Beskrivning : The TROPICS constellation will be formulated with four CubeSats in each of three orbital planes with the following launch parameters: equally spaced RAAN ( ±30 km tolerance), 600 km altitude (550 ±50 km tolerance), 30° inclination ( ±3° tolerance). These mission parameters will meet science requirements should the threshold number of CubeSats (eight) be implemented. Analyses have shown orbit lifetime of 9 years, well over the expected mission lifetime of one year and well in advance of the 25-year de-orbit requirement. This configuration yields 30-minute median revisit rates with average spatial resolution better than precipitation and all-weather temperature and humidity (PATH) requirements, all from a low-cost, low-risk CubeSat constellation platform.
