The PSLV C29 Mission carries six satellites for Singapore including commercial and university satellites of different sizes and application. The primary payload of the launch is the 400-Kilogram TeLEOS-1 Earth Observation Satellite that will deliver remote sensing products of Earth’s equatorial regions for the commercial market. TeLEOS-1 is joined by two microsatellites in the 80 to 125-Kilogram mass range and a group of three small CubeSats. The C29 mission is targeting a circular orbit 550 Kilometers in altitude, inclined 15 degrees.


TeLEOS-1 is Singapore’s first commercial Near Equatorial Orbit (NEqO) Earth Observation Satellite, built by ST Electronics and operated by Agil Space to deliver one-meter resolution imagery of Earth at an exceptionally high re-visit rate of 12 to 16 hours to bring to users a unique capability of accessing temporal imagery of time-sensitive events.

The spacecraft has a liftoff mass of 400 Kilograms and hosts an electro-optical imaging instrument. The instrument covers a 12 by 12-Kilometer swath at nadir and achieves a ground resolution of one meter in the panchromatic band.

Kent Ridge 1

Kent Ridge 1 is a microsatellite mission developed and operated by the National University of Singapore, carrying a hyperspectral imaging payload for remote sensing. The primary objective of the mission is the demonstration of a Visible, Near-Infrared, Short-Wave Infrared Fourier Transform Recovery Instrument integrated into a microsatellite bus for a number of applications focused on the monitoring of land, water and vegetation as well as disaster monitoring and management.

VELOX-CI is a 123-Kilogram satellite built and operated by Nanyang Technological University in Singapore to deploy a GPS occultation payload into orbit for studies of atmospheric properties and to act as a tropical weather satellite. Monitoring changes in GPS signals when Earth’s atmosphere is within the line of sight between the spacecraft and the GPS satellite allows a number of properties to be calculated, permitting a three-dimensional profile of the atmosphere to be generated.

Galassia is a 2-Unit CubeSat developed by students at the University of Singapore with the primary objective of acting as a hands-on project for students to learn about the conduct of a space mission from development through operation in orbit. Two payloads are part of the satellite, a Total Electron Counter and a Small Photon-Entangling System instrument for the correlation of quantum data to gather information for the concept verification of quantum-based communications.
