    I get it up to the bit where it mentions angular discrimination. Then I have no idea what this means, and am thereafter rather lost.

    Will be gone for fifteen minutes. Which almost gives you enough time to read it. Sorry. Thanks.

    I think angular discrimination refers to the angular error in which the receiver can be positioned in relation to the direction of the wave.

    For example, if you have a satellite dish which receives a wavelength of 10 cm, and the dish is 10cm long, then you have a zero margin for error (and thus the angular discrimination is zero). The larger the dish, the greater the inaccuracy for the receiver can be. If the wavelength is 10 cm and the dish is 1km long, the margin of error is larger.

    See the picture:


    The top diagram has a small satellite (oval), and the angular discriminant is smaller than the second diagram, which has a larger satellite.

    Essentially, angular discrimination is the maximum error an signal can be from a position directly above the centre of the satellite.

    I see I'm just going in circles in here...
