Orbital Factory 4 (OF-4) Satellite

Demonstrate S-Band communication capability
from apogee of GTO orbit. Measure long-term radiation effects due to electrons & protons in GTO.

Goals:

• Demonstrate S-Band communication capability from apogee of GTO orbit.
• Measure long-term radiation effects due to electrons & protons in GTO.
• Develop and fly novel payloads

Orbital Factory 4 Mission challenges:

• Long distance communication during apogee passes
• Electrical and communication power limitations
• Increased communication losses
• Passage through the Van-Allen belts
• Probability of Single Event Effects
