Precise Laser Measurements of Miniscule Electric Field Sensor Displacements to Determine Upper Atmosphere Properties

Completed TRL 3 (started at 2, targeting 3)

Description

This IRAD develops and tests a laser position sensing concept to provide precise knowledge of the position of electric field spheres at the end of long booms from which information regarding the upper atmosphere properties can be determined, as well as information regarding the sphere position. As part of this development, it also designs and builds a prototype, “stand alone” measurement using 1m deployed “vanes” to measure the winds and neutral density in the mesosphere/lower thermosphere on sounding rockets.

Benefits

This IRAD enables a new measurement technique which provides information regarding (1) positional variations of a physically separated sensor in space and (2) upper atmospheric variations for sensors in near-earth geospace under certain conditions. It is anticipated that this information can be acquired with very small resources (compact, inexpensive laser devices). This device could be used to monitor the displacement of physically separated sensors including a variety of deployables on different spacecraft types, providing valuable engineering and scientific information.

How to get involved

This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
