Wildfire

In this demonstration, we model, simulate, and analyze a notional satellite mission called Wildfire. This demonstration shows off some of the key features in the Sedaro Satellite Mission Designer module and can serve as a reference when modeling your missions in Sedaro Satellite.

Wildfire

3U CubeSat mission to deliver low-latency thermal imaging of active wildfires

• On-demand tasking of up to 12 imaging targets
• Uplink from Sedaro HQ
• Downlink via laser comms constellation
• Deployed from the ISS
