About this file
This is a Solicitation Questions and Answers document clarifying requirements for a Track Ball Controller procurement.
The government seeks a 2-axis force proportional tracking ball as a Form, Fit, and Function replacement for legacy Bokam tracking sticks previously supplied by L3 Brashear for the DOAMS (Dynamic Object and Attitude Management System) and KTM (Kinetic Tracking Mount) systems. The unit must feature a half-hemisphere ball control interface (not an aircraft-style joystick handle) with USB physical connectivity and Human Interface Device (HID) software interface compatibility. No National Stock Number is currently assigned. The controller must support dual-use mounting: a free-standing base for standalone operation and the capability to mount to flat surfaces for future integration into a fixed console. The unit should be easily removable from the base to accommodate eventual installation into a permanent console. The tracking ball must be compatible with L3 Brashear mobile Kinetic Tracking Mounts and DOAMS base control software. The document clarifies that 6-axis capability is not required, despite the device sometimes being referred to as a "space mouse" in CAD environments. OEM documentation for current tracking systems is limited, necessitating a contractor capable of developing a compatible replacement based on form, fit, and function equivalency rather than original part specifications.

Track Ball Controller - Solicitation Q&A
BLUF: This Q&A clarifies that the requirement is for a 2-axis force proportional tracking ball with a USB HID interface, compatible with legacy L3 Brashear systems, requiring both flat-surface and free-standing mounting capabilities.
Q&A Summary
# Question Answer
1 Does the requirement specify a standard trackball or a traditional computer mouse?
The requirement is for a 2-axis force proportional tracking stick/ball. While sometimes referred to in CAD environments as a "space mouse," we do not require 6-axis capability. The control interface should be a half-hemisphere "ball" rather than an aircraft-style joystick handle.
2 Is there a specific controller or housing that these trackballs must be installed into?
There is currently no fixed console for installation; therefore, the unit must be versatile. It must be capable of mounting to a flat surface and must be provided with a free-standing base for standalone use. The unit should be easily removable from the base for future integration into a fixed console.
3 Is there a specific Part Number (PN) or National Stock Number (NSN) available for this solicitation?
No NSN is currently assigned, and OEM documentation for the current tracking systems is limited. The objective is a Form, Fit, and Function (FFF) replacement for the Bokam tracking stick (previously provided by L3 Brashear for the DOAMS system). The new unit must utilize a USB physical interface with a Human Interface Device (HID) software interface. This configuration is required for compatibility with L3 Brashear mobile Kinetic Tracking Mounts (KTMs) and DOAMS base control software.
