This repository contains NASA's Telemetry Output Lab (to_lab), which is a framework component of the Core Flight System.
This lab application is a non-flight utility to downlink telemetry from the cFS Bundle. It is intended to be located in the apps/to_lab subdirectory of a cFS Mission Tree. The Core Flight System is bundled at https://github.com/nasa/cFS (which includes to_lab as a submodule), which includes build and execution instructions.
to_lab is a simple telemetry downlink application that sends CCSDS telecommand packets over a UDP/IP port. The UDP port and IP address are specified in the "Enable Telemetry" command. It does not provide a full CCSDS Telecommand stack implementation.
To send telemetry to the "ground" or UDP/IP port, edit the subscription table in the platform include file: fsw/platform_inc/to_lab_sub_table.h. to_lab will subscribe to the packet IDs that are listed in this table and send the telemetry packets it receives to the UDP/IP port.
As a lab application, extensive testing is not performed prior to release and only minimal functionality is included.
