Spacecraft data:

Description:

• Each second-generation Globalstar satellite weighs approximately 700 kg, offering end-of-life power of 1.7 kW. It is fitted with 16 transponders from C- to S-band, and 16 receivers from L- to C-band. Each satellite has a design life of 15 years.
• The satellite body is trapezoidal in shape with two deployed solar panels, in order to allow multiple satellites to be carried on the same launch. The wider side of the body that faces the sun in flight holds L-, S-, and C-band antennas communicating with gateways and phones.
• Globalstar’s 24 new second-generation satellites will be integrated with the eight first-generation satellites that were launched in 2007. The new constellation secures the company’s space segment through beyond 2025.
• Once fully deployed, the advanced second-generation constellation and next-generation ground network are designed to provide Globalstar customers with increased data speeds of up to 256 kbps in a flexible Internet protocol multimedia subsystem (IMS) configuration. Products and services supported are expected to include: push-to-talk and multicasting, advanced messaging capabilities such as multimedia messaging or MMS, mobile video, geo-location services, multi-band and multimode handsets, and data devices with GPS integration.

Mission details:

• The second batch of six second-generation Globalstar low-orbit communications satellite was launched from Baykonur on Jul 13 into a 920 x 932 km x 52.0 deg parking orbit.
