This paper presents our work on CubeSat design and development which focuses on JPEG compression and transmission to ground station. And this paper also uses the high altitude balloon to verify CubeSat functions as it is low cost experiments but can provide conditions similar to spacelike: pressure, temperature, air density as well as distance for communication. This paper will discuss the testing result of CubeSat on high altitude balloon to examine functions, verify link budget and signal strength in stratosphere at maximum altitude of 24 kilometers.

This fact has caused satellite developers to establish their own wireless network with a low coverage area that does not function very well. These problems can be resolved by setting up an effective wireless network that can be offered as a service to satellites in orbit. This study is focused on designing a high-quality wireless-in-space network to connect satellites in orbit to the Internet. Such a network would enable satellites to be controlled through the Internet from the Earth without having their own ground stations. In this paper, various aspects of the design of a network setup standard are discussed. These aspects include appropriate wireless communication and the construction of a model satellite that can be connected to the network from space. The work also included testing the design by setting up the Internet network for use above Thailand's territory and launching the original model satellite for the demonstration of the principle. The sensor data was then transmitted in real time to audiences from all over the country and used to design an Internet network in space with global coverage, which is a target for further development.

Keeping in mind the growing trend of international cooperation, GISTDA and the National Space Organization (NSPO) of Taiwan will enter into a cooperation agreement that will develop space system engineering in Thailand. The cooperation aims to promote technical activities, human resources development as well as infrastructure development in both countries. Several cooperative activities had already been initiated according to the work plan and an In-flight Systems Engineering Technical Assistance (SETA) has also been drawn up and agreed upon by both the agencies. The SETA encompasses the area of satellite operation, satellite and ground maintenance, anomaly handling, instrument calibration and satellite life extension assessment. The execution procedure and budget planning has been taken into consideration and the allotment of resources, both time and money, are planned for. GISTDA has also proposed the timeframe for personnel exchanges and training program to NSPO and the work plan will be put into action as soon as the areas are mutually agreed upon. agencies and discuss how cost saving is achieved with the application of communication technologies.
