Also bitte Tom wenn ich was sage prüf doch nach ob du nicht vielleicht doch falsch liegt und dann rede, so ersparst du dir einen Fehler und mir ersparst du zeit eine Internet Seite für dich zu finden, oder willst du mich damit ärgern :evil:
Hier was für dich:
"INERTIAL GUIDANCE
Inertial Guidance or Inertial Navigation Systems (‘INS’) use gyroscopes and accelerometers (which detect motion) to calculate changes in relative positions. Wholly independent of any external signals or support, they cannot be jammed or affected by electronic countermeasures.
The disadvantage of INS is its inherent inaccuracy, making it unsuitable for use as the sole guidance system in a cruise missile. Gyro-scopes are subject to errors which accumulate over time - the longer the flight time, the greater the error. The INS fitted to the US Tomahawk drifts by 900 metres per hour. At its cruising speed of 800 km/hr and a distance of 1,600 km, this inertial drift equates to an error of 1,800 metres, necessitating the use of supplementary guidance systems such as Terrain Contour Matching (TERCOM) or GPS.
Whilst gyroscopes used to be sensitive mechanical devices, Ring Laser and Fibre Optic Gyroscopes are becoming increasingly common; the US company Northrop has developed a micro-optic gyro which places an entire INS on a computer chip. Nonetheless, the 10 degree per hour drift claimed for this system is still too high for cruise missile guidance, and any system so equipped would require regular positional updates from external sources such as GPS in order to achieve the accuracy necessary for a precision strike."

Denke jetzt nicht das es wie bei einer CM, nur eine Genauigkeit von 1800m hat, SCUD's fliegen viel kürzer
