Mission

The Colorado Student Space Weather Experiment (CSSWE) is an NSF-funded 3U CubeSat (30×10×10 cm) which houses an energetic particle telescope. The Relativistic Electron and Proton Telescope integrated little experiment (REPTile) will provide directional differential flux measurements of high-energy electrons and protons. The CSSWE mission goals are:
* Develop a student-designed CubeSat system for space weather investigation
* Understand the relationships between solar energetic protons (SEPs), flares, and coronal mass ejections (CMEs)
* Characterize the variations of the Earth’s radiation belt electrons

Telemetrie

During the first month after orbit insertion, CSSWE will transmit a beacon once every 18 seconds.Download Original Decoder Software

Serial Port to TCP Socket Forwarding – This program forwards all serial data to an internet-enabled TCP socket. This software should reside on the computer physically connected to the TNC. All incoming data is stored locally if an internet connection is not available.This program is based on example code provided by the pySerial project. It is released under the free Python License. Supported Operating Systems: Windows, Mac OS X, Linux Beacon Decoding Client – This program listens to the serial socket and displays interesting telemetry from any received beacons. Data points include: voltage levels, input power, satellite state, temperature, and many more….
Supported Operating Systems: Windows, Mac OS X, Linux

CSSWE Telemetry Decoder

CSSWE sendet aller 18s einen 9k6 Datenburst (RAW DATA). Der TNC muss sich daher im KISS Mode befinden. Zur Dekodierung dieser Daten wird ein Standard-KISS File benötigt. Es werden ausgewählte Telemetriekanäle angezeigt und graphisch dargestellt.
Zusätzlich wird ein CSV File mit allen Telemetriewerten wird erzeugt.
