• Generate detailed technical reports and regulatory filings in compliance with ITU requirements.  Compile and prepare all necessary documentation for ITU filings, including coordination requests, frequency assignment notices, and satellite network filings(including AP30/30A/30B)
• Ensure accuracy and completeness to facilitate smooth processing and approval by the ITU Radio communication Bureau.

• Technical Support:

• Provide expert technical support during the design and implementation phases of satellite communication systems.
• Conduct field measurements and tests to validate link budget predictions and system performance.

• Link Budget Calculations:

• Perform detailed link budget analysis for Ka/Ku band satellite communication systems, considering factors such as EIRP, G/T, antenna gain, polarization, and atmospheric attenuation.
• Utilize advanced software tools for accurate link budget calculations.

• Training and knowledge Transfer:
• Develop and deliver training programs for clients to ensure they achieve operational independence in satellite coordination and link budget analysis.
• Create training materials, including presentations, manuals, and hands-on exercises.
• Prepare and deliver detailed presentations and workshops on satellite coordination and link budget analysis.

WORK EXPERIENCE REQUIREMENTS:

• Minimum of 10 years of experience in satellite communications, with at least 5 years in ITU satellite coordination.
• Proven expertise in link budget analysis for Ka/Ku band frequencies.
• Prior experience managing and overseeing satellite coordination and link budget projects from inception to completion.
• Experience working in a customer-facing role within the defense sector is highly desirable.
• Demonstrated ability to manage complex projects and coordinate with international stakeholders.

QUALIFICATION & EDUCATIONAL REQUIREMENTS :

• Bachelor’s degree in Electrical Engineering, Telecommunications, or a related field.
• Advanced degree preferred.

PREFERRED SKILLS :

• In depth knowledge of satellite communications systems system architecture, including satellite transponders, ground station equipment, modems, and network management systems particularly in the Ka/Ku band. Proficiency in ITU regulations and coordination processes.
• Ability to interpret and apply ITU rules for coordinating frequencies to avoid interference, conducting compatibility analyses, and negotiating coordination agreements
• Expertise in interference analysis and mitigation strategies.
• Comprehensive understanding and expertise in link budget analysis for Ka/Ku band satellite communications, encompassing all relevant parameters such EIRP, G/T, FSPL, rain attenuation, and system availability.
• Knowledge of modulation and coding schemes (e.g., QPSK, 8PSK, 16APSK, DVB) to maximize throughput and link robustness.
• Familiar with UHF spectrum coordination and systems.
• Good knowledge of several of the following satellite software :

• Space Cap & ITU BR IFIC (International Frequency Information Circular)
• Radio Regulations and Rules of Procedure Database (RRS) SRS (Space Radiocommunication Stations) Database
• SatMaster (or equivalent link budget analysis tool)
• Spectrum-E (or equivalent interference analysis tool)
• STK (Systems Tool Kit)
• GIMS (Graphical Interference Management System)

• Languages:

• English mandatory
• Arabic and/or French may be helpful

• Soft Skills:

• Excellent communication and presentation skills.
• Ability to work effectively under pressure and manage multiple priorities.
