WHAT IS IRIDIUM PRIME?

Transcription

1 WHAT IS IRIDIUM PRIME? Iridium PRIME / EuroPRIME is a payload accommodation service that leverages the Iridium NEXT spacebased global mesh network, ground infrastructure, and flexible bus design. 1 Iridium will launch additional spacecraft with customer payloads into orbits that can communicate through the Iridium space-ground network.

2 IRIDIUM BLOCK 1 VS. IRIDIUM NEXT VS. IRIDIUM PRIME Iridium Block 1: Original Network; FOC Nov 98; constellation of 66 satellites = still healthy and performing well Iridium NEXT: Scheduled for launch totalling 72 satellites including 6 in-orbit spares Replenishes and updates current Block 1 constellation Iridium / EuroPRIME: Early launch possibilities Adds as many as 66 additional satellites to provide payload accommodation services EuroPRIME activities centred in the UK 2

3 Payload and Bus Specification Payload Weight Payload Dimensions Payload Power Payload Data Rate (Inter-satellite Links) Payload Data Rate (Feeder Links) Specification 210 kg Two Payload Volumes with Nadir View 650 Watts (1100 W peak) 1 Mbps; Surge up to 8 Mbps Latency less than 0.5 seconds typical Up to 15.5 Mbps within Range of Ground Terminal Bus Expected Lifetime Orbit 12.5 Years 780 km Altitude 86.4 o Inclined 6028s Period

4 Euro PRIME TURNKEY PAYLOAD ACCOMMODATION 4 Euro PRIME can provide a turnkey payload accommodation service with: Standard interfaces on a commodity bus platform derived from the Iridium NEXT program Established Iridium global mesh network for payload connectivity Existing ground infrastructure and experienced satellite operations team Single payload or consolidated (multiple) payloads TAS-UK will integrate payload onto satellite

5 PAYLOAD VOLUME FOR FALCON 9 LAUNCH 5 Up to 10 vehicles per Falcon 9 Possible alternative small launchers For dedicated launch = overall design compatible with Vega fairing

6 IRIDIUM PRIME / EUROPRIME BENEFITS 6 Economic use of spacecraft bus from an active production line Instant command, control and communication of mission data through space-based global network of cross-links Experienced Iridium constellation operations team drive satellite bus and network management Customer commands and processes payload information independently from the spacecraft command and control Rapid Competitively priced Turnkey solution available Rapidly and readily available data

7 APPROACH 7 Customers will use the PRIME service to: Procure and operate on-orbit payload mission capabilities Integrate space and ground system network services for payload command and data handling Deliver payload data to the end-user customer Step 1. Complete payload questionnaire about payload size, weight, power, data throughput and operational concept. Step 2. Complete customer-funded study to solve specific topics of accommodation design. Step 3. Sign hosting agreement and data transmission services agreement.

8 POTENTIAL APPLICATIONS FOR IRIDIUM PRIME / EUROPRIME 8 Prototype Demonstrations Government and Commercial Missions Earth Observation Terrestrial & Space Weather Observation Scientific & Climate Monitoring Advanced Broadband Services Automatic Identification Services Communications Systems Precision Timing and Location Services Asset Tracking Inter-satellite Control and Data Links Space Situational Awareness

9 EUROPRIME SUMMARY 9 Turnkey payload missions can be launched Commodity Bus from an active assembly line is a costeffective solution for multi-payload missions Payload accommodation can be adjusted for mission Customer maintains payload control using Iridium intersatellite links and teleport network Experienced Iridium operations team will operate and manage the satellite bus and network Incremental deployment options offer flexibility over payload development, schedule, and operations
