Summary
BULGARIASAT-1 (OBJECT_ID: 2017-038A), also known as BulgariaSat-1, is a communication satellite built by SSL using the SSL-1300 bus configuration and launched on June 23, 2017. It was launched from LC39A at AFETR (Cape Canaveral) aboard a Falcon 9 launch vehicle with a launch mass of 4,000 kg. The satellite measures 5.6 meters in length, has a diameter of 2.8 meters, and spans 31 meters when its solar arrays are deployed. It carries 3 Ku-band FSS transponders and 30 Ku-band BSS transponders for communication purposes. Equipped with two deployable solar arrays and batteries for power, the satellite has a dry mass of 3,000 kg and is designed to operate for at least 15 years, with a projected lifespan of up to 18 years. It was owned by BGSAT (Bulgaria Satellite Company) and was intended primarily for communication services over Bulgaria and adjacent regions.
