Each positioning constellation has about 30 satellites. Using data from all four existing constellations isn't going to use all of the channels, let alone reach three digits. About half of the satellites are visible at any one time and receivers usually don't use satellites close to the horizon -- the receivers I worked on defaulted to only use satellites over thirty degrees above the horizon (I think -- it's been a few years). This is assuming that the receiver is even capable of handling all four constellations. Pauli |
