KNACKSAT (KMUTNB Academic Challenge of Knowledge SATellite) is a 1U-CubeSat satellite (roughly 10x10x10 cm, 1.3 kg) 
designed and developed by King Mongkut’s University of Technology North Bangkok (KMUTNB).
The satellite uses amateur radio frequencies for the communication between the satellite station and the ground station. The objectives of the KNACKSAT project can be categorized into educational objectives and technology demonstration objectives. In term of the educational objectives, the project will enhance the knowledge and experiences in satellite design and construction. These can be considered as fundamentals for development of larger satellites in Thailand in the near future. Apart from these, the project provokes the interests in science and technology of young Thais. 
For the technological objectives, the main missions of KNACKSAT include :
(1) developing a communication system using armature radio frequencies
(2) taking images from space
(3) testing 3-axis attitude control algorisms by using magnetic torquers
(4) verifying a deorbit technology by a magnetic torque
(5) confirming the uses of Commercial Off-The-Shelf (COTS) components in space. 


The in-house satellite fully developed in Thailand, KNACKSAT, consists of six subsystems:
1. Structure Subsystem, STR
2. Communication Subsystem, COM
3. Electrical Power Subsystem, EPS
4. Command and Data Handling Subsystem, CDH
5. Attitude Determination and Control Subsystem, ADCS
6. Camera Subsystem (or Payload), CAM

Amateur Radio

Although we lost contact with KNACKSAT, the expected information of the satellite are International Designator = 2018-099D and NORAD Catalog Number = 43761.
KNACKSAT utilizes amateur radio frequencies for the communication system. Therefore, we serve the amateur radio community as part of our mission. The information of IARU Amateur Satellite Frequency Coordination of KNACKSAT can be found here.


KNACKSAT was successfully launched with Spaceflight’s first fully dedicated rideshare mission, SSO-A SmallSat Express, on December 3rd, 2018 aboard a SpaceX Falcon 9 out of Vandenberg Air Force Base in California (see the launch).
