Abstract: |
The objective of this SBIR program is to design and develop high performance and jam-resistant GPS/INS navigation technologies with the goal of optimizing the size, weight and power (SWaP) of the system for use in air-dropped Precision Guided Munitions (PGMs) and small Unmanned Air Systems (UAS) operating in GPS challenged environments. A gun-hardened variant of DIGIT system can support NAVSEA gun-launched PGMs.
The primary components of the proposed Mayflower DIGIT system encompasses a military SAASM GPS receiver, a MEMS IMU, both SWaP-optimized for PGM applications, and a software algorithm for Ultra-Tight Coupling (UTC) of GPS with IMU. The DIGIT system will, in its final form factor, be packaged in a 30 mm cylindrical form factor (less than 2 inches in height) with electrical/mechanical interfaces and specifications conforming to the Joint Common GPS (JC-GPS) Interface Control Document (ICD) and Specifications.
In the Phase I Program, Mayflower will perform a detailed trade-off of various components of the DIGIT system, and develop preliminary design of the system. The performance of the DIGIT technology will be demonstrated on a prototype system in the Phase II program using the Mayflower NavAssurer SAASM GPS receiver, a small MEMS IMU and an ultra-tightly coupled GPS/INS algorithm. Mayflower will repackage the DIGIT system in a 30 mm cylindrical form factor in a follow-on Phase III program.

Benefits: |
The proposed technology development will result in highly SWAP-C optimized Deeply Integrated GPS/INS system that is suitable for use in the Navy PGMs and small UAS platforms and will provide robust navigation in jamming and other GPS degraded/denied environments. |
