Arachnida II WMS

The Arachnida II is based on the very successful Arachnida I system, of which 800 are currently in service worldwide, with the SELEX GALILEO FIN3110 inertial navigation unit as primary sensor. The FIN3110 is also an essential part of the SELEX GALILEO LINAPS Artillery Pointing System.

The system is based on Military of the Shelf (MOTS) computers. A 12 inch screen is used for the gunner/commander and a 8 inch display as a Driver Navigation Display (DND). Denel has retained the FIN3110 as primary sensor due to its excellent service history.

Arachnida II system has Sun-Readable colour touch screens and is suitable for mounting on Self Propelled Artillery, Towed Artillery, Mounted Guns, Multiple Rocket Launchers and reconnaissance vehicles. It navigates the Gun or Launcher accurately on a map background, with or without GPS, and therefore completely eliminates any survey procedures. The system provides for full on-board autonomous ballistic calculations and for receiving fire orders via radio data link. Gun Laying can be done accurately to within 1 mil RMS, while offsets for direct firing are calculated automatically. The new system can also include the function of fully automatic gun pointing with the required upgrades to the Gun Control System.
