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 reached the target point within few metres of accuracy.
Sigma 40 navigation systems are built around a ring laser gyro
(RLG) inertial core, which guarantees sustained very-high-precision, coupled with a high degree of operational flexibility.
It appears that the spacecraft suffered a double whammy: first the star tracker could not lock onto its correct guide stars, and then a laser gyro
in Stereo B's Inertial Measurement Unit, which senses the craft's orientation, failed and started providing bad data to the attitude-control system.
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.
Based on digital laser gyro
technology with a long optical path, SIGMA 30 reflects SagemOs proven expertise in the production of navigation systems and inertial sensors.
He highlighted the indigenous fibre optic gyro with integrated optic chip, wing laser gyro
for inertial navigation system for guided missiles, handheld thermal imagers, and laser range finders etc.
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.
For this purpose, a high accuracy laser gyro
or rotary encoder can be used.
The upgraded system is dubbed S19 L and uses a laser gyro
and a new guidance processor.
The installation of the systems, known as the LTN-92 Ring Laser Gyro
Inertial Navigation System, or INS, is scheduled to be completed this fall with other installations still being negotiated.
Sierra also added a Litton Guidance and Control LN-93 Ring Laser Gyro
INS, a GEC Miniature Standard Central Air Data Computer, a new angle of attack system, and a video camera/recorder.
Calling on a laser gyro
core, they also feature laser technologies that guarantee sustained high precision, along with operational flexibility.
