ARGOS project - Location and data collection program design of the TIROS-N random access system
Abstract
The ARGOS system provides a means for locating and collecting data from fixed or free-floating buoys, balloon platforms, and terrestrial fixed platforms. The salient feature of the system is the use of a large number of low-cost platforms with only a one-way uplink, platforms to satellite. The present communication shows how the phenomenon of random signal access at the input of the satellite is taken into account in the design of the on-board subsystem to meet global performances. Several identical data recovery units ensure the simultaneous processing of messages. A control unit is implemented to assign the available data recovery units to the random input signals; its algorithm is designed to reduce mutual interference effects between messages.
