Regenerative Pseudo-Noise Ranging for Deep-Space Applications
نویسندگان
چکیده
A method for regenerating a pseudo-noise (PN) ranging signal at a spacecraft is presented. This method allows for an increase of up to 30 dB in received downlink ranging power. The increased power can be used to decrease the measurement uncertainty, reduce the time of the measurement, or increase the power allocated to the downlink telemetry. This system is being implemented in the Spacecraft Transponding Modem that is being developed by JPL for NASA.

PN Code Ranging System for Accurate and Long Distance Range Measurement
A ranging-sequence system is a system in which a periodic binary (±1) ranging sequence modulates an uplink carrier to produce a signal that is transmitted from an Earth station to a transponder in the spacecraft whose range from the Earth station is to be measured. This modulated uplink carrier is received and processed by the spacecraft transponder, either in a simple turnaround (non-regenerat...
متن کاملDevelopment of the Advanced Deep Space Transponder
We present the architecture and design of a new transponder to support deepspace and near-Earth missions in the post-2010 time frame. This transponder is designed to provide direct-to-Earth command and telemetry service; spacecraftto-spacecraft command and telemetry service; direct-to-Earth navigation in the form of coherent Doppler turnaround, sequential turn-around ranging, pseudo-noise regen...
متن کاملComparison of Two Quantitative Susceptibility Mapping Measurement Methods Used For Anatomical Localization of the Iron-Incorporated Deep Brain Nuclei
Introduction Quantitative susceptibility mapping (QSM) is a new contrast mechanism in magnetic resonance imaging (MRI). The images produced by the QSM enable researchers and clinicians to easily localize specific structures of the brain, such as deep brain nuclei. These nuclei are targets in many clinical applications and therefore their easy localization is a must. In this study, we aimed to i...

Deep-space optical communications is an active area of research at JPL. Optical communications is being pursued as an alternative to RF communications, because of the relatively low mass, volume, and power requirements and the potential for increased data rates. The emphasis of current deep-space optical communications research at JPL is in gaining ground-based receiver experience, as a precurs...
متن کاملLearning with Pseudo-Ensembles
We formalize the notion of a pseudo-ensemble, a (possibly infinite) collection of child models spawned from a parent model by perturbing it according to some noise process. E.g., dropout [9] in a deep neural network trains a pseudo-ensemble of child subnetworks generated by randomly masking nodes in the parent network. We examine the relationship of pseudo-ensembles, which involve perturbation ...
