Broadband VSAT Services- New Perspective for Oil and Gas Applications Saudi Aramco Company, Saudi Arabia The Oil and Gas Satellite Communications 1
Objectiv Explain why VSAT Satellite network is important to Oil & Gas operations Introduce VSAT open standard technology, DVB-RCS Highlight Oil & Gas industry as a potential market for VSAT Communications Highlight challenges facing DVB-RCS Technology 2
Oil & Gas Operatio Communication System are needed to: - Perform real time data monitoring & applications - Perform the daily operations and activities - Improve safety of personnel & assets Onshore Rigs Offshore Rigs & Platforms Seismic Explorations LAN Internet Data/Voice Video Applications Marine Vessels Refineries & Bulk Plants 3 Oil Tankers
Independent from Terrestrials Independent from the environment Services without limitation of: Distance Geographic areas Locations Number of sites Fast deployment Cost-Effective Options : 2-Way VSAT Sate System Microwave Repeaters Satellite Repeater in the Sky Earth Coaxial or Fiber Optic Cable Onshore Rigs LAN Internet 4 Data/ Video Voice
What is VSAT DVB-RC DVB = Digital Video Broadcast RCS = Return Channel via Satellite Open standard VSAT technology ETSI Standard EN 301 790 established for interoperable VSAT networking in 2001 as worlds first two-way satellite standard There are approximately 100 fully compliant DVB-RCS Hubs & 20, 000 terminals worldwide Satlabs: Forum led by ESA grouping stakeholders of DVB-RCS (over 20 members) to ensure standard compliant & interoperability DVB-RCS Availability: DVB-S DVB-S2 5 http://satlabs.org
Why Use DVB-RCS Open Standard IP based VSAT Technology: - Forward data link from gateway to remotes up to 80mb/s - Return data link from remotes to gateway 2 4 mb/s - Multi-vendor competitive environment - Proven Interoperability which leads to low cost equipment - Ease of adding new terminals to network &, Scalable Hub - DVB-RCS supports current and upcoming IP services Fading & Interference countermeasures - Higher availability of terminal connectivity - Optimized use of satellite bandwidth Advanced Coding Schemes - CCM Constant Coding Modulation - VCM Variable Coding Modulation - ACM Adaptive Coding Modulation DVB-S2 Latest Platform Technology 6
DVB-S2: Leading DVB RCS Technology (ETSI: EN 302 307) Wide range of modulation schemes (QPSK, 8PSK, 16APSK and 32 APSK modulation) Variety FEC coding (LDPC): 1/4, 1/3, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10 Supports 3 modes of modulations: CCM/VCM/ACM Provides Ability to Dynamically Change Modulation: VCM/ACM Improves BW efficiency by 30% - 50% over DVB-S in CCM 7
