He was identified as the offender and arrested in December 2019, before being charged the following July, police said.
Following the sentencing, Det Insp Jones said it had been a “difficult and complex investigation”.
He said Howse had attacked a “vulnerable woman late at night, in a place where she should feel safe to walk home without fear of being sexually attacked”.
He added: “I would like to pay tribute to the victim for the courage that she has shown throughout the investigation; we understand it is not always easy for victims to have to relive an already terrifying ordeal.
“I would also like to say thank you to the selfless woman who came to the victim’s aid after she sensed something was wrong and intervened.”
He said he hoped the sentence went “someway to giving the woman closure and reassures her, and the communities in Hampshire, that justice has been served”.
Howse has also been ordered to sign the Sex Offenders Register for life.
