navigation System (RINS) and the most modern and accurate Micro Navigation System (MINS) had ensured the missile reach the target point within few meters of accuracy.
Besides its unique Zero-lock gyros, it produces spinning mass gyros, ring laser gyros, fiber-optic gyros, micro electro-mechanical system gyros and hemispheric resonator gyros.
The HG1700 [IMU] was integrated with MEMS gyroscopes from the Draper laboratory, replacing the ring laser clusters.
