The Department of Defense, through the Army Contracting Command New Jersey, is conducting a market survey to identify potential sources for engineering support services related to the integration of an Assured Positioning, Navigation, and Timing (APNT) capability with the M119A3 towed howitzer's Honeywell artillery Tactical Advanced Land Inertial Navigator (aTALIN). The objective is to retrofit existing aTALIN units and procure new ones that support the integration of the Government-defined APNT capability, which is crucial for enhancing the howitzer's operational effectiveness by providing accurate positioning and orientation data. Interested vendors are encouraged to submit their capabilities, including a statement of their ability to handle GPS User Equipment and cryptographic keys, along with a Rough Order Magnitude Cost for the required services, by May 2, 2025. For further inquiries, vendors can contact Jayde A. Liuzza or Daniel Rakauskas via email.
