Axon' expertise on board the Teleos-02 satellite

24 Apr 2023

Successful launch for the Indian Space Research Organisation (ISRO) launcher on Saturday 22 April from the Sriharikota spaceport. On board, a satellite developed by ST engineering and equipped by Axon': Teleos-02. The observation satellite will remain in Earth orbit to collect imagery using an ultra-precise synthetic aperture radar. The satellite carries a wide range of Axon' solutions, demonstrating its expertise.

TeLEOS-02 in Earth orbit

The TeLEOS-02 satellite that flew on ISRO's launch vehicle is a 750 kg earth observation satellite equipped with a synthetic aperture radar capable of providing data with a resolution of one metre. It was developed by the Singapore Defence Science and Technology Agency DSTA (representing the Singapore government) and ST Engineering. He will be used to meet the satellite imaging needs of various Singapore government agencies.

Axon' expertise is omnipresent in the satellite, including ESCC compliant wires, miniature connectors (Micro-D and power connectors), MIL-STD-1553 data transmission harnesses, halorings as well as RF cords.

Space-specific constraints

Mechanical and thermal constraints, need for extreme miniaturisation, space projects are particularly demanding. Given the challenges, data transmissions must be extremely reliable, as the slightest failure could lead to mission failure.

Axon' links have been specially designed to meet these constraints, and have also been assembled and tested in clean rooms dedicated to space applications, with conditions that meet the strictest criteria of the major players in the field.

Many projects for Axon'

In the past, ISRO's launcher has already carried large-scale missions for which Axon' has provided solutions such as Chandrayaan-1 and Mangalyaan.  For Chandrayaan-1, Axon' provided ESA wires and data transmission harnesses integrated with the lunar orbiter. For Mangalyaan, the cabling system (cables, couplers and splices) for transmitting data between the probe's electronic equipment was delivered to ISRO.
