ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / A rocket launch, as high dynamics target, was used to demonstrate X-band tracking and also to
verify high bit rate frequency planning while demonstrating significant bandwidth reduction with
IRIG standard advanced modulation methods. X-band tracking by a modified 8-foot mobile
telemetry antenna was excellent. Three separate S-band transmitters with three separate
wraparound antennas were launched as a piggyback payload on an Enhanced Orion sounding
rocket at White Sands Missile Range (WSMR) to compare the performance of 10 Mbs and 20
Mbs bit error rate (BER) pattern data transmission from CPFSK, FQPSK-JR and ARTM CPM
modulation formats under high dynamic conditions. The test is more remarkable in that another
S-band wideband spread spectrum signal was also transmitted with good success. These results
show that all three modulation methods performed well during ignition and liftoff, low aspect
angle (receiving through the rocket motor plume during ascent from a tracker near the launch
pad), spin stabilization antenna lobe fades and payload tumbling. Spectrum pictures are provided
to show the dramatic reduction in transmission bandwidth from CPFSK to FQPSK-JR to ARTM
CPM. Confirmation of the preflight RF adjacent channel interference planning procedures from
IRIG 106-05 is described by spectrum pictures and data quality measurements.
