Abstract

The primary objectives of the project are to build a complex antenna rotation facility that will enable the structure to perform in situ interferometric measurements. The objectives include the construction of a stable frame to support and protect the control electronics, the design and fabrication of a 2.4GHz DTMPA (Dual Triangular Microstrip Patch antenna), and the support of the control electronics with the appropriate software background. The finished structure is capable of tracking the orbit of a satellite of your choice, up to NAP orbit depending on the configuration. The implementation can be divided into four steps. First of all, a sufficiently solid frame was designed and built. From the point of view of the use of materials, LEGO construction toys are the right choice, both in terms of weight and strength. The second step is to design and build the DTMPA. This is followed by the selection and implementation of the appropriate control electron ics. The stepper motor must have adequate torque to ensure proper rotational motion, and the motor and microcontroller must provide clear instructions to the motors. Finally, the code responsible for controlling the motors must be written and implemented in the microcontroller so that the structure can be controlled by the appropriate external computer.
