DESCRIPTION:Speakers: Andrey Arkhangelskiy (National Research Nuclear Univ
 ersity MEPhI (Moscow Engineering Physics Institute))\, Andrey Mayorov (Nat
 ional Research Nuclear University MEPhI)\nThe "Nadya" compact precision sp
 ectrometer\, currently under development at MEPhI (National Research Nucle
 ar University)\, is designed to detect and identify directional charged-pa
 rticle fluxes in the energy range from several tens to several hundred MeV
 . This energy range is of interest for the search for and detailed study o
 f heliogeophysical phenomena\, Earth's magnetospheric physics\, radiation 
 belt dynamics\, and the spatiotemporal variations of the low-energy compon
 ent of galactic cosmic rays (GCRs) in high-latitude regions. The experimen
 t's scientific program focuses particularly on the continuous monitoring o
 f solar cosmic rays (SCRs) and the investigation of the mechanisms governi
 ng their generation\, acceleration\, and propagation in the interplanetary
  medium during periods of heightened solar activity. The data obtained wil
 l be vital for real-time space weather monitoring\, modeling the radiation
  environment in near-Earth space\, and assessing radiation loads on spacec
 raft onboard electronics\; these data will complement findings from previo
 us experiments—including precision missions like PAMELA\, for which this
  specific energy range was inaccessible. The "Nadya" instrument is schedul
 ed for launch aboard the A-100 unified spacecraft platform (developed by t
 he company L5) into a circular sun-synchronous orbit with a mean altitude 
 of 450–650 km and an inclination of approximately 98°. This orbital con
 figuration ensures regular passes over polar regions characterized by low 
 geomagnetic cutoff thresholds\, as well as through the South Atlantic Anom
 aly—conditions essential for a comprehensive analysis of particle flux a
 nisotropy across various helio-geophysical environments. The spacecraft la
 unch is planned for the first half of 2027. The key performance characteri
 stics of the scientific instrumentation have been optimized to meet the st
 rict resource constraints of small satellite platforms: the total instrume
 nt mass is approximately 3 kg\, and the average power consumption during s
 tandard measurement operations does not exceed 15 W. The projected volume 
 of scientific telemetry data transmitted to the ground control segment rea
 ches 10 GB per day\, ensuring high statistical significance for the record
 ed events.\n\nhttps://indico.particle.mephi.ru/event/626/contributions/650
