About
XDSAT M600 is the largest micro-satellite platform in XDLINX Space Labs’ XDSAT family, originally specified for 75-100 kg payloads and, following its June 2026 in-orbit qualification, rated to support missions up to 300 kg. It supports EO optical, SAR, SIGINT, IoT and laser payloads on the Antaris SatOS distributed compute stack across bus, payload edge and SDR, with 3-axis pointing accuracy and stability of ±0.002° (1-sigma) using 2 star trackers. Power is supplied by 600 W solar panels with 1100 Wh of storage, with multiple electric and chemical propulsion systems available. TT&C and software updates run securely via S-band SDR and UHF, with X-band downlink up to 500 Mbps, and ground control through public or private ground stations using Antaris mission control software. In June 2026 XDLINX announced in-orbit qualification of the M600 platform together with a multispectral imaging (MSI) optical payload, entirely built in India, with modular architecture supporting Earth observation, defence, maritime intelligence, climate monitoring, communication and infrastructure analytics applications, assembled and tested with partner Ananth Technologies and with more than 20 satellite missions planned over the following two years.
