After all testing of the systems which we estimate will take 3 months to be on the safe side. Maybe less. After completion of all tests. Reports will be welcomed as we will only be able to see the S/C five or six orbits each day. The command station is 4X6EM at the Haifa TECHNION. Operator in charge is Asi 4Z7ABA and Igaal 4Z7EBA.
