Educational traiming and measure total electron count and photon-entangling payload.


Main objective is for students to understand space technologies and to gain practical experiences while building, integrating and testing 2U CubeSat bus and payloads.

First payload aims to measure the Total Electron Count (TEC) in the ionosphere above Singapore. The second primary payload is the Small Photon-Entangling Quantum System (SPEQS) payload, which is developed by the Center for Quantum Technologies (CQT) in NUS. A compact and efficient system for generating and detecting photon pairs is conducted.

The SPEQS experiment utilizes a process called Spontaneous Parametric Down Conversion (SPDC) to generate entangled photon pairs. The generation and detection of photon pairs are performed within the package to check the quality of the entanglement.
