I am happy to answer questions of a technical and regulatory nature in the area of satellite and radio communications. I am best able to answer questions about systems and technology and less able to respond to questions about specific hardware and equipment setup and installation, but I'm happy to try and address any question put my way. My main areas of expertise are link analysis (link budgets, performance, Eb/No, capacity), interference analysis (C/I, protection ratios, interference avoidance), spectrum management (frequency coordination, inter-system sharing), Radio Regulation (ITU, ITU-R) and satellite technologies and trends.
I have worked as a satellite communications engineer at a professional level since 1983. Since 1990, as Managing Director of RPC Telecommunications Limited, I have operated a private satellite communications consultancy and have provided technical support to many satellite operators and national governments.

I've been interested in radio communcations since I built my first single-diode receiver back in 1970 and fascinated by space since the Apollo program of the 1960s (watching Neil Armstrong's first steps on the Moon back in 1969). Since I was never going to be an astronaut I managed to get a job in satellite communications as the next best thing!
There's always something to learn! Staying ahead of the latest technologies and trends is a constant learning process.

Hello, Many thanks for this question. Regarding satellite internet in India, I don't personally get involved with internet provisioning, so I don't have any direct information, but the Satellite
Hello, Many thanks for this question. Unfortunately it's much too complicated to describe the process here. You need an accurate model of the sun's movement relative to the Earth and then you need
Hi again Anurag, There is not really a fixed relationship between the roll-off and the spacing factor in the way that you are looking for. It depends on the spectrum shape of the your carrier and the
Hi Anurag, Yes, what you have stated is exactly the case. BUT there is an important clarification here. It is true based *only* on the assumption that the roll-off factor is 0.35 and that the "carrier
Hi Anurag, Really the issue depends on what ISRO mean when they allocate you 6 MHz. Do they allow a guard-band between your allocation (in which you can completely fill the 6 MHz with your carrier
