What is DAMA?
• Demand Assigned Multiple Access
•New UFO satellites are expensive. DAMA (Demand Assigned Multiple Access)
was a way to increase the number of SATCOM users with the current satellite
resources instead of launching higher capacity satellites. DAMA SATCOM is
designed to replace much of the dedicated UHF SATCOM usage. Its primary
purpose is to increase loading of UHF SATCOM channels by assigning channel
space as demanded by users. In other terms, DAMA allows multiple users to
share a single satellite channel at the same time without interfering with each
other.
• Older radios were upgraded with DAMA capabilities and DAMA Control Stations
were setup. Nothing had to be changed on the current UFO satellites, just some
channels were now designated as DAMA only.
• Demand Assigned: Channel space is assigned as demanded by the user.
Upon completion of communications, the channel space can be assigned to
other users.
• Multiple Access: Multiple users can access the system at the same time.
Access is determined by priority and resource availability at the time of the
request.
• DAMA provides a five-fold increase in voice access using DAMA as opposed to
non-Dama systems. DAMA users must use ANDVT or KG-84 to get 5 users on a
25 kHz channel, not VINSON.
