*.scr - These are scripts on the ground station computer with
commands to perform the usual housekeeping functions, or other list of
commands, in sequence. Generally, all commands to the spacecraft are
incorporated into scripts.
[Day Month Year HH:MM:SS] - The local date/time of the when the command was initiated (Pacific Time).
c - Command to request a "connect" to the satellite. This is done first at each session as a "trigger" for the following commands. Basically, this is just a test that the link is established.
mloadc - Upload a software image. This continues the upload process to send new software to the spacecraft from the ground.
mloads - Upload a software image. This starts the upload process to send new software to the spacecraft. It also sets up a database of what information was successfully uploaded so that all the software can be transmitted even if it requires multiple satellite passes. Typically, this is done in four "chunks" of software, each of which is a maximum of 128 blocks.
s - Download a telemetry "snapshot." That is, it requests the satellite to download the most recent telemetry record that it has in its buffer. Follow the snapshot link to a tabular format of the telemetry snapshot. These include elapsed time of the processor, identification of the processor (or whether the spacecraft is running on an uploaded o/s), last time of an EDAC (error-detection-and-correction memory) error, spacecraft temperatures, spacecraft bus voltage, battery voltages (including cell voltages), currents and charge state, and solar panel currents (for eight of the solar panels).
slc - status log clear. Clear (erase) the memory of on-board telemetry records. These are stored in FLASH memory which is non-volatile, i.e., not erased in the event of a power cycle or reset.
slg - status log get. Start download of all stored telemetry records.
