Hosted Payloads
The Iridium NEXT spacecraft design allows for up to a 50-kilogram
hosted payload. Hosted payloads enjoy the interconnectivity of the
66 satellite Iridium network and near-real time relay of data to and
from space, providing the end user global coverage at a fraction
of the price of a dedicated mission. The end user receives hosted
payload data via an IP interface to Iridium facilities, which obviates
the need for any customer owned ground stations. Additional
benefits to hosted payload missions include persistence, revisit
capabilities and resilience.
