@orbpro/plugin-sgp4

OrbPro SGP4/SDP4 Orbital Propagator Plugin.

Implements the SGP4 and SDP4 algorithms for propagating satellite state vectors from Two-Line Element (TLE) sets. Compiled to WebAssembly for high-performance, cross-platform use.

Installation

npm install @orbpro/plugin-sgp4

This package is intended to be used within an OrbPro workspace or alongside the OrbPro engine. Standalone use requires the OrbPro plugin-sdk.

Building

Build the WASM artifact using the OrbPro plugin-sdk:

# From within the OrbPro plugin-sdk workspace:
npm run build:sgp4
# Output: dist/sgp4.wasm

Usage

Via SDN Plugin Delivery (ecies-decrypted bytes)

import { createSGP4Propagator } from "@orbpro/plugin-sgp4";

// wasmBytes are delivered pre-decrypted by the SDN plugin-delivery system
// (ecies-x25519-hkdf-sha256-aes-256-gcm)
const propagator = await createSGP4Propagator({ wasmBytes });

Direct / Development

import { createSGP4Propagator } from "@orbpro/plugin-sgp4";

// Without wasmBytes, loads raw WASM from dist/sgp4.wasm
const propagator = await createSGP4Propagator();

Options

Option	Type	Description
wasmBytes	Uint8Array	Pre-decrypted WASM bytes from the SDN delivery system.
decryptFn	Function	Legacy AES-256-GCM decrypt function (protection-runtime).
lowMemory	boolean	Use reduced memory configuration.
