| Description | Tomorrow.io is developing two demonstration satellites, Tomorrow-R1 and Tomorrow-R2, to test a radar payload on orbit, work through calibration and validation of the instrument, and provide sample data for analysis. The two satellites are identical small ESPA-class satellites, approximately 75kg in mass, and approximately 50 cm x 50 cm x 100 m in size. The payload is being developed by Tomorrow.io, and the spacecraft bus is being developed by Astro Digital. The spacecraft will have full functionally to cease emission upon command. The payload is a Ka-band (35.75 GHz) weather radar that will operate between 35.5 and 36.0 GHz in a monostatic configuration. The radar uses volume backscatter to profile precipitation vertically throughout the atmosphere and uses scatterometry to measure parameters of the ocean surface. The radar is pulse-to-pulse reconfigurable on-orbit, and thus can utilize a variety of underlying sampling techniques and waveforms. The sampling resolution of the radar is approximately 5 km x 5 km horizontally, and 250 m vertically. The radar utilizes a 1.2 m fixed parabolic cassegrain antenna. |
