iSat is specialised in Ka-band VSAT terminal design. It designs RF feeds and assemblies and develops, installs, trains and supports their implementation worldwide. Established in 2011 and based in Farnborough, the company has extensive VSAT testing and integration facilities.
iSat was able to obtain the contract thanks in part to the support provided by the European Space Agency (ESA) through the Entry element of the ARTES programme. “ESA Entry support was instrumental in helping us deliver solutions based on the new extended Ku- and Ka-band frequencies,” says David Harper, CEO of iSat. “In particular, ESA is helping us in the development of innovative Ka-band feeds with optimized pointing accuracy which gives improved signal quality and faster commissioning times. This contract award required a turnkey solution where the waveguide feeds and orthomode transducers funded in part by ESA is a key differentiator”.
“The iSat contract is a good example of how ARTES Entry helps small but enterprising newcomers get a foothold in the very competitive global space industry,” says Fabrizio De Paolis, Ground Segment Engineer at ESA.
ARTES Entry is designed specifically to support European and Canadian SME Newcomers, which have not worked with ESA within the past ten years. In recognition of the importance of helping newcomers, in December 2015 the ESA Member States raised the co-funding level for ARTES Entry from 50% to 75%.

In January this year iSat Networks (iSat) was awarded a contract by ESA to develop a feed adjustment mechanism, with both manual and motorised operation, to provide improved alignment of Ka-band VSAT antennas and tracking of inclined-orbit satellites up to ~±3° in the C, X- and Ku-bands. The inclined system reduces the costs of using inclined capacity.

The Ka-band adjustable feed development will provide enhanced RF performance for Ka-band antenna systems and facilitate easier installation by less skilled installers. The unit is available with or without a rear mount BUC bracket which reduces waveguide loss.
Preliminary Results for inclined tracking
The C, X- and Ku-band motorised feed development will provide a simple retrofit solution to enable the tracking of inclined orbit satellites at a substantially lower cost than currently available Az-El tracking systems.
iSat has carried out initial tests of the motorised feed using a 1.8 m offset antenna at Ku-band (11.45 GHz) tracking the beacon on NSS-7 which is operating in a 1° inclined orbit. The tests were conducted at our facility in Cody Technology Park, Farnborough.
The antenna gain pattern is shown below – note a >20dB loss for a 1° mis-point.
The next plot shows the beacon level at the receiver with no feed tracking – in fact the beacon signal is completely lost due to carrier being in the noise, as the satellite oscillates in its inclined orbit
The final plot below shows the beacon level at the receiver when the iSat feed tracking is enabled. The plot shows the feed position alongside the beacon level which remains steady (<1dB variation) and shows no loss of signal associated with the tracking.
The work continues at iSat, and anyone interested can contact us now for more information.
25 February 2016: After a year’s discussion with ESA, and with a support letter from UK Innovate, following a negotiation meeting held at ESA’s office in Harwell on 1st February 2016, iSat LTD (Integrated Satellite Applications Technologies Limited) can officially announce the award of a contract entitled "Robotic Feed Development".
The program will be carried out under a program of, and co-funded by, the European Space Agency.
The project is to develop a feed tracking mechanism for VSAT antennas:-
- New and retrofit Ku and X-band inclined satellites tracked with ephemeris data, which has lower down-time, lower cost and more precision than current AzEl systems.
- Mechanically adjusted Ka-band feed holder, for accurately aligning the VSAT installation saving 1-2 dB’s and installation time.
- Motorised Ka-band feed holder, for professional high accuracy tracking on VSATs using less power and retaining the wind loading of the original antenna manufacturers equipment.
We're able to develop mechanical prototypes for evaluation now and our first motorised products are expected in a few months.
iSat develops innovative VSAT solutions including “Kurtz-above” solutions; integrating Feed design solutions with the latest reflector technology.
