Pompey will make a trip to Kent to face Gillingham as part of their preparations for the 2022/23 campaign.
Neil Harris’ side were relegated to League Two on goal difference after losing to Rotherham on the final day of last season.
The friendly contest will take place at Priestfield Stadium on Saturday, July 16 (3pm kick-off).
Danny Cowley is also taking his team to face a trio of local non-league outfits, while more matches are due to be announced.
After two weeks of work on the training pitches, the first game is against Havant & Waterlooville at Westleigh Park on Saturday, July 2 (3pm kick-off).
The Blues also go to Privett Park the following day (Sunday, July 3) to take on Gosport at 3pm, with the squad likely to be split across the two fixtures.
The squad will then fly out to Spain and be based in Murcia for a training camp. It is planned for that to conclude with a game, with more information to be announced in due course.
Meanwhile, a Pompey XI will travel to Nyewood Lane to face Bognor Regis on Wednesday, July 20 (7.45pm kick-off).
The club are also finalising plans for a fixture at Fratton Park on Saturday, July 23 – which is a week before the new League One campaign begins.
