TEXUS and MAXUS payloads are currently providing 12 bit analog channel accuracy for their data acquisition chains with different signal conditioning elements such as temperature measurement, strain gauge, pressure measurement channels, and general purpose amplifiers. Transient recording functions are rather seldom as all data is directly transmitted via PCM to the ground station. However, the user requirements are steadily increasing in terms of accuracy, data security, and high data throughput rate with an ever increasing number of telemetry channels. The newly developed Kayser-Threde telemetry and telecommand system CTS 3000 (Compact Telemetry System) fulfils these requirements by providing up to 16 bit accuracy for its analog channels with a sampling rate up to 2 kHz (at this accuracy), on-board transient memory to protect against data loss and provides an integrated telecommand decoder at the same time, reducing the necessary amount of equipment used for instrumentation. The equipment further reduces the necessary effort for refurbishment because of its internal self calibration over the full environment temperature range. On top of its IRIG PCM interface the system is equipped with a USB bus, a well-known and commonly used PC standard high performance interface. This interface is used for configuration, testing, and monitoring of the CTS 3000 providing a simple and easy to use user environment for the new equipment. The paper will introduce the new equipment and will show the application in the TEXUS/MAXUS project.
