SpaceX CEO Musk recently revealed the details of the second-generation Starlink satellites. In addition to being 4-5 times heavier, the performance is an order of magnitude higher than the first-generation satellites. Orbital satellite layout.
Musk said that SpaceX has built more than 1 prototype of the second-generation Starlink satellite, which is 7 meters long, has more than 5 times the antenna surface area, and weighs 1,250 kilograms, which is 4 times heavier than the V1.5 version and heavier than the first-generation satellite. About 5 times, the performance is also significantly better than the first generation of satellites.
SpaceX plans to launch 12,000 first-generation satellites, 30,000 new-generation satellites are expected to launch, and second-generation satellites may have to be launched using Starships.
Foreign media Teslarati reported that each second-generation satellite is expected to increase the speed of 140-160 Gbps, which can improve the transmission of the Gen2 satellite network, and the network traffic brought by a single Starship rocket launch is regarding the same as the Falcon 9 rocket launch. 20 times a trip.
According to the report, the Falcon 9 launches 60 first-generation satellites of Starlink each time, and the bandwidth can increase by regarding 1080 Gbps, while the Starship launches 120 second-generation satellites each time, and the bandwidth will increase by regarding 19 TBps.
Foreign media believe that this means that if the coverage is uniform, the total bandwidth of the Gen2 satellite network can reach 1250 Tbps, and the potential economic benefits are huge.
