MARNAV Block 2 Vendor Demonstrations

NOTE: The Response Date has been updated to 9 May 2025. The Marine Corps’ Mounted Assured Resilient Navigation (MARNAV) Program is the Marine Corps Systems Command (MCSC) lead acquisition effort to field modernized PNT capabilities to host platforms. This program will incorporate an M-Code GPS capability along with additional PNT enablers/alternatives to provide a robust Navigation Warfare (NAVWAR) compliant capability to the warfighters.

The MARNAV Program is divided into two Blocks, with the Block 1 requirements being met by the procurement and fielding of the Army’s Mounted Assured PNT System (MAPS) Gen II. Although subject to change, the current Acquisition Strategy to fulfill the Block 2 requirements is to conduct a full and open competition resulting in the award of a single Indefinite Delivery, Indefinite Quantity (IDIQ) contract.

The Government and the winning vendor may then enter the Engineering and Manufacturing Development (EMD) Phase of the program, and that contractual relationship may continue into system fielding and sustainment. This RFI is being released to solicit vendors who can demonstrate a direct factor replacement for the Defense Advances GPS Receiver (DAGR).
