According to Khabaronline, an Iranian news agency, During the orbital tests, all three satellites entered the phase of subsystem performance evaluation, and their overall conditions were reported as favourable. Due to an issue that occurred during the orbital injection of the Paya satellite by the launch vehicle, special attention was given to stabilising this satellite, and the necessary corrective measures were carried out with high precision.
Paya Satellite Testing Status
The Paya satellite has successfully completed tests of its power supply and distribution, thermal management, telemetry and telecommand communications, positioning, stabilisation, attitude control, and pointing subsystems. Currently, testing of its imaging communication subsystem is in progress.
Kowsar Satellite Testing Status
The Kowsar satellite has successfully completed tests of its power supply and distribution, thermal management, telemetry and telecommand communications, positioning, and stabilisation subsystems. It has now entered the testing phase for its attitude control and pointing subsystems.
Zafar Satellite Testing Status
The Zafar satellite has successfully completed initial tests of its power supply and distribution, thermal management, positioning, and telemetry and telecommand communications subsystems. It is currently undergoing supplementary tests on related subsystems.
Its rotational stability has been evaluated as satisfactory, and upon completion of ongoing tests, evaluations of attitude control and data handling—including transmission, storage, and retransmission—will begin.
Step-by-Step In-Orbit Testing Process
Satellite in-orbit testing is a detailed, phased process carried out over several weeks after launch, during which the performance of each subsystem is gradually evaluated under actual orbital conditions. According to the planned schedule, summaries of technical measures and results from these tests will gradually be made available to specialists and space industry enthusiasts.
