"Houston" SW interface

Below there is a description of «Houston» SW Interface.

Menu allows to switch on such windows:

  • List of devices, parameters and commands (Tree);
  • Hexadecimal presentation of received data (HexView);
  • Command Queue (Queue);
  • History (History);
  • Fileds (Fields);
  • Data output (Output);
  • Comand repeating (Repeat).

List of devices

List (tree) of devices descripts the organization of space vehicle, including all commands and return parameters. Every device name starts with its hexadecimal address. Return parameters starts with tilde. At Figure presented all commands and parameters for flywheel with 0xА address.

Information packets contents

At Fields field there presented all fields for chosen parameter, for example: on chosing ~A-AD1 regular_velocity parameter there will be displayed fields float_val, temperature, invalid и counter.

Command sending

Before sending the commands to devices via VHF you should chose VHF channel in device configurations.

For the flywheel, you should:

  • Choose parameter А-А61 cfg_set_dest_id
  • Set id to value 1
  • Press To server

At history window there will be displayed heartbeat packets.

Now we can send the command to reaction wheel via VHF. Let’s set the reaction wheel’s rotation rate as 1500 rpm; to do so, send the command that changes its rotation rate A-A01 rpm.

  • Choose command A-A01 rpm
  • Enter into input field value for rate, for example 1500 rpm
  • Send the message to server pressing To Server button

Also at the plot will be displayed the points showing flywheel’s rotation rate. And in the history window will be displayed the received data.

It is possible to draw 6 plots with such parameters:

  • Euler angles
  • Angular velocity sensor
  • Magnetometer
  • Power system
  • Solar sensors
  • Flywheel

Plot Configuration section has 4 items:

  • Disable – switching the plot on and off
  • Add – adding new scale to plot window
  • Panel – plot panel export
  • Plots – autoscale switching on

Window for adding new scale to plot
