S-‐ versus C-‐band experiment at EAFB (1) • Fundamental Ques0ons – Can C-‐band (4400 – 5150 MHz) be used to augment exis0ng telemetry bands? – Do telemetry opera0ons in C-‐band perform in a similar manner as telemetry opera0ons in L-‐ and S-‐bands? 32
S-‐ versus C-‐band experiment at EAFB (2) Aircraft System Aircraft Platform Test Rack in C-12 configured with: C-Band telemetry transmitter (analog) 10W RF power output, PCM/FM, PRBS-11 bit pattern, 5Mbps, f-4515MHz S-Band multi-mode transmitter 10W RF power output, PCM/FM, PRBS-11 bit pattern, 5Mbps, f=2226.5MHz Transmitter outputs are isolated, power matched, combined, 33 and sent through bottom wideband telemetry antenna for
