Allen Johnson has over 40 years of hands-on experience designing and testing airborne communications systems and satellite communications systems and testing the effects of propagation anomalies on system design. Mr. Johnson has been involved in the development, testing and fielding of military and commercial airborne satellite communications systems including:

• AFSATCOM
• FLTSATCOM
• UHF Follow-On (UFO)
• Space Data System (SDS)
• Defense Satellite Communication System (DSCS)
• Milstar
• Global Broadcast System (GBS)
• Iridium
• INMARSAT

Mr. Johnson also has extensive experience in techniques for designing communications system to alleviate problems caused by:

• ElectroMagnetic Compatibility (EMC)
• Multipath fading
• Ionospheric scintillation fading
• Atmospheric attenuation
• Co-site interference

We can provide tutorial sessions running from one to five day on the following topics:

• Communications satellite terminal design
• Communications test program design
• Propagation problems and mitigation techniques
• Electromagnetic compatibility testing
• Frequency authorization and allocation
