iSat have delivered assemblies to many countries across the EMEA region. iSat is an Authorised Economic Operator by UK Government Customs. This means our imports and exports can be delivered in a more timely fashion, keeping projects on track. The audit for our processess and security were extensive and took 4 days, so this is a huge vote of confidence in iSat as an integrator serving the global satellite industry.
iSat is an innovative driven company, contracted with the European Space Agency to develop a single axis tracking system that can extend the life of a satellite and/or give user access to low cost satellite bandwidth. The case study illustrates the exciting development journey that results in a product ready exploitation in commercial systems.
Applicable to offset reflectors 1.2mtr to 3.8mtr and inclined satellites such as
iSat racks are a premium solution for customers looking for more than a functioning rack. iSat's skill and experience creates high performance racks. Wiring that reduces interference and cable termination double checked for continuity, length (strain), curvature (minimum curve radius), and placement (ease of access to rear rack equipment). The design of racks orders the equipment from top to bottom for signal flow, heat management and ease of use. Monitoring points and patch panels for RF levels offer complete control of RF levels. Finally, iSat handle all free issue equipment with extreme care, so when the rack is installed, it looks brand new and shiny, and reflects the pride that the customer feels for their capital spend.
Transponders with Ka-band are becoming common. What is not so common is a supplier that has relevant actual experience of supplying, pointing and installing/ commissioning Ka-band VSATs. iSat is the world's leading experience in Ka-band antenna systems at 1.2, 1.8 and 2.4mtr antenna size. At Ka-band these relfectors are already approaching illuminating an entire transponder.
iSat's high performance feeds
iSat have a grown a reputation for creating feeds that can address new ITU transponder frequencies quickly and efficiently. iSat feeds provide impressive cross pol and sidelobe results when range tested; each new feed exceeding requirements. Frequencies recently developed are:-
Transmit Receive Polarisation
18.10 – 18.40 21.40 – 21.70 Linear
24.65 – 25.25 21.40 – 22.00 Linear
14.50 – 14.80 13.40 – 13.70 Linear
27.50 – 27.60 21.40 – 21.50 Circular
Our feeds are accurately machined which has two benefits:-
a)There is no cost of a mould- which is expensive when you only need a few hundred or thousand.
b)A mould must be pulled out from the horn along one dimension and therefore can’t go around corners. A machine can use a tool to go around corners. This ability means our side-lobe performance is better than a moulded horn. When the horn focuses the beam better, the efficiency is higher.
Feeds that involve horns, OMT, and polarisers with various matching transitions have been designed.
4 port feeds have also been designed, where the OMT covers the transmit and receive band simultaneously, and after the OMT, the TX and RX bands are split by diplexer to arrive at 4 ports.
These developments have been combined with earth station components to create turnkey terminal designs, suitable for commercially exploiting new frequency spectrums.
iSat X-Band VSAT Service Coverage
iSat X-band coverage are transmitting at 7.9 to 8.4GHz and receiving at 7.25 to 7.75GHz. iSat engineered a range of terminals including C-COM at X-band, and they are available PV rating 'Unclassified' ready for export.
