What You’ll Need A HackRF, LimeSDR, BladeRF, or PlutoSDR. These SDRs can transmit. If using a HackRF, make sure you have a TCXO (Temperature Controlled Crystal Oscillator). A Linux VM or Host. Note: Both flags on this project can be found without using an SDR, but without an SDR with…
The Two Line Elements or TLE format is the standard way to describe satellites in orbit above Earth. Understanding the TLE format allows users to make predictions about future or past satellite passes. The simplest way to think of a TLE is as a description of an orbiting object’s motion…
Decoding a BPSK Signal Binary phase shift keyring or BPSK is the simplest form of digital phase modulation. Depending on the phase of the signal, the hardware or software decodes a zero or one. In this exercise dervied from the DoD Hack-A-Sat challenge, Phasor, you will decode a BPSK signal…
