GRBAlpha: the smallest astrophysical space observatory -- Part 1: Detector design, system description and satellite operations
András Pál, Masanori Ohno, László Mészáros +42
Aims. Since launched on 2021 March 22, the 1U-sized CubeSat GRBAlpha operates and collects scientific data on high-energy transients, making it the smallest astrophysical space obs…
Early results from GRBAlpha and VZLUSAT-2
Jakub Ripa, Andras Pal, Masanori Ohno +37
We present the detector performance and early science results from GRBAlpha, a 1U CubeSat mission, which is a technological pathfinder to a future constellation of nanosatellites m…
Simulations of expected signal and background of gamma-ray sources by large field-of-view detectors aboard CubeSats
Gábor Galgóczi, Jakub Řípa, Riccardo Campana +19
In recent years the number of CubeSats (U-class spacecrafts) launched into space has increased exponentially marking the dawn of the nanosatellite technology. In general these sate…
GRBAlpha: A 1U CubeSat mission for validating timing-based gamma-ray burst localization
András Pál, Masanori Ohno, László Mészáros +26
GRBAlpha is a 1U CubeSat mission with an expected launch date in the first half of 2021. It carries a 75 x 75 x 5 mm CsI(Tl) scintillator, read out by a dual-channel multi-pixel ph…
The CHEOPS mission
Willy Benz, Christopher Broeg, Andrea Fortier +107
The CHaracterising ExOPlanet Satellite (CHEOPS) was selected in 2012, as the first small mission in the ESA Science Programme and successfully launched in December 2019. CHEOPS is…
CAMELOT: design and performance verification of the detector concept and localization capability
Masanori Ohno, Norbert Werner, András Pál +16
A fleet of nanosatellites using precise timing synchronization provided by the Global Positioning System is a new concept for monitoring the gamma-ray sky that can achieve both all…
