The most successful way for expert payload users to get their mission into operation

Small Satellites are a critical enabling technology for scientific advancement and businesses operating in the growing New Space industry. Although, New Space is entering a period of fragmentation and adaptation, whereby space technology users are unable to fully achieve their mission objectives without themselves becoming satellite bus designers, developers and manufacturers.

Third Planet Orbital develops reliable building blocks for space technology users deliberately focusing on the robustness and trustworthiness of its products. Diverging from convention whereby satellites are always customised, Third Planet Orbital standardises to provide off-the-shelf Ready-To-Go solutions. Commercially supplying standardised satellite buses that are understood, tested and verified, to reduce lead times and user mission risk. Additionally, providing users access to hardware (FlatSat Rental) and knowledge (Space Engineering Services) throughout their design process enables lower overall build costs combined with increased operational confidence.

Routes to Space

Third Planet Orbital has been established in the United Kingdom to address needs apparent in the global Space industry. With a culture of being reliable, trustworthy, and consistent, Third Planet Orbital provides standardised satellite buses. Assisting space technology users with specifying satellite buses robustly, and optimising payload/mission designs with Hardware-In-the-Loop testing.
