GGPEN Begins Maintenance on ANGOSAT-2 Control and Operation Systems

The Angolan Management Office of the National Space Program (GGPEN) has begun maintenance work on the control and operation systems of ANGOSAT-2. This activity comes within the scope of the ANGOSAT project and the Russian Party’s responsibilities. The maintenance activity is taking place at the Satellite Mission and Control Center (MCC) at Funda.

The activities in progress include conducting visual inspection, verifying the operating status and observing the performance characteristics of radiofrequency equipment and the entire information technology infrastructure installed in the MCC. The ongoing maintenance also complies with the recommendation to perform a pre-assessment of the state of readiness of the installed infrastructures for the launch phase of ANGOSAT-2, scheduled for 2022.

The current maintenance of the radiofrequency system is also vital. This is as the infrastructure will be responsible for the communication between the MCC and the satellite. Pending the launch of ANGOSAT-2, the infrastructure has monitored around 96 carriers (communication channels) of satellite capabilities provided to Angola under the ANGOSAT-1 offsets.

The Angosat-2 is about 60% complete and includes innovations and corrections from the Angosat-1. This consists of a transmission seven times than Angosat-1, which had 16 and six transponders in Band C and KU, respectively. Furthermore, Angosat-2 will have six transponders in Band C, 24 in Band KU. Moreover, the manufacturers will add a new relay in Band KA.

Weighing two tons, Angosat-2 will also be a High Transmission Rate (HTS) satellite. It will provide 13 gigabytes in each illuminated region (satellite signal range zones). The satellite will be based on the Eurostar-3000 platform and have a design lifespan of 15 years.

Angosat-2’s construction is at no new cost to the Angolan State. This is because of the insurance package from Angosat-1’s USD 300 million contract. Angola successfully launched Angosat-1 into space on December 26, 2017. However, there was a subsequent primary loss of contact as soon as the satellite entered orbit. The ground station recovered communications but permanently lost.
