Attached is a java application that can be used to decode telemetry found in your downlinked file: beacondecoder.jar

Usage (for Caerus Telemetry in "file_name.txt"):

C:\> java -jar BeaconDecoder.jar file_name.txt

Also attached is some sample beacon data that you can use to test this out, here: beacon_data.txt

Listed below are the parameters to de-code the CAERUS Beacon telemetry packet information upon recieving it (manually as opposed to the JAVA script file).

Note: there cannot be any gaps in the telemetry string, such as new lines or carraige returns.

Please send RAW temetry information recieved to the following e-mail with "Pass" in the title of the e-mail: caerus@astronautics.usc.edu
