The Gamma-Ray Integrated Detectors (GRID) is a space mission concept dedicated to monitoring the transient gamma-ray sky in the energy range from 10 keV to 2 MeV using scintillation detectors onboard CubeSats in low Earth orbits. The primary targets of GRID are the gamma-ray bursts (GRBs) in the local universe. The scientific goal of GRID is, in synergy with ground-based gravitational wave (GW) detectors such as LIGO and VIRGO, to accumulate a sample of GRBs associated with the merger of two compact stars and study jets and related physics of those objects. It also involves observing and studying other gamma-ray transients such as long GRBs, soft gamma-ray repeaters, terrestrial gamma-ray flashes, and solar flares. With multiple CubeSats in various orbits, GRID is unaffected by the Earth occultation and serves as a full-time and all-sky monitor. Assuming a horizon of 200 Mpc for ground-based GW detectors, we expect to see a few associated GW-GRB events per year. With about 10 CubeSats in operation, GRID is capable of localizing a faint GRB like 170817A with a 90% error radius of about 10 degrees, through triangulation and flux modulation. GRID is proposed and developed by students, with considerable contribution from undergraduate students, and will remain operated as a student project in the future. The current GRID collaboration involves more than 20 institutes and keeps growing. On August 29th, the first GRID detector onboard a CubeSat was launched into a Sun-synchronous orbit and is currently under test.

GRID:在多信使天文学时代监测瞬态伽马射线天空的学生项目

伽马射线集成探测器 (GRID) 是一种空间任务概念,致力于使用低地球轨道立方体卫星上的闪烁探测器监测能量范围为 10 keV 到 2 MeV 的瞬态伽马射线天空。GRID 的主要目标是本地宇宙中的伽马射线暴 (GRB)。GRID 的科学目标是与地基引力波 (GW) 探测器(如 LIGO 和 VIRGO)协同工作,积累与两颗致密星合并相关的 GRB 样本,并研究这些物体的喷流和相关物理学。它还涉及观察和研究其他伽马射线瞬变,如长伽马射线暴、软伽马射线中继器、地面伽马射线闪光和太阳耀斑。由于在不同轨道上有多个立方体卫星,GRID 不受地球掩星的影响,可作为全天全天监测器。假设地面 GW 探测器的视野为 200 Mpc,我们预计每年会看到一些相关的 GW-GRB 事件。大约有 10 个立方体卫星在运行,GRID 能够通过三角测量和通量调制定位像 170817A 这样的微弱 GRB,误差半径约为 10 度,误差半径为 90%。GRID 由学生提出和开发,本科生的贡献相当大,未来仍将作为学生项目运行。目前的 GRID 合作涉及 20 多个机构,并且还在不断增加。8 月 29 日,CubeSat 上的第一个 GRID 探测器被发射到太阳同步轨道,目前正在测试中。通过三角测量和通量调制,GRID 能够以大约 10 度的 90% 误差半径定位像 170817A 这样的微弱 GRB。GRID 由学生提出和开发,本科生的贡献相当大,未来仍将作为学生项目运行。目前的 GRID 合作涉及 20 多个机构,并且还在不断增加。8 月 29 日,CubeSat 上的第一个 GRID 探测器被发射到太阳同步轨道,目前正在测试中。通过三角测量和通量调制,GRID 能够以大约 10 度的 90% 误差半径定位像 170817A 这样的微弱 GRB。GRID 由学生提出和开发,本科生的贡献相当大,未来仍将作为学生项目运行。目前的 GRID 合作涉及 20 多个机构,并且还在不断增加。8 月 29 日,CubeSat 上的第一个 GRID 探测器被发射到太阳同步轨道,目前正在测试中。目前的 GRID 合作涉及 20 多个机构,并且还在不断增加。8 月 29 日,CubeSat 上的第一个 GRID 探测器被发射到太阳同步轨道,目前正在测试中。目前的 GRID 合作涉及 20 多个机构,并且还在不断增加。8 月 29 日,CubeSat 上的第一个 GRID 探测器被发射到太阳同步轨道,目前正在测试中。
