RSAT Satellite

default

Purpose

RSAT is conceived to support the national cause of coastal surveillance and harbor traffic management.

Hardware

RSAT is a 3 axis stabilized agile nano satellite weighing 10 Kg and measuring 300mm x 300 mm x 300mm in size with deployable solar panels generating 45 watts solar power.
Software
Algorithms are being developed to resolve collision of signals received by satellite.

Operation

RSAT picks up AIS signals transmitted by ships over a large area on high seas and transmits them to ground station where the signals are processed and the data of the ships in visible area is extracted. The satellite payload receives AIS signals transmitted by ships in VHF band, stores onboard and transmits to ground station in X-band through a high gain phased array antenna during ground station visibility period. Satellite with S-band omni antenna system supports TTC. Onboard control system with four reaction wheels and three magnetic torquers controls the satellite for sun tracking to generate maximum power and also track ground station for data transfer during ground station visibility period.

Student Learning Outcomes

Satellite technology is a multi disciplinary area for study. At CRSST Students work on satellite subsystems that include: telecommand, telemetry, communication systems, power generation, storage and distribution architectures, control systems, Attitude and orbit determination, mechanical design, integration and testing, and satellite control station. The concepts students study in class are seen practically and they gain hands on experience.

Project Update

Student team members can email about what he/she learnt, if we can have one such quote every week the micro-site will reflect the dynamism of the center.
