Spot the ISS in this video of the feed tracking NSS7 inclined satellite. Simple, low-cost and retrofit-able.
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
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 developed a range of special frequency feeds for offset and center fed reflectors. Some examples 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) Machined parts can use a tool to go around corners bringing benefits in side-lobe performance compared to a moulded horn.
iSat integrate 1:1
This assembly is an
4 port linear feed
with a tx-switch
This is an example
of a linear Ka-band
transmit with filters
and side entry for TWTA.
It features a precision
mechanism for easy
polarisation isolation optimisation during installation.
