The Department of Defense, specifically the Marine Corps Systems Command (MCSC), is seeking industry input through a Request for Information (RFI) regarding the modernization of the Global Positioning System-Survey (GPS-S). The objective is to gather capabilities and experiences from potential contractors to enhance the GPS-S, which is crucial for providing accurate survey information to Marine Artillery Sensor Sections in diverse and challenging terrains. Key modernization efforts include integrating M-code GPS, ensuring compatibility with Windows 11-compliant software, facilitating communication between stations via AN/PRC-163 radio, and upgrading the handheld controller. Interested parties must submit their responses, limited to 15 pages, by December 24, 2025, and can direct inquiries to Melanie Williams at melanie.willaims.civ@usmc.mil.
