Verification of the Timing System for the X-ray Imaging and Spectroscopy Mission in the GPS Unsynchronized Mode
Megumi Shidatsu, Yukikatsu Terada, Takashi Kominato +59
We report the results from the ground and on-orbit verifications of the XRISM timing system when the satellite clock is not synchronized to the GPS time. In this case, the time is…
Development of the Timing System for the X-Ray Imaging and Spectroscopy Mission
Yukikatsu Terada, Megumi Shidatsu, Makoto Sawada +62
This paper describes the development, design, ground verification, and in-orbit verification, performance measurement, and calibration of the timing system for the X-Ray Imaging an…
Soft X-ray Imager aboard Hitomi (ASTRO-H)
Takaaki Tanaka, Hiroyuki Uchida, Hiroshi Nakajima +25
The Soft X-ray Imager (SXI) is an imaging spectrometer using charge-coupled devices (CCDs) aboard the Hitomi X-ray observatory. The SXI sensor has four CCDs with an imaging area si…
Time Assignment System and Its Performance aboard the Hitomi Satellite
Yukikatsu Terada, Sunao Yamaguchi, Shigenobu Sugimoto +24
Fast timing capability in X-ray observation of astrophysical objects is one of the key properties for the ASTRO-H (Hitomi) mission. Absolute timing accuracies of 350 micro second o…
In-orbit performance of the soft X-ray imaging system aboard Hitomi (ASTRO-H)
H. Nakajima, Y. Maeda, H. Uchida +46
We describe the in-orbit performance of the soft X-ray imaging system consisting of the Soft X-ray Telescope and the Soft X-ray Imager aboard Hitomi. Verification and calibration o…
The ASTRO-H X-ray Astronomy Satellite
Tadayuki Takahashi, Kazuhisa Mitsuda, Richard Kelley +250
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planne…
