Pixxel launched two primary tech demo satellites: D2 and Shakuntala. Each satellite has distinct capabilities tailored for different spectral ranges. They were aimed to have a coarser spatial resolution and prototype data quality—it's more an 'art of the possible' thing; our Firefly commercial data are significantly more detailed and of high quality.
The tech demo 4 is a SWIR prototype satellite that is to be launched soon.
