Flight test of 4-Hz and 30-Hz Omega receiver front-end

In-flight information was gathered on two Omega receiver analog modules, one having a 4-Hz bandwidth and the other a 30-Hz bandwidth. The Mini-O receiver was also monitored. An improved signal-to-noise characteristic of the narrower bandwidth front-end with negligible loss in dynamic range indicates that the 4-Hz front-end is the more desirable for the prototype Omega receivers. The Mini-O receiver was found to function quite satisfactorily on its second test flight, and has a very real potential for a low-cost, low-power, compact and light-weight Omega receiver.
