A -- INERTIAL NAVIGATION/WEAPON POINTING SUBSYSTEM (INS) FOR THE ADVANCED TOWED CANNON SYSTEM (ATCAS) SOL DAAE30-96-R-0001 DUE 022996 POC Mr. Robert McMinn, Contract Specialist, 201-724-3504, email-rmcminn; Gregory L. Gorman, Contracting Officer, 201-724-3271. The U. S. Army Armament Research, Development and Engineering Center requires an inertial navigation/weapon pointing subsystem (INS) as a part of the Automated Fire Control System (AFCS) for the Advanced Towed Cannon System (ATCAS). A draft solicitation will be issued for this requirement on or about 16 February 1996. Industry comments will be accepted on or before 29 February 1996. The INS shall be a self contained state-of-the-art system capable of self locating to an accuracy of not more than 10 meters horizontal Circular Error Probable (CEP) and not more than 10 meters vertical Probable Error for all combat conditions. The INS shall not require stopping too maintain the required accuracy. The INS may use odometer speed and/or Global Positioning System (GPS) signals to enhance accuracy. However, it shall not be totally dependent upon GPS signals to compute position information of the required accuracy. If required, the GPS receiver shall be the Army's Precision Lightweight GPS Receiver (PLGR),. or any receiver having the approval of the GPS Joint Program Office. The INS shall also determine the cant compensated elevation and azimuth of the ATCAS cannon to an accuracy of 0.5 mils Standard Deviation (SD) and 1.0 mil SD respectively. All position and pointing data shall be updated continuously and the information shall be communicated to the AFCS in real - time. The INS shall operate from a standard 28 Volt d.c. military electrical system, with a power consumption not to exceed 100 watts. The INS shall fully align itself to the required accuracy in less than 15 minutes from a cold-start. It shall also have the ability to perform a rapid alignment to an accuracy of less than 5 mils within 3 minutes, and reinstate its last stored heading within 30 seconds, both from cold-start conditions. The INS shall be able to withstand the shock and vibration and other environmental conditions associated with firing, towing, and general operations for the Army's M198 155MM Howitzer. A formal RFP will be issued on or about 15 March 1996. Government and industry comments regarding the draft solicitation can be sent to: U.S. Army ARDEC, ATTN: AMSTA-AR-PCW-A, Mr. Robert McMinn, Building 10, Picatinny Arsenal, New Jersey 07806-5000.
