A study and experimentation on satellite data transmission procedures
Abstract
The results of a design study and experimentation on satellite data transmission at rates from 64 kbps-2 Mbit/sec are reported. The process was targeted at point-to-point communications, implementations with Telecom 1 and determining the highest efficiency and data handling security attainable. Fully duplex links were assumed, along with modulo 8 128 octet/sec data rates. Request by rejection and error recovery by selective rejection were selected for the 64 kbps range to maintain a 90 percent efficiency range. Specific frame repeat requests were necessary for maintaining efficiency at higher data rates. The protocols were implemented using decision tables in ROM chips. Details of the microprocessor architecture are provided. First tests with the system yielded 99 percent efficiency while interfaced with the Telecom 1 spacecraft.
