International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / A small PCM telemetry system designed for the flight test telemetry task of a new rotorcraft is introduced in this paper. It can provide a flexible frame format which is completely set up by user in advance, to meet the requirements needed in different flight testing phases. In this telemetry system, the data are low in rate and volume but very valuable with stringent quality and transmission accuracy. Data encrypting and channel encoding techniques are employed to guarantee the quality and security of the data. The system architecture based on microprocessors is adopted in order to process the data flexibly. Real-time data processing, monitoring and post-flight analysis are performed by PC type computers. All key components of the system may be programmed. The cost of the total system integration is relatively reduced.

International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / In this paper, it is introduced that a C-Band mobile telemetry system designed for the satellite telemetry task. It can provide a wide range of bit rate and different code type and frame format which is completely set up by user in advance, to meet the requirements needs in different satellites. The PCM-PSK-PM signal and the PPM-MFSK-PM signal can be received and demodulated at the same time. Single channel monopulse technique is employed for automatic tracking. Angle calibration and angle tracking are performed in this system. Real-time data processing, displaying, testing of bit error rate and post-flight analyses is performed by PC type computer. All key components of the system may be programmed.
