Uses

Direct Use

Quick summarization of satellite orbital states for analysts
Plain-language TLE explanations for educational purposes
Offline dataset labeling (orbital classifications)

Downstream Use

Combine with SGP4 for enhanced position forecasting
Integration into satellite autonomy stacks (cubesats, small-scale hardware)
Pre-prompted agent support in secure orbital management workflows

Out-of-Scope Use

High-precision orbit propagation without additional physics modeling
Applications related to targeting, weapons systems, or lethal autonomous decisions
Jurisdictions prohibiting ML or data export (verify with ITAR/EAR guidelines)

Bias, Risks, & Limitations

Category	Note
Data bias	Trained primarily on decayed objects (`DECAY = 1`), possibly underestimating longevity for active satellites.
Temporal limits	Operates on snapshot data; does not handle continuous high-frequency time-series.
Language	Supports explanations in English only.
Accuracy	Potential inaccuracies in decay date predictions; verify independently.

Recommendations

Incorporate independent physics-based validation before operational use and maintain a human-in-the-loop for any critical or high-risk decisions.

How to Get Started

python

from transformers import AutoTokenizer, AutoModelForCausalLM, pipeline
from peft import PeftModel

base = "Qwen/Qwen1.5-7B"
lora = "jackal79/tle-orbit-explainer"

tok   = AutoTokenizer.from_pretrained(base)
model = AutoModelForCausalLM.from_pretrained(base, device_map="auto")
model = PeftModel.from_pretrained(model, lora)  # merges LoRA

pipe = pipeline("text-generation", model=model, tokenizer=tok, device=0)

prompt = """### Prompt:
