If you are looking to create a device that can transmit a small amount of telemetry data through satellite communications to a server located in your house, there are a few steps you can follow to get started.

Firstly, it is important to choose the technology that will best suit your needs. While LORA (Long Range) communication technology is an option, it may not be the best choice for satellite communications due to its limited range. Instead, you may want to consider technologies such as Iridium or Globalstar, which are specifically designed for satellite communication.

Once you have chosen the technology, the next step is to find the appropriate development boards or kits that can help you in building your device. Numerous options are available in the market, depending on your specific requirements. These development boards often come with integrated connectivity options and technical documentation to guide you through the process.

When building your device, you will need to consider the hardware components necessary for satellite communication, such as modems and antennas. You may also need to integrate sensors that can collect the telemetry data you want to transmit.

To establish a connection between your device and the server in your house, you will need to set up a satellite communication infrastructure. This may involve registering your device with the satellite service provider and configuring the necessary network parameters.

Once the hardware is set up, you can start developing the software that will allow your device to transmit the telemetry data. This may involve programming the microcontroller or using existing software libraries for satellite communication.

It is crucial to test your device thoroughly before deploying it. This will ensure that the telemetry data transmission is reliable and successful. You may need to perform field testing or simulation exercises to validate the performance of your device.

In conclusion, building a telemetry data transmission device using satellite communications requires careful consideration of technology, selection of appropriate development boards, integration of hardware components, and the development of software. By following these steps, you can create a device that effectively transmits telemetry data from anywhere to your server at home.
