English

Subject field(s)
  • Computer Programs and Programming
  • Launching and Space Maneuvering
  • Satellite Telecommunications
DEF

The software responsible for maintaining the attitude of the spacecraft.

CONT

The attitude control software is state-of-the-art and includes algorithms for despin, Sun and Earth orientation and capture, state-sampled network control, reaction wheel desaturation, attitude recovery and intraspacecraft communication.

OBS

In addition, it also performs several deployment operations as the spacecraft moves into its nominal attitude.

DEF

Logiciel responsable du maintien de l'attitude de l'engin spatial.

CONT

Samedi 9 octobre, le logiciel de protection aux erreurs a placé la sonde en configuration d'attente sécurisée suite à un défaut fugitif entre le logiciel de contrôle d'attitude et les commandes. Ces éléments assuraient le contrôle de la sonde à ce moment-là.

English

Subject field(s)
  • Space Exploration Equipment and Tools
CONT

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].

OBS

three axis magnetometer; CAM: term and abbreviation officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • three-axis magnetometer

French

Domaine(s)
  • Équipement et outillage d'exploration spatiale
CONT

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).
