ESAT is an educational satellite that aims at becoming the perfect tool for hands-on training in space engineering at all levels. The potential users range from elementary schools, where STEM skills development is pursued, to university engineering courses and all the way up to engineering companies. For all of them, this realistic satellite simulator offers a wide variety of education activities.
ESAT has been developed in a way that allows the users to expand it, making it is easy to build on it. ESAT users can integrate and test their own developments, both software and hardware, making it possible to share and exchange new ideas, and to collaborate in new developments. To achieve this objective the subsystem interfaces are provided, along with the ESAT open source code which has been developed using an open source programming environment.
The use of ESAT not only gives the students the opportunity to experience the real performance of the different subsystems in a satellite and the interaction between them, reinforcing their theoretical knowledge, but it also allows the implementation of an education based on practice, making the students the centre of the educational process.
Let us introduce you to ESAT
ESAT is a 10x10x10cm nanosatellite based on the successful CubeSat standard, weighing less than 1kg.
ESAT has the following typical spacecraft subsystems:
ESAT features a Wi-Fi communication system allowing the connection with your PC, where the ESAT GUI allows an easy operation of the satellite.
All the information needed to operate and extend ESAT is available in the set of documentation provided with it.
With ESAT the users can choose to focus and work on each subsystem independently or to practice with the fully integrated satellite.
Electrical Power Subsystem
Attitude Determination and Control Subsystem
Communications Subsystem. Coming soon!
Ground Support Equipment
Command and Data Handling Subsystem
ESAT Graphical User Interface
A router is required to communicate with the ESAT using the WiFi connection. Windows WiFi hotspot connections do not allow the communication with the ESAT, some USB WiFi do allow it though.
The workstations are the computers from which the users control the ESAT unit(s). The minimum requirements for a workstation are:
Connection to WiFi LAN (wired or WiFi).
OS: Windows 7 or above. Windows 10 is recommended. ESAT Ground Segment SW should be compatible with Mac OSX Mavericks or above, CentOS Linux 6.5/6.6/7 and Ubuntu Linux 14.04LTS, but support is not provided.
A USB 2.0 port.
There are no specific requirements to the microprocessor, graphics board, RAM… The Ground Segment SW is very light, i.e. it could run in a raspberry pi.
