1HOPSat [Hera Systems]
1HOPSAT TD (1st-generation High Optical Performance Satellite Technical Demonstrator) is the prototype satellite of an earth observation constellation by Hera Systems.
The satellite is build to the 12U CubeSat form factor and will test systems for the initial operational constellation of eight 1HOPSat satellites. The satellite contains an imaging telescope payload for recording images and video of customer specified regions of the Earth at 1 meter ground sample distance (GSD). The collected images will be transmitted to Earth through ground stations over a single carrier, OQPSK, X-band radio link. Commanding and telemetry will be implemented with an experimental C-band radio using 802.11n (OFDM) technology. Commanding and telemetry are supplemented with an Iridium short burst data (SBD) radio providing low rate data
During launch, the satellite will be contained in a 12U CubeSat payload dispenser attached to the upper stage of the launch vehicle. The 12U dispenser provides full enclosure of the satellite until deployment in orbit. After deployment and prescribed time delays, antennas will deploy, imaging and communications will begin. There will be no propulsion on the TD spacecraft.
