System Overview


Proof of concept: IDRS & Heritage Flight

10

• Conducted in-orbit IDRS testing with an Addvalue designed and built BGAN terminal aboard a LEO satellite operating over the Inmarsat I-4 satellite network

• Over the Inmarsat I-4 satellite network demonstrated good quality IDRS functionality in orbit • Established and maintained 2-way, real-time data sessions • Confirmed Inmarsat BGAN network compatibility

• Gathered useful data for the development of its

commercial version • Link margins and sustained data throughput over the orbit • Antenna pointing regime, GPS receiver operation, and

anomaly detection/recovery methods • Hardware resilience

With over 14 months of operation aboard the VELOX-II, a Singaporean LEO satellite

IDRS Applications & Benefits

NEAR REAL-TIME TT&C • Real-time management of anomalies to extend LEO life

spans

NEAR REAL-TIME TASKING/RE-TASKING • Update of LEO tasking plan in real time

• Shortens time between order and delivery of images

• Surveillance missions; EO missions; Defence missions (responsive space)

COMPLEMENTS THE NEED FOR GLOBAL GROUND INFRASTRUCTURE • Support smaller and cheaper LEO missions that require

near real-time data relay, previously not economically viable due to cost of ground infrastructure / services

NEAR REAL-TIME DELIVERY OF MISSION DATA • Mission data “alerts” – real-time alerts of time critical

observed events (Space / Earth observation).

• Surveillance missions, Defence missions (responsive space)

• Near real time delivery of low volume, high value data (weather, situational awareness data, AIS, ADS-B)

• Near real-time sampling & filtering of mission data – facilitates a significant increase in yield / improved data quality (Earth observation)

LAUNCH VEHICLES/SPACE TRANSPORT VEHICLES • Efficient beyond LOS tele-command / telemetry

communications during launch missions
