TeamCast is introducing a solution for optimizing satellite links. The solution uses a feedback channel through a regular low bitrate internet connection to optimize the link budget, and increase the available payload capacity while keeping the costs low. The feedback information elaborated by the downlink Neptune receiver is used by the uplink Vyper modulator to pre-correct the linear and non-linear impairments of the on-board transponder chain.
The optimization is automatic and transparent for the user. It can be used while the link actually carries user data, without any need to put the transmission on hold. No specific knowledge of the transponder characteristic is necessary; no specific skills are required for the operator.
The link budget automatically increases while the link is used. That means the link margin is getting better providing the possibility either to secure the link against unexpected adverse conditions or increase the useful bandwidth by adjusting the modulation parameters.
“Our fully automatic solution offers increased transmission performance to operators, without requiring specific equipment or knowledge” says Christophe Trolet, head of the Satellite Business Unit at TeamCast. “We are proud to offer this new and powerful tool to operators, without adding operational complexity. Everything is included in the Vyper modulator and the Neptune receiver, both meeting DVB-S2/S2X requirements for the highest operational flexibility and the payload capacity for a given transponder”.
