Inertial Navigation Unit (INU) for the Location and Azimuth Determining System (LADS)

1. INTRODUCTION

Project Manager for Combat Ammunition Systems (PM CAS) is conducting a market survey to identify potential sources capable of providing an Inertial Navigation Unit (INU) for the Location and Azimuth Determining System (LADS). This Sources Sought Notice is for informational purposes only and is not a request for proposals. The information received will be used to assess the availability of qualified vendors and inform the development of a future acquisition strategy.

2. BACKGROUND

The LADS is designed to provide users with increased accuracy in position, location, and navigation. The INU is a critical Line Replaceable Unit (LRU) within the LADS, determining position (latitude, longitude, and altitude) and attitude (azimuth, pitch and roll). The INU will integrate with a Vehicle Motion Sensor (VMS) and utilize an embedded Global Positioning System (GPS) receiver, while maintaining functionality in GPS-denied environments.

3. INFORMATION REQUESTED

This SSN seeks information regarding the availability of INU systems that meet or exceed the requirements outlined in this document. Respondents are requested to provide the following information. Please be as specific as possible.

3.1        Company Information:

• Company Name
• Address
• Point of Contact (Name, Title, Email, Phone Number)
• Company Size (Number of Employees, Annual Revenue)
• Cage Code

3.2        Capability Information

a. INU System 

• Do you offer an INU system that meets or exceeds all of the following performance requirements? (Yes/No)
  • Minimum horizontal position CEP: 4m
  • Heading pointing accuracy: ≤0.40 mils RMS (+/- 65° latitude)
  • Maximum static alignment time: 20 minutes
  • Maximum dynamic alignment time: 16 minutes
  • Typical alignment time (28° latitude): 5.5 minutes or less
  • Two-position marking function from a vehicle
  • Azimuth accuracy PE: 0.4 mils on 2 position azimuth lines from 100 meters to 400 meters in length (as defined below)
• Definitions (for Azimuth Accuracy):
  • PE is the equally likely deviation (50 percent probability) of a set of linear measurements about the true (reference) value. PE = 0.6745 x RMSx
  • RMS error is the square root of the mean of the sum of the squared errors, relative to the reference value(s), for all measurements in the sample population. RMS_x=√(∑_(i=1)^N▒X_i^2 )/N where N is the total number of measurements, and Xi = mi-Mi.
• If your firm offers an INU System meeting or exceeding the above stated performance requirements, please provide the following information: 
  • Model Number
  • Brief Description of the System
  • Data Sheet Highlighting the following Key Performance Characteristics:
    • CEP: 4m
    • Heading Accuracy: ≤0.40 mils RMS
    • Static Alignment Time: ≤20 minutes
    • Dynamic Alignment Time: ≤16 minutes
    • Typical Alignment Time (28° latitude): ≤5.5 minutes
    • Weight: <16.2 pounds
    • Power Requirement: 18-32 Vdc, <30 watts
    • Form Factor: Approximately 5.65 H x 7.12 W x 10.3 L inches (excluding
    • feet/flanges) or 5.65 H x 9.0 W x 11.34 L inches (including battery/feet)

b. Software: 

• Describe your software update process and support capabilities.
• Can your system be upgraded to support future M-Code GPS Receiver Cards? (Yes/No)

c. Production Capacity:

• What is your standard warranty period for INU systems?
• Describe your repair capabilities, including turnaround time and OEM-level support.
• Can you meet the 30-day Repair Turn-Around Time requirement? (Yes/No)

e. Configuration Management & Quality:

• Describe your Configuration Management process, referencing SAE ANSI/EIA-649.
• Is your Quality Management System certified to ISO 9001 or equivalent? (Yes/No)

f. Obsolescence Management:

• Describe how your firm mitigates obsolescence.

g. Unique Item Identification (UII):

• Are you familiar with and capable of complying with DFARS 252.211-7003 and AR 700-145 regarding Item Unique Identification? (Yes/No)

h. Packaging:

• Are you capable of packaging the INU in accordance with MIL-STD-2073-1 and marking in accordance with MIL-STD-129? (Yes/No)

3.3        Rough Order of Magnitude (ROM) Cost:

• Provide a ROM cost estimate for a single INU system, including integration of a Government-Furnished SAASM card.
• Provide a ROM cost estimate for a single software update.
• Provide a ROM cost estimate for a full repair (OEM level).
• If range pricing is available for the INU System and/or repairs, please provide pricing information.

4. GOVERNMENT FURNISHED MATERIAL (GFM)

Assume the Government will provide one (1) MPE-S Type I SAASM 3.2 GPS Receiver Card (SAASM card) per unit as GFM.
