In-orbit Demonstration of X-ray Pulsar Navigation with NinjaSat
Naoyuki Ota, Takuya Takahashi, Toru Tamagawa +26
This study demonstrated the pulsar navigation capability of the CubeSat X-ray observatory NinjaSat, which is equipped with two Gas Multiplier Counters (GMCs). The GMCs are sensitiv…
NinjaSat: Astronomical X-ray CubeSat Observatory
Toru Tamagawa, Teruaki Enoto, Takao Kitaguchi +22
NinjaSat is an X-ray CubeSat designed for agile, long-term continuous observations of bright X-ray sources, with the size of 6U ( mm) and a mass of 8 kg.…
Gas selection for Xe-based LCP-GEM detectors onboard the CubeSat X-ray observatory NinjaSat
T. Takeda, T. Tamagawa, T. Enoto +18
We present a gas selection for Xe-based gas electron multiplier (GEM) detectors, Gas Multiplier Counters (GMCs) onboard the CubeSat X-ray observatory NinjaSat. To achieve an energy…
Multiplexing lobster-eye optics: a concept for wide-field X-ray monitoring
Toru Tamagawa, Keisuke Uchiyama, Ryota Otsubo +13
We propose a concept of multiplexing lobster-eye (MuLE) optics to achieve significant reductions in the number of focal plane imagers in lobster-eye (LE) wide-field X-ray monitors.…
