PathFinder Digital was awarded a contract by the National Aeronautics and Space Administration (NASA) to study the feasibility of developing a transportable research and test platform to facilitate the design of Free Space Optic (FSO) satellite networks. The study focuses on the development of Optical Ground Stations (OGS) and their interoperability to Optical Space Terminals (OST). The study also focuses on the development of atmospheric mitigation techniques such as site diversity, cognitive networking and hybrid lasercom/RF networks. The transportable test platform would provide both US industry and the US Government the tools necessary to refine standards and facilitate FSO development. "Laser communications is likely to be a disruptive technology in the field of satellite communications, especially regarding its use as a backbone for space to ground communications with GEO, MEO and LEO networks. PathFinder is proud to be at the forefront of free space optic communications. Our growing expertise in laser/optical communications is a great supplement to our extensive experience in RF communications. We look forward to continuing our work in this field with NASA, other US Government agencies and industry," said Roger McGarrahan, CEO of PathFinder Digital LLC.
NASA Funds Development of Novel Diffractive Solar Sails Rochester NY (SPX) Apr 29, 2019 Scientists have been floating designs for solar sails to propel spacecraft for decades, but a new approach being developed by a Rochester Institute of Technology professor could be the key to helping spacecraft photograph the poles of the Sun for the first time. NASA announced it is providing RIT Professor Grover Swartzlander a Phase II award through its NASA Innovative Advanced Concepts (NIAC) program to explore the feasibility of diffractive solar sails over the next two years.
