trusat-orbit

This repo supports the analyses of IOD/RDE/UK positional formatting formats and generation of TLEs at http://TruSat.org/

Currently, its orbit determination code is based on a Python port of Scott Campbell's C++ satfit code base. After initial prototyping, it is an aim of this repo to include OREKit and related tools for more advanced processing of orbit-related calculations.

Getting started with TruSat-orbit

First, we recommend setting up a python virtual environment

git clone https://github.com/consensys-space/trusat-orbit.git
cd trusat-orbit
pip install -r requirements.txt
python satfit.py

iod.py - Utilities for importing, validating, and operating on IOD/RDE/UK positional formatting formats
tle_util.py - Utilities to import, export, validate and operate on Two-Line Element sets
satfit.py - Suite of utilities based on and extending Scott Campbell's C++ satfit code base for reading visual observations and updating TLEs
- satid.py - Search TLE catalog for possible match to an UNIDentified satellite TLE
- elfind.py - Generate a provisional TLE from 2-3 IOD records

Tests - Unit tests for the above

tests_iod.py
tests_satfit.py
tests_TLE.py

Dependencies

This codebase incorporates an updated and cython-accelerated version of python-SGP4, from the branch python-sgp4/cython-7-dec-15-vallado

Coding Style
