In conclusion, the requested supplies or services represent the minimum requirements of the government.

Describe in detail why only this source can furnish the requirements to the exclusion of other sources.

(what specific characteristics of the supplies or services limit the availability to a sole source (e.g., unique features, function of the item, etc.)?)

The Doppler velocity loggers are direct replacements. They must be compatible with existing systems. While there are other companies that sell Doppler velocity loggers, none meet the required frequency, size requirements, and have a dedicated altimeter.

☒ The supplies or services must be compatible in all aspects (form, fit and function) with existing systems presently installed/performing. Describe the equipment/function you have now and how the new item/service must coordinate, connect, or interface with the existing system.

The specified hardware interfaces with pre-existing, onsite software and hardware systems. The specified hardware directly interfaces with acoustic doppler current profilers (ADCP) and their associated dual antenna navigation systems as well as provided deck box interfaces. The specified hardware is being

Source Selection Information – See FAR 2.101 and 3.104 purchased to augment the capabilities provided by the ADCP and dual antenna navigation systems, a directly compatible (without modification) doppler velocity logging (DVL) capability.

☐ A patent, copyright or proprietary data limits competition.

☒ These are "direct replacement" parts/components for existing equipment.

The purchase of an alternative product will require (1) the purchase of a different ADCP and dual antenna navigation system, (2) retrofits to the small boat on which these systems are mounted. The design, implementation, and support required for an alternative product will require additional financial support and significant personal hours that are outside of the near-term requirements for this project. Purchase of an alternative system will delay deliverable timelines negatively impacting research and project-based-learning objectives.
