Latest Patents

One of Geisler's latest patents is titled "Multi-spatial mode enabled PAT and AO terminal architecture for free-space optical communications." This invention addresses the limitations of conventional pointing, acquisition, and tracking (PAT) systems that often divert energy from the communications receiver, thereby reducing signal-to-noise ratio (SNR) and sensitivity. Geisler's innovative approach allows for tilt angle determination without energy diversion, utilizing a passive mode converter to track power in different spatial modes. This advancement significantly improves the efficiency of free-space optical communications.

Another notable patent is "Ground terminal design for high rate direct to earth optical communications." This invention tackles the challenges faced in direct-to-Earth laser communications between spacecraft and ground terminals. Geisler's design enables high data rates that can efficiently empty high-capacity on-board buffers of spacecraft in a short transmission window. The system employs a network of compact optical ground terminals that receive and demodulate optical data transmissions from multiple orbiting satellites, ensuring reliable communication even in adverse weather conditions.
