Overview

The Mars Global Surveyor Magnetometer/Electron reflectometer investigation was implemented without the usual "magnetometer boom" often used to separate the sensitive magnetic sensor and spacecraft. This separation is important, as it allows for attenuation (as 1/r**3) of spacecraft-generated magnetic fields and helps achieve the most accurate measurement of the ambient magnetic field. To save valuable spacecraft resources (e.g., mass), the fluxgate magnetometer sensors were mounted at the very ends of the two solar panels (see illustration). These solar panels were specially engineered ( Acuña, M. H., et al, JGR, 106, E10, 23403-23417, doi: 10.1029/2000JE001404, 2001) to minimize any stray magnetic fields. To fully calibrate the magnetic field observations, we conducted in-flight calibration maneuvers to characterize the magnetic field produced by the spacecraft. We then used these data to develop a model of the spacecraft magnetic field so that this contribution could be removed from the data.

The figures below show some examples and illustrate how well the spacecraft field is modeled. This work was completed within six months of the February 2000 receipt of calibration data, and fully calibrated magnetometer data began to flow into the PDS in August 2000 (please see schedule).

Fully calibrated MGS MAG/ER data are available at the PDS [external link].

Some high time resolution (detail word) data are available from the PDS [external link].

The following diagram shows the different configurations of the solar arrays and High Gain Antenna (HGA) during the different phases of the mission. Please note that the location of the HGA was fixed during cruise and aerobraking. However, the HGA is mobile during the mapping phase of the mission.

The plots provided are intended to give you some insight into the High Gain Antenna (HGA) magnetic mapping and the model used to approximate the field of the HGA in our data reduction. In this test, the solar panels (upon which the magnetic sensors sit) are positioned and held fixed, while the High Gain Antenna is articulated about one axis. This was done while the spacecraft was in the shadow of Mars to avoid confusion with effects related to the power subsystem. The difference field (mag #1 - mag #2) reveals a magnetic signature due to the HGA movement which we used to estimate the position and magnetic moment of the assembly. The light blue line shows the modeled difference field; you can judge how well the spacecraft model works by how well the difference field is approximated by the light blue line.

The following plot shows a HGA articulation, the white line is the DIFFERENCE between the vector fields measured by the two sensors in spacecraft payload coordinates. Subtracting one from the other removes (the much larger) variations in the ambient field and allows us to isolate movements of the HGA. The blue line shows the corresponding DIFFERENCE in the model field at each sensor location for comparison.

NOTE that the model included a constant adjustment for each test that is not reflected in the plots. What you are interested in is not the constant offset of the data and the model, but how well the VARIATION in the model difference compares with the VARIATION in the data difference.

Why do we allow for a constant offset from one test (HGA articulation) to the next? The tests must all be done when the spacecraft is in darkness (shadowed by the planet) in order to avoid confusion with the dynamic field associated with currents in the power subsystem. The time it takes to complete an articulation of the HGA is a large fraction of the eclipse period so we can only get one articulation per orbit. In the time between test, the static spacecraft field may have changed a bit, so we allow for this by allowing a constant (throughout any one HGA articulation) offset from eclipse to eclipse.

The HGA model was derived from these data (differences in vector field at each sensor) using a generalized inverse matrix method (Connerney, 1981). We found that a simple offset dipole model (where offset is with reference to the HGA coordinate system) did as good a job in modeling the field of the HGA as did a quadrupole or octupole expansion (about the same origin) so this is the model we adopt for data reduction.

The following plot shows the variation in the model HGA field at each sensor location for one of the HGA articulation tests conducted in early 2000.
