mfb- RAAN is not normally considered in a frozen orbit as it must always precess relative to something (e.g. a sun-sync orbit processes relative to an inertial system). Perigee is important in constellations with small altitude separations between orbit planes, such that the apogee of one is...

Hello, I'm interested in how to formulate a simple constellation in which there are two satellites with identical orbital parameters (eccentricity <0.003, same inclination and aligned arg. Perigee, same RAAN) but which have different altitudes (e.g. Semi major axis) which are around 1000km and...

This is nonsense. Go to Wikipedia and look up 'Rayleigh scattering'

Mathematics. A robust topic that is a foundation for many career paths. You know it makes sense.

So exascale is going to be predominantly a power issue. What about the zeta scale platform? What kind of new and unique issues are we going to come across At that point?

Thanks for that. Looks very comprehensive.

Hello chaps, I'm trying to calculate absorption coefficients of gases at moderate temperatures ie ranges in which diatomic gases (such as N2 orO2) are partially disassociated or ionised, therefore including molecular bands as well as continuum. Can anyone recommend some suitable reading...

You need to transform your equations from 2d Cartesian to 2d cylindrical, taking care on all the differential operators (not sure what equations you're using). You can then discretise these using conventional finite element techniques (e.g galerkin or similar). Note: Cartesian xy will yield...

Gentlemen, I've stumbled upon a book called 'Machian Relativity: The New Theory That No Scientist Can Disprove' by Glyn Phillips, and was just wondering whether anybody else has come across it and/or understands what this chap is going on about. I had a quick flick through some pages on amazon...

A number of possible career options are available to you, ranging from a service expert at MacDonalds to chief scientist at one of the UK research companies. And everything in between. What do you want to do? Earn money? Defend the country? Write papers and bathe in academic glory? Just make...

Euler (most prolific by far), Gauss and Hilbert

Um.. I think you need to be a bit more specific. What form are you working with?

I suspect MFN is right and the assumptions in drag coefficient and it's impact on the final position is probably dominant over issues of initial angular momentum

Hmm, I would guess the equivalent of about 3000 times the mass of Jupiter in negative energy should just about do the trick.

That is somewhat over the top for a compiler. Also, any code worth it's salt and written to actually do something useful would not have many cases where array bound errors could be spotted at compile time
