Three Axis Magnetometer [-] TAM... Redundant TAMs are provided to sense the local strength and direction of the Earth's magnetic field. Each TAM consists of a sensor and a separately packaged electronics unit. The analog outputs provided by the TAM allow for sensing magnetic field data in three orthogonal axes. TAM-Operation Once the TAM is powered there will be no ground interactions necessary. The TAM data is used by the FSW ACS [Flight Software Attitude Control Subsystem routine to determine the local magnetic field when reaction wheel momentum unloading is deemed necessary via the magnetic torque rods [Landsat].

On peut mesurer ainsi l'intensité d'un champ magnétique axial. Certains magnétomètres plus sophistiqués peuvent mesurer un champ global selon ses 3 axes x, y et z. On parle alors de magnétomètre triaxial.

OBS

magnétomètre triaxial : terme uniformisé par le Groupe de travail de la terminologie de Radarsat-2 (GTTR0).

Mais une première série de modifications interviendra dès 1997. Tout d'abord, la fusée n'aura plus d'éléments provenant des autres pays de la CEI et sera donc de construction purement nationale. Ensuite, le système de pilotage analogique sera remplacé par un nouveau calculateur de bord qui permettra d'éliminer le pointage azimutal, de diminuer le poids de 200 kg et de réduire de 40 % l'aire de retombées des étages.
