\subsection{Processing Pipeline}

ZooSat operates as a continuous processing pipeline on the Zoo Network:

\caption{ZooSat processing pipeline stages.}
\label{tab:pipeline}
\begin{tabularx}{\textwidth}{@{}lccX@{}}
\toprule
\textbf{Stage} & \textbf{Frequency} & \textbf{Latency} & \textbf{Description} \\
\midrule
Ingest & Continuous & < 6 hours & Download Sentinel-2 L2A products from Copernicus \\
Preprocess & Daily & 2 hours & Cloud masking, atmospheric correction, mosaicing \\
Detect & Weekly & 4 hours & Run TSN on updated temporal sequences \\
Analyze & Weekly & 1 hour & Compute HFI, classify changes, priority ranking \\
Alert & Weekly & < 1 hour & Generate and distribute alerts \\
\bottomrule
\end{tabularx}
\end{table}

\subsection{Computational Requirements}

\begin{table}[H]

\caption{Computational resource requirements.}
\label{tab:compute}
\begin{tabular}{@{}lcr@{}}
\toprule
\textbf{Stage} & \textbf{Hardware} & \textbf{Cost/Month} \\
\midrule
Ingest + Preprocess & 8-core CPU, 64 GB RAM & \$240 \\
TSN Inference & 4x NVIDIA A100 & \$4,800 \\
HFI Computation & 16-core CPU, 128 GB RAM & \$480 \\
Alert System & 4-core CPU, 16 GB RAM & \$60 \\
Storage (1 PB/year) & IPFS + Filecoin & \$1,200 \\
\midrule
\textbf{Total} & & \textbf{\$6,780/month} \\
\bottomrule
\end{tabular}
\end{table}

At \$6,780/month for monitoring 2.4 million km$^2$, ZooSat costs approximately \$0.003 per km$^2$ per month, an order of magnitude less than manual monitoring through ranger patrols (\$0.05--0.50 per km$^2$ per month depending on terrain).
