Abstract
Abstract A re-entry body telemetry system which uses a solid state delay device to delay selected channels of telemetry data to be retrieved at a faster rate after re-entry blackout. The system also transmits data whose frequency bandwidth is greater than standard IRIG bandwidths.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
86 words
A re-entry telemetry system comprising: means for converting input data to an output pulse code modulated (PCM) bit stream; a first means for RF transmitting said output PCM bit stream; a solid state delay device to store selected data from said output PCM bit stream, and then to output said selected data repeatedly at a faster bit rate; a second means for RF transmitting said selected data output from said delay device; and means for combining and radiating the outputs of said two RF transmitting means.
Claim 2
Dependent Claim
86 words
A re-entry telemetry system comprising: means for converting input data to an output pulse code modulated (PCM) bit stream; a first means for RF transmitting said output PCM bit stream; a solid state delay device to store selected data from said output PCM bit stream, and then to output said selected data repeatedly at a faster bit rate; a second means for RF transmitting said selected data output from said delay device; and means for combining and radiating the outputs of said two RF transmitting means.
Claim 3
Dependent Claim
82 words
A re-entry telemetry system as recited in claim 1 further comprising: a voltage controlled oscillator (VCO) having a frequency which deviates from a center frequency depending upon an input data signal voltage; means for mixing the output of said VCO directly with a wide frequency response data signal; a third means for RF transmitting the output of said mixer; and means for diplexing the output of said third transmitter means with said second transmitter means prior to said combining and radiating means.
Claim 4
Dependent Claim
26 words
A re-entry telemetry system as recited in claim 2 further comprising means for turning on said second and third Rf transmitting means just prior to re-entry.
