Evaluation of a quarterwave stub antenna for TIROS satellite application

"The capability of a marine mammal transmitter to provide data to a satellite receiver to calculate accurate position information was demonstrated using the NIMBUS random access measurement system (RAMS). However, NIMBIS is nearing the end of its design life, and emphasis is being shifted to TIROS which has a similar acquisition system but will require modifications to the transmitter package. The NIMBUS sensor requires 980 m sec to complete an up-link, while the TIROS system will require only 360 m sec, which should improve system performance because of the uncertain dolphin breaking cycle"--Summary, paragraph 1.
