• Jamia: about Polkadot & JAM
• Spacesharks: about SpaceTech

接著 上一篇 Claw 堆疊筆記 之後，今天把 NVIDIA Agent Challenge 2026 的參賽計畫「Spacesharks Mission Desk」做了一次重要的重整。

題目沒換，stack 沒換，但我把這個 agent 要證明什麼 重寫了一次。

原本的版本是「把現有 Jamia / Spacesharks GPT 移植到 Nemotron stack」。今天的版本是：

一個低成本、多模型、能拿出證據、可以連跑 24 小時的衛星營運 copilot — 它的可信任性不是來自最大的模型，而是來自一個被刻意設計過的 trust stack。

這篇筆記紀錄這次重整的原因、四層信任架構，以及我為什麼把 scope 鎖到只有四個 ingestion source。

Taiwan is nearly a world-class leader in the upstream of the LEO satellite supply chain (RF PA, filters, high-frequency PCB), and has decent participation in the downstream (ground terminals, antennas) — but a structural void exists in the hottest new theme of 2025–2026: mid-stream C, Orbital Data Center (ODC) hardware integration.

This is not an accident. It is a structural opportunity window.

In March 2026, Jensen Huang said something on the GTC stage:

"Space computing, the ultimate frontier, has arrived."

This was not a metaphor. In November 2025, US startup Starcloud launched an NVIDIA H100 into orbit (Starcloud-1) and completed the first large language model training session in space. Two months later, on January 11, 2026, Axiom Space launched two orbital data center nodes (ODC Node 1 & 2), connected them to Kepler Communications' optical relay network, and began offering cloud compute services to external customers.

Earth orbit has officially become a new location class for data centers.

The traditional space industry has a simple answer to radiation: test everything, apply twice the design margin, and only use military-spec parts.

That approach made sense when launching a billion-dollar GEO satellite. It makes much less sense when you're a New Space startup trying to ship a CubeSat in nine months on a shoestring budget.

This post captures my current engineering thesis across AI systems, space infrastructure, blockchain, and RF validation.
