Fuel consumption for Attitude Control Not according to G* Website globalstar.com "Stabilization: The satellite operates in a body-stabilized, three-axis attitude control mode. It is unique in that it is among the first of its kind to utilize the Global Positioning System to keep track of its orbital location and attitude. It also uses sun sensors, Earth sensors, and a magnetic sensor to help maintain its attitude. The satellite contains a number of momentum wheels and magnetic torquers to minimize propellant consumption for attitude control, and utilizes five thrusters for orbit-raising, station-keeping maneuvers and attitude control. The spacecraft's monopropellant hydrazine thrusters are fueled from a single on-board propellant tank, sufficient to keep the satellite in its proper orbit for the full lifetime. " Note the "momentum wheels". That's the effect where you: 1. Stand on a swivel chair. 2. Hold a spinning bicycle wheel out in front of you (you should be looking at the side of the wheel) 3. Raise the wheel over your head, so it is now spinning horizontally 4. You will notice that you start to twist on the swivel chair as you do No 3. Alternatively try to make yourself twist on the swivel chair without the bicycle wheel. Pretty difficult isn't it. Bit like being a satellite trying to keep those G* users in focus without "momentum wheels" or using propellant.
