... 8, ``Celestial Mechanics'', 2002 First results of GPS orbit determination with GRAPE package using a square--root information filter M. O. Keshin Institute of Applied Astronomy, St. Petersburg, Russia The zero--differenced carrier phase measurements contain the distance be­ tween the phase centres of receiver and transmitter antennas biased by unknown integer number of cycles (phase ambiguities). ... In the case of GPS the problem of solar radiation pressure modelling is of primary importance. ...

Ground Support of RadioAstron . Control and Tracking Stations . RadioAstron satellite control (command transmission, telemetry, orbit measurements) will be conducted from Evpatoria and Bear Lake control stations. ... Coarse orbit measurements will be carried out from control stations. Each measurement takes ten minutes. ... Orbit measurements at tracking stations give only radial component of spacecraft velocity but the measurements are going continuously during observing sessions. ...

... Light weight and low power consumption combined with nearly quantum limited sensitivity and a wide tuning range of the superconducting local oscillator make SIR a perfect candidate for many practical applications. Superconducting Integrated Receiver (SIR) [1] comprises on one chip a low-noise SIS mixer with quasioptical antenna, an Flux-Flow Oscillator (FFO) acting as a Local Oscillator (LO) and a second SIS harmonic mixer (HM) for the FFO phase locking. ...
