ALAT stands for Attitude-LATtitude, therefore a lattitudinal-statement (Lattitude) of the flight-attitude of the satellite. The reference-level of the flight-attitude-determination is the orbitplane of the satellite. The latitudinal-statement ALAT of the flight-attitude indicates how far the +Z-axis of the satellite shows out of this plane. Positive values show an inclination northwards, negative an inclination of the axis southwards. The main-lobe- direction of the antennas is in +Z-direction. The nearer ALAT therefore approaches to 0, the better are the antennas oriented in the north/south- direction to Earth?s center.
