In a nutshell SatNOGS is focused on publicly available transmission data either from radio amateur, experimental or meteorological satellites.

Ground-stations are operated by individuals organizations, or corporations using existing antenna systems (from simple static quadrafilar antennas to large radiotelescopes) and SDRs.

All data are publicly available for all. That can be very useful for example for experimental university cubesats teams that have a hard time receiving their own satellites.

Proprietary solutions focus usually on building their own hardware infrastructure instead of crowdfunding it. The data are by default available only to the operators of the satellites, they incorporate several pricing schemes.

Needless to say that SatNOGS caters very different needs than such proprietary networks.
