Solar sensors

Solar sensor modules addresses are 0х10, 0х11, 0х12 and 0х13, corresponding to 16, 17, 18 and 19 in decimal form.

All solar sensor modules has the same set of commands and responses.

Some commands are similar to commands of other modules, for example:

  • cgf_get_dest_id – setting address for packet receiver;
  • cgf_regular_telemerty_on - setting period for packet sending;
  • request_version – request module firmware version.

However the contents of the data returned will be different: there will be returned data on direction angle to light source: ~10-B21 sun_dir_x, ~10-B21 sun_dir_y, ~10-B21 sun_dir_z.

Set the period 10-A63 cgf_regular_telemerty_on, address 10-A61 cgf_set_dest_id, set flags ~10-B21 sun_dir_x, ~10-B21 sun_dir_z.

At History field there will be displayed the packets received.

Move to Plots field, to Sun Sensor tab.

You shall see the raw-data received. Plot shows the moments of light source brightness’ increase.

Put some light at the solar sensor from one side (approximately 45° to normal), then from other side (approximately -45° to normal). There will be drawn such plot:

It should be noted that Houston SW is not designed for visualization of processed data; it shows all plots in the uttermost raw form. For this case, there shown the relative values of vector projection to x and z.

To calculate the values of angle in degrees you shall process the logs that are stored automatically.
