Using an Internet connection to optimise the link budget, the automatic satellite link optimisation solution is able to increase the available payload while keeping operators’ costs low, said TeamCast
TeamCast, a solutions provider of digital modulation technologies for digital terrestrial television (DTT), wireless transmission and satellite applications, has introduced a solution that is capable of optimising satellite links.
Designed to increase the available payload capacity, the new solution uses a feedback channel through a low bitrate Internet connection to optimise the link budget. The feedback information elaborated by the downlink Neptune receiver is used by the uplink Vyper modular to pre-correct the linear and non-linear impairments of the on-board transponder chain.
The satellite link optimisation solution can be used while the link carries user data, eliminating the need to put the transmission on hold, said TeamCast. The link budget automatically increases while the link is used, thus allowing operators to secure the link against unexpected adverse conditions, or to increase the bandwidth by adjusting the modulation parameters.
Stressing that the automatic solution offers increased transmission performance to operators, Christophne Trolet, head of the satellite business unit at TeamCast, added: “Everything is included in the Vyper modulator and the Neptune receiver; both meet DVB-S2/S2X requirements for the highest operational flexibility, and the payload capacity for a given transponder.”
