Inertial navigation

The inertial navigation system and airborne data annotation system of AOSS II provide position references that are superimposed on all data products. The four sensors and position reference system are integrated by means of a software-controlled operator console that requires only one operator. Color and black-and-white TV monitors display information from the sensors. Under low-contrast conditions, false color enhancement is used to facilitate interpretation. 

There are inertial navigation systems used on submarines and space vehicles that determine the acceleration as a function of time and perform two numerical integrations in order to determine the position of the vehicle. 

Description of the Process Controiier (the iNU) The Inertial Navigation Unit (INU) has two parts (figure B.2) (1) the Guidance,Navigation, and Control System (the Flight Control Software or PCS) and (2) an Inertial Measurement System... 

The accident report does not explore whether the PCS software could have included sanity checks on the roll rate or vehicle behavior to detect that incorrect roll rates were being provided by the IMS. Even if the PCS did detect it was getting anomalous roll rates, there may not have been any recovery or fail-safe behavior that could have been designed into the system. Without more information about the Centaur control requirements and design, it is not possible to speculate about whether the Inertial Navigation Unit software (the IMS and PCS) might have been designed to be fault tolerant with respect to filter constant errors. 

It is often useful to describe (or allocate in a separate column) the flight/mission phase that the aircraft is in when the failure occurs. For example, a failure of the Inertial Navigation System (INS) during cruise at flight level (FL) 300 will have a vastly different effect compared with the same failure occurring during final approach under IFR conditions ...

Inertial navigation systems (Charles Stark Draper) Draper s inertial navigation system (INS) is designed to determine the current position of a ship or plane based on the initial location and acceleration. 

In contrast to land surveys that are mostly static, bathymetric measurements are dynamic as the ship is saihng during the survey. For a bathymetric survey, it is highly recommended that the orientation and the positions of all sensors are well known. If this is not the case, significant errors in depth and position will occur. Sonar systems derive their positional information from external navigation systems. These are typically a combination of GPS units and inertial navigation systems (INS = motion sensor and computer based navigation system). 

The special features of these cells are high reliability (belter than 0.7 x 10 ), indication of end of life by a second plateau voltage, a discharge capability up to lOOpA, and low internal impedance. Applications of lithium-silver chromate cells include cardiac stimulators and other human implantable devices, high reliability memoiy protection for inertial navigation systems, and RAM back-up pourer sources. 

These batteries are used in cardiac stimulators, other human implantable devices, high-reliability memory protection, inertial navigation systems and RAM backup power sources. 

Aeeelerometers are inertial sensors used in inertial navigation systems to determine the accelerations of the vehicle. Additionally, an inclinometer is essential to maintain the stability and linearity of the vehicle.
