Reading STEREO ephemerides as SPICE kernels
نویسنده
چکیده
SPICE data files are known as “kernels”, and come in a wide variety. Mission specific kernels provide information about the orbital position and orientation of the spacecraft as a function of time. On top of these are more generic kernels, such as a general solar system ephemeris, planetary constants, and so on. The SPICE system puts these various elements together into a common integrated system.

Exploring Trade-Offs between Specialized Dataflow Kernels and a Reusable Overlay in a Stereo Matching Case Study
FPGAs are known to permit huge gains in performance and efficiency for suitable applications but still require reduced design efforts and shorter development cycles for wider adoption. In this work, we compare the resulting performance of two design concepts that in different ways promise such increased productivity. As common starting point, we employ a kernel-centric design approach, where co...

Introduction The Mars Orbiter Camera (MOC) has been operating on board of the Mars Global Surveyor (MGS) spacecraft since 1998. It consists of three cameras Red and Blue Wide Angle cameras (FOV=140 deg.) and Narrow Angle camera (FOV=0.44 deg.). The Wide Angle camera allows surface resolution down to 230 m/pixel and the Narrow Angle camera down to 1.5 m/pixel. This work is a continuation of the ...

متن کاملReal-time Time and Frequency Transfer Using Gps Carrier Phase Observations
A client-server based data communication scheme was developed in order to establish a permanent and dynamic real-time GPS network for relative time and frequency transfer. The Kalman-filter-based real-time processor uses station pairwise common-view phase observations for estimating the receiver clock and tropospheric parameters. Orbit determination is based on real-time broadcast ephemerides a...
متن کاملAn approximation to the errors in the planetary ephemerides of the Astronomical Almanac
Errors in the planetary coordinates of the Astronomical Almanac are approximated by comparing their fundamental ephemerides, upon which they are based, with a more recent ephemeris. JPL’s DE200 provided the fundamental planetary and lunar ephemerides of the Astronomical Almanac for the years, 1984–2002, and DE405 has replaced DE200 in that role, starting in 2003. Recently, new observational mea...
