1. Calculating the Position and Velocity Components of HST
... The HST uses an onboard model of its orbit to perform in real-time various control functions relating to spacecraft operations and observation support. ... New coefficients for the ephemeris are updated every other day, and are archived as FITS keywords for each HST observation data set. Using these coefficients,an observer can perform a variety of calibration and characterization calculations relating to the orbital position and velocity of the telescope. ...

3. IESP-2M Results Page
. An example of ULF electromagnetic fields detection by the IESP-2M instrument. The figure presented is the dynamic spectrogram. E and B components are measured in satellite coordinates. Observations were made in the auroral region. Electromagnetic turbulence, which was observed mostly in electric components, is typical for this phenomenon. Fig.1 .

The Yarkovsky Effect in the Motion of NEAs . ... In this paper we evaluate the Yarkovsky effect on the motion of NEAs under the assumption that this acceleration depends on heliocentric distance as 1/r 2 and is characterized by the transverse component 2 in the orbital coordinate system. ... In some instances the Yarkovsky effect can be estimated by using only optical observations. Accounting for the Yarkovsky effect permits to include more optical observations in the orbit fitting process. ...
