How To Fix cassbeam: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu cassbeam is provided by cassbeam package.

cassbeam is:

Cassbeam is a Cassegrain antenna ray tracer. A Cassegrain antenna is a double reflector system which works on the principle of cassegrain optical telescope. A high gain cassegrain reflector antenna in Ku-band has been successfully developed for command transmit application for the missile programme. It can also be used for monopulse radar, satellite communication.

Based on an input text file, it computes several properties of the antenna including gain, zenith system temperature, and the beam, in full polarization. All calculations are done in the transmit sense and use reciprocity to relate to the equivalent receiving system.

Additionally, cassbeam allows deformations, or pathologies of the optics to be modelled. Currently this is limited to rotations and translations of the feed and secondary. In the future, large scale deviations in the primary (such as a misplaced panel) will likely be supported.

To fix this problem, we can install more using the command below.

sudo apt-get -y install cassbeam

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install cassbeam.

sudo apt -y install cassbeam

Or if you have aptitude installed you can use the following command.

sudo aptitude install cassbeam
