Abstract: An improved ThinSat constellations is a group of satellites for carrying experimentation and data collection payloads. They are launched and orbit through Low and Very Low Earth Orbit (LEO/VLEO). Thinsats solve complex communication and data retrieval issues with duplex radios, low power transceivers, and high gain tracking ground stations with infrequent and short line-of-sight overpasses. Thinsat modules can be structurally connected to provide improved data collection, workflow, redundancy, and solar/battery power plus drag systems for earlier re-entry. Thinsat includes a pair of thin patch PCB fastened on each side of a frame, power and EPS, a processor, GPS, antennas, wiring harnesses, a radio, solar cells, various sensors, and space for a selected payload. Thinsat is a cost effective means of space research with sensor testing, ground station calibration, and a variety of educational and commercial missions.

Abstract: This is an Improved Radio Communications System called Eyestar. It is a simplex (one way, send or receive) or duplex (two-way, send and receive) Improved Radio Communications System called Eyestar. It provides a solution for quick, low power (0.2 W), reliable beaconing of data from one's satellite. The data is transmitted 24/7 anywhere and anytime with max data rates of 8 Bytes/sec operating continuously. The Simplex and Duplex versions has a Buffer to filter RF output from being damaged; it has a modified the internal firmware to improve broadcast speeds; it provides continuous connectivity for one's satellite in orbit (24/7); the simplex and duplex (they) have worked well in polar and lower inclinations and also for tumbling spacecraft; they need no ground station; they are FCC licensed; and they are less expensive, smaller, and require less power than the other qualified S-band, X-band radios.
