Aeneas Telemetry

Aeneas is still on orbit as of January 2018, transmitting a beacon code every 60 seconds roughly. You can download the beacon analog signal using your RF equipment and decode the packets with a decoder provided here:   AeneasDecoder


A sample packet is shown below for illustration. The ASCII characters represent hexadecimal digits. The bit patterns encoded by these digits are interpreted based upon their position in the packet.

The first six bytes represent a marker token that signals that a packet follows, and is associated with the AENEAS satellite.  For Aeneas however, the word "CAERUS" is used. (CAERUS is the name of the previous spacecraft the flew prior to Aeneas, see Caerus on the Nanosatellite page for more information.) This marker will always be 434145525553, or "CAERUS" represented in ASCII. The final two bytes of the packet are a checksum, where the decoder calculates the checksum and compares it to this value to validate that the data packet is correct.
