GOCAT OGS - DTE
other
Multiple groups world wide are currently developing laser communication terminals for downlinking data from satellites in the LEO orbit directly to earth in the so call DTE (Direct To Earth) configuration. These terminals will require a network of ground stations to downlink their data. The challenge for the communication industry is the following: - as no CCSDS standard is defined yet and currently different space terminal architectures are being developed (wavelength, no channels, Modulation and coding formats, and protocols) meaning that interoperability will be challenging. Therefore a single station that can serve all will be of high value. - There is a ‘Chicken-Egg’ situation where customers will likely not invest in space terminals until there is an operational OGS network capable of downlinking the data from satellites and the OGS network will be not implemented until there is a strong pull from the market to do so. TNO and its partners recognize this issue and are actively working to break this deadlock.
