“…Here, ¼ 90 þ 0 , I ¼ 90 À 0 and, 0 and 0 are, respectively, the right ascension and declination of the solar rotational axis in the equatorial reference frame J2000 [27]. The obliquity of the ecliptic ¼ 23 26 0 21 00 :4119 [28] is used to pass from the equatorial to the J2000 ecliptic reference frame.…”

With a launch planned in March 2013, the ESA Gaia mission will scan the whole sky several times during its operational five years. It will provide highly accurate astrometric observations of celestial bodies (at the sub-milli-arcsecond level) not exclusively beyond the Solar System, since about 250 000 asteroids will be observed. Gaia will thus give us the opportunity of performing various valuable tests of fundamental physics by assessing global parameters from the dynamics of minor planets; in this paper, we evaluated its performance from realistic simulated data and a variance analysis carried out from the observation residuals on a data model linearized with respect to the initial position and velocity of each asteroid and the set of global parameters. Currently, the most relevant fits turn out to be for the PPN parameter ( $ 1:4 Â 10 À3 ), the temporal variation of the gravitational constant _ G=G ( _ G=G $ 3:2 Â 10 À12 yr À1 ), the Nordtvedt parameter ( $ 2:4 Â 10 À3 ) and the Gm of Jupiter ( Gm j $ 2:9 Â 10 À15 au 3 d À2 ), which show a low level of correlation. The underestimated astrometric precision used in the simulations and the possibility to combine Gaia data with future accurate ground-based observations foreshadow more accurate determinations.

“…Using the mass of Tethys in combination with the theory of the Tethys-Mimas resonance, they derived the mass of Mimas. The density on the second line is computed from the mass determined or recommended by Campbell and Anderson (1989) and the mean radius from Davies et al (1996). No mission has yet yielded the masses of Mimas, Enceladus, Dione, Hyperion and Phoebe.…”

Cassini radio science investigations will be conducted both during the cruise (gravitational wave and conjunction experiments) and the Saturnian tour of the mission (atmospheric and ionospheric occultations, ring occultations, determinations of masses and gravity fields). New technologies in the construction of the instrument, which consists of a portion on-board the spacecraft and another portion on the ground, including the use of the Ka-band signal in addition to that of the S-and X-bands, open opportunities for important discoveries in each of the above scientific areas, due to increased accuracy, resolution, sensitivity, and dynamic range.

“…A rigorous ray path from transmit location back to satellite at receive time is reconstructed in the inertial Mars J2000 IAU coordinate system [Davies et al, 1996]. This is the coordinate system in which the spacecraft ephemeris is computed and to which the spacecraft body fixed coordinate frame is related by telemetered quaternions.…”

The use of laser altimetry in the orbit and attitude determination of Mars Global Surveyor

Abstract. Altimetry from the Mars Observer Laser Altimeter (MOLA), an instrument on board the Mars Global Surveyor (MGS) spacecraft, has been analyzed for the period of the MGS Science Phasing Orbit-1 (SPO-1) mission phase. Altimeter ranges have been used to improve significantly the orbit and attitude knowledge of the spacecraft by the use of crossover constraint equations derived from short passes of the MOLA data. These constraint equations differ from traditional crossover constraints and exploit the small footprint associated with laser altimetry. The rationale for using this technique with laser altimetry over sloping terrain is laid out and evidence of the resulting benefit is presented.
