Technical specs

DAMA is a channel assignment technology, Demand Assigned Multiple Access, used in Satellite communication. ​

DAMA has the added advantage that it functions on any GEO satellite offering capacity using bent pipe, thus requires no special security or coordination hardware on the satellite.

The services provided are: Speech, Messaging, Data, VoIP, Unicast, Multicast, and Broadcast.

The embedded protocol stack offered by GateHouse can be used by governmental and corporate security organizations within the fields of e.g.

  • Border control
  • Security guards
  • Oil and gas

System overview

GateHouse SatCom offers individual software components like MAC and Control Layer for civil use. The embedded protocol provides a closed system for enhanced security.

The communication system uses UHF band capacity on a geosynchronous satellite where mobile terminals communicate controlled by a Hub also connected via Demand Assigned Multiple Access (DAMA) based scheme.

The MAC layer controls the modem, instructing it to transmit the required amount of data at the specified time. A “DAMA Terminal Controller” component manages this access based on information received on the accessed channel and requests for access from application level software in the terminal.

To accommodate correct transmission timing, the MAC layer takes input from a timing and position source, typically a GPS receiver. Data to and from applications, such as Push-to-talk, Voice, or Short Messages are queued in a Queue Management component, where it is made available for transmission based on priority and Quality of Service (QoS).
