SATELLITES announces plan for multi-sensor weather satellite constellation

(21 Mar 2022) The Tomorrow Companies Inc. ("") announced plans to introduce microwave sounders as an additional sensor to its planned satellite constellation. The addition of microwave sounders to the company's constellation of radar-equipped weather satellites would create the first commercial multi-sensor weather satellite system owned and operated by a private company.

The combined sensing capabilities from radars (active microwave sensors) and sounders (passive microwave sensors) will allow to acquire multiple types of near real-time, global atmospheric data critical to improving weather forecasts. The data, when fed into Tomorrow's proprietary models and its Weather and Climate Security software platform, is expected to enhance the ability of organisations to proactively prepare for and mitigate the business impact of weather. will also offer data-as-a-service to government agencies worldwide. previously announced plans to launch a first-of-its-kind constellation of radar-equipped satellites to collect global precipitation data with hourly revisit rates. Radar provides vital observations of the global water cycle for weather forecasts. Yet, much of the world lacks ground-based radar coverage with virtually no coverage across the oceans, limiting the ability to generate reliable weather alerts.

Augmenting the company's planned satellite constellation with microwave sounders would further improve the global revisit rate for precipitation data and enable the acquisition of additional measurements such as three-dimensional temperature and water vapor profiles at an unprecedented refresh rate. This enhancement is expected to dramatically improve hurricane forecasting, flood alerts and natural disaster management.

Earlier this month, Tomorrow announced the successful completion of a critical design review of its proprietary weather radar satellites with the U.S. Air Force (USAF). Last year the USAF awarded a US$19.3 million contract to to support development of the company's first four weather satellites. The first satellites are expected to launch in late 2022, with a full constellation expected to be in orbit by 2024.
