TIPtoPDT

This script takes the .tip frames from satDump and converts them into a PDT-Telemetry-Explorer compatible format.

Background

NOAA 15/18/19 transmit SEM-MEPED and HIRS data via a direct sounder broadcast (DSB) at 137MHz to the earth. To demodulate and decode this data, Project Desert Tortoise was created. This data is not only transmitted via DSB, but is also part of the HRPT downstream on l-Band. The problem: Desert Tortoise cant handle HRPT. Thats why we use satdump to create a .tip file, which is then transformed into a .txt file using this script and decoded using PDT-Telemetry-Explorer.

Installation

To run this script, you need to have python3 installed and added to PATH. After that, simply run pip install tqdm.

Usage

To decode telemetry from HRPT:

1. Use satDump to decode .tip frames.
2. To transcode TIP minorframes, simply drop the input file named noaa_hrpt.tip into the same directory as the script.
3. Run the script
4. Use PDT-Telemetry-Explorer to decode the created .txt file.
