Free Space Optical Communications for Nanosats

We will develop this project in 3 stages: modeling, lab demo, and field testing. Modeling: We will create a model of the gray scale, in contrast to binary, data transmission problem. We will model the MRR contrast response versus voltages operation speed. We will include scintillation and atmosphere turbulence modeling for different air masses (i.e. atmosphere thickness crossed at a given angle). The outcome will be the optimal operational parameters.

Communications with nanosats, and in general, with any kind of spacecraft that does not have a high-gain directional antenna and associated pointing and power-generating capabilities, is limited to low data communication rates, hindering the quantity of information that can be downloaded. Enabling data intensive applications for nanosats, such as imaging, through the use of a power-efficient technology with minimal pointing requirements (tens of degrees), is potentially a game-changer

This is early/mid-stage (TRL 4) — 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.
