Scientific report. Rijswijk, the Netherlands: TNO Prins Maurits Laboratory. 1999. – 48 р.This report describes the status of the work carried out by the TNO Prins Maurits Laboratory (TNO-PML) for the Royal Netherlands Army (RNIA) under project A95KL410, titled: 'Guidance concepts for indirect fire munitions'. This work is related to the general interest within the military world in extending the range of artillery rocket systems. It is of particular interest to the Royal Netherlands Army who are considering upgrading their existing 30+ km range Multiple Launch Rocket System (MLRS) to a 60 km extended range version. When the range of such a ballistic rocket is upgraded, the effectiveness of these weapons will degenerate if the accuracy in position at impact is not kept at the same level or, preferably, improved. To achieve an improved accuracy, the ballistic rocket must be guided to its target. Two basic forms of guidance can be identified; aerodynamic guidance and guidance using small side-thruster rockets. This report focuses on the latter guidance method.Contents:.
