SOS Pompey are planning to hold a 'peaceful' demonstration on Saturday to call on Balram Chainrai and Levi Kushnir to reveal their plans for the club.
The Blues' joint-owners are pencilled in to attend this weekend's Fratton Park clash with Leeds.
SOS Pompey want to use the occasion to get across the message that they have a right to know what is happening with their club.
As a result, the action group are urging supporters to join in with the demonstration, which is scheduled to take place in Frogmore Road at 2pm on the day of the match.
SOS Pompey are the fans' action group who were behind the successful supporters' march last season and previously met with Premier League chief executive Richard Scudamore to suggest changes to the fit-and-proper-persons test.
An SOS Pompey statement read: 'It is imperative, now more than ever, Mr Chainrai and Mr Kushnir meet with the fans and tell us what their plans are for Pompey.
'Just allowing the club to drift along without a purpose is, for us, a crying shame and something the fans will no longer allow to happen.
'The members of SOS are not naive enough to wish for a successful team with a millionaire playing staff as we have had in the past.
'But we do want is stability and transparency, something which has been sorely lacking from Pompey in the past couple of years.
'While we applaud David Lampitt's attempts at changing this, the proof comes in backing the manager on the pitch as well as saving money off it.
'We appeal for all like-minded fans to congregate at the gates at Fratton Park to join us in a peaceful demonstration of the feeling towards the current situation we are in.
'We are also asking for Mr Chainrai and Mr Kushnir to meet the fans and tell us what you intend to do with Portsmouth Football Club.
'Anything less will be seen as a insult to the fans, staff and players of Portsmouth Football Club.'
