Two payloads have been presented for an experimental and an operational Aerosat system, the latter shared with the maritime service using technology which is available today, the mission requirements being attainable with a reasonable margin for mass and power prior to project start. Three important assumptions have been made. One is the neglect of any improvement in space qualified technology. The second is the use of spot beam maritime services which gives a substantial increase in satellite capacity for a given payload mass and power requirement. The third is the technique of controlling the transmit carrier level according to the ship's position in the satellite antenna beam. These two latter ideas require the ground station to establish a knowledge of the ship's position during the initial contact.
