Cosby, a felon who is now officially classified as a "sexually violent predator" for life, will require mandatory counseling and community notifications.
Cosby's maximum sentence was originally up to 30 years behind bars, but when his three charges were combined during sentencing it was reduced to just 10.
Montgomery County Court of Common Pleas Judge Steven O'Neill said he must first rule on whether to designate Cosby a "sexually violent predator" under state law, and arguments continued on Tuesday morning.
Cosby was found guilty in April of molesting Constand, who had been operations manager of the women's basketball team at Temple University, where Cosby had been a major supporter and donor.
Former model Janice Dickinson, who was among the 60 or so women who have come forward to accuse Cosby of drugging and violating them over the past five decades, looked at Cosby and said: "Here's the last laugh pal".
Constand, who is now a massage therapist in Canada, testified during the trial in April and in an earlier trial a year ago that ended with a hung jury, that she had become friends with Cosby, and viewed him as a mentor. He said the Montgomery County district attorney used falsified evidence against his client, pointing to an audio recording Constand's mother, Gianna Constand, took of a phone conversation with Cosby about the assault.
Cosby arrived Monday with his spokespeople, Andrew Wyatt and Ebonee Benson. The judge also declared him a sexually violent predator.
Cosby's lawyers said his age, 81, and blindness made it unlikely that he would reoffend. While the defence asked their client to remain under house arrest pending an appeal, the judge ordered him to be remanded into custody.
The only defense witness expected to testify Tuesday is a psychologist who believes Cosby is no longer a danger, given his age, and should not be branded a "sexually violent predator".
In June 2017, Ms Constand described how Cosby, whom she viewed as a "mentor", gave her pills that left her "frozen" and unable to stop his assault. "He is likely to reoffend", Kristen Dudley, a psychologist and a member of the Pennsylvania Sexual Offenders Assessment Board, testified in court.
The AP does not typically identify people who say they are victims of sexual assault unless they come forward publicly, which Constand and other accusers have done. Cosby did not testify at either of his two trials.
After inviting her to his mansion in Elkins Park, Pennsylvania, Constand said that Cosby drugged and raped her.
"It is time for justice, Mr. Cosby, this has all circled back to you", O'Neill said in court.
"The victims can not be un-raped".
But Steele says it's ridiculous to think Cosby should get what Steele called a "get out of jail free card" because it took this long to catch up with him.
