SkyBee Constellation
SkyBee Constellation
Constellr's operational satellite constellation for thermal intelligence. SkyBee satellites capture global land surface temperatures at 30-metre native resolution (processed to 10 m), with absolute accuracy of 1.0-1.5 K and a thermal sensitivity below 0.15 K capable of detecting subtle operational changes. The constellation operates day and night with a current average revisit of 1.5 days, with sub-daily revisit planned for priority regions. Customers access data and tasking through a Constellation-as-a-Service model without needing to own any space infrastructure.
