    The European Space Agency (ESA) is today autonomously flying three interplanetary missions: Rosetta traveling to the comet Churyumov-Gerasimenko and the two orbiters Mars Express and Venus Express. The capability of supporting these and future deep-space missions is the consequence of a farsighted decision taken in 1996 to expand the ESA network of 15-m tracking antennas into the deep-space domain...

    This paper discusses a new implementation of a Gaussian minimum-shift keying (GMSK) modulator and demodulator on the European Space Agency (ESA)'s common deep-space receiver-the Intermediate Frequency Modem System (IFMS), which is a software radio based platform. The GMSK demodulator is needed for ESA's deep-space and near-Earth missions, starting with the Herschel-Planck satellites in 2008. The i... View full abstract»

    The development of error-correcting codes has been closely coupled with deep-space exploration since the early days of both. Since the discovery of turbo codes in 1993, the research community has invested a great deal of work on modern iteratively decoded codes, and naturally NASA's Jet Propulsion Laboratory (JPL) has been very much involved. This paper describes the research, design, implementati... View full abstract»

    Future space missions will put severe constraints on communication links in terms of data rates, bandwidth occupancy, complexity, and performance. The requirements imposed by the new missions and their consequences on channel code design are presented in the first part of the paper. All relevant issues, including code rates, frame lengths, modulation formats, performance metrics, complexity, and o... View full abstract»

  • Ka-Band Telemetry Operations Concept: A Statistical Approach

    Future NASA missions such as the Lunar Reconnaissance Orbiter, Kepler, James Webb Space Telescope, and Space Interferometry Mission will use Ka-band frequencies (26.5- and 32-GHz bands) for their primary science downlink instead of X-band frequencies (8.42-GHz band) due to scarcity of spectrum at X-band. At Ka-band frequencies, adverse weather events degrade the telemetry link performance to a gre... View full abstract»

    Two tropospheric calibration systems have been developed at the Jet Propulsion Laboratory (JPL) using different technologies to achieve different levels of accuracy, timeliness, and range of coverage for support of interplanetary NASA flight operations. The first part of this paper describes an automated GPS-based system that calibrates the zenith tropospheric delays. These calibrations cover all ... View full abstract»

  • Angular Position Determination of Spacecraft by Radio Interferometry

    This paper describes a variety of interferometric techniques that may be used for measuring the angular location of a spacecraft with respect to natural celestial radio sources or another spacecraft. The differential propagation time-delay techniques largely cancel the common error sources and normally achieve low angular coordinate errors. Currently, the accuracy of the techniques are in the 1-2 ... View full abstract»

  • Range Measurement as Practiced in the Deep Space Network

    Publication Year: 2007 , Page(s): 2202 - 2214
    Cited by:  Papers (4)
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (708 KB) |  | HTML iconHTML  

    Range measurements are used to improve the trajectory models of spacecraft tracked by the deep space network. The unique challenge of deep-space ranging is that the two-way delay is long, typically many minutes, and the signal-to-noise ratio is small. Accurate measurements are made under these circumstances by means of long correlations that incorporate Doppler rate-aiding. This processing is done... View full abstract»

    This paper investigates the performance of a satellite communication system which the onboard receiver regenerates the uplink pseudonoise (PN) ranging sequence. Using phase modulation, the PN ranging signal is transmitted together with the telecommand signal in the uplink and the telemetry signal in the downlink. Various ranging sequences are taken into consideration and tested prior to final inte... View full abstract»

    On January 14, 2005, the Huygens probe, which forms part of the joint NASA/ESA/ASI deep-space mission Cassini-Huygens, accomplished its spectacular descent through the atmosphere of Titan, Saturn's largest moon. This mission success, however, became possible only after the rescue of the endeavor from an implementation flaw that was discovered in 2000 during an in-orbit test of the Huygens relay-li...
