Abstract

Low earth orbit satellite systems for low-speed data communications have been proposed - the so- called "Little Leo" systems. Dam transmissions on the uplink consist of short (400 ms) bursts of data sent in time slots. Each burst is sent on a frequency which is randomly picked from a bank of available frequencies.
