摘要

The success of Kayser-Threde's test satellite MAQSAT-B2 for L521 (2nd Ariane 5 ECA qualification flight in February 2005) which was equipped with experiments, sensors and an autonomous telemetry system has led to the development of a new experimental platform called KAP (Kayser-Threde Arianespace Platform) allowing an efficient access to space for technology in-orbit verification and small scientific experiments. KAP contains a fully autonomous experiment infrastructure, power and telemetry unit as a kind of complete package or kit to be mounted on a payload bay structure like a raising cylinder underneath the ACU of Ariane 5 using remaining payload capacities of the launcher. As a piggy-back solution in the launcher payload bay KAP will remain attached to the upper stage after primary passenger separation. Although being flexible in terms of e.g. possible payload to be accommodated and number of needed batteries, the whole KAP with a standardized raising cylinder shall be trimmed in such a way to have identical mechanically and dynamically properties each time to be finally like a black box easily to be adapted to the launcher payload configuration for the launcher authority increasing significantly the chance of a recurrent flight opportunity. As a result of a Phase A study co-funded by DLR in the frame of its OOV program, three baseline mission scenarios have been defined: 3 hours (to monitor online experiments / technology demonstrators exposed to the launcher environment), 3 days (starting after upper stage passivation) for short experiments and 1 year. The technical concept for both mechanical and electrical subsystems is mainly based on existing and flight proven technologies from MAQSAT-B2 and Kayser-Threde's successful sounding rocket program TEXUS/MAXUS. Especially the data acquisition and telemetry unit as heart of the KAP experimental payload infrastructure is adapted from these programs to the specific mission needs. The KAP basic concept provides an auxiliary payload mass of up to 220 kg on Ariane 5 to GTO leading to favorable launch costs for the experimenters. A Demonstrator Mission on Ariane 5 is under detailed investigation for an envisaged launch in 2008. KAP on VEGA for LEO applications is the next step to adapt the concept to other members of the European Launcher Family (including SOYUZ). Especially for VEGA it is planned to stabilize the platform by simple means providing an optimum environment for microgravity experiments. Besides the basic concept of KAP the complete KAP program has been developed to provide sufficient flexibility to be mounted also on other structures, like ASAP5 or future single flight opportunity events. Main idea is to standardize the interfaces to the auxiliary payloads and to leave the responsibility to find a flight opportunity to Kayser-Threde as system integrator which allows for a reliable planning for the experimenters aiming for a ticket in the frame of the KAP program.
