These instruments provided most outstanding data from which far reaching
conclusions on the nature of the high latitude Heliosphere have been drawn.
Besides these instruments, radio-science investigations will be conducted on
ULYSSES which, at specific times during the mission, made use of the
spacecraft and ground communications systems to perform scientific
measurements.
