SSTL GMP-D

400 - 1000kg Direct Injection Orbit

Ideal for shorter duration missions, the GMP-D is our entry level platform.  The low launch mass and SSTL's rapid schedule offers customers cost-effective delivery of small payloads into geostationary orbit, exploiting occasional low cost direct injection launch opportunities. 

SSTL's GMP-D platform is also suitable for non-geostationary communications and navigation applications.  Its first flight was as GIOVE-A, Europe's first GNSS satellite, launched in 2005 and still performing well in 2010, having exceeded its mission lifetime by over a factor of two.   

SSTL GMP-T

2000 - 2700kg Transfer Orbit

Our core Geostationary platform, the GMP-T offers a highly cost-effective solution to your operational needs, combining SSTL's heritage reliability and rapid delivery with flexible payload capacity and launch opportunities.  The platform has been designed to maximise capacity and performance and accommodates either industry standard or custom-built payloads.

Key Platform Characteristics 

SSTL are currently growing the capability of this platform to accommodate payloads of up to 300kg.

GMP-L

1400 - 1600kg "Lite" Transfer Orbit

The GMP-L is our compact geostationary product offering more modest payload capacity.  It is designed to enable customers to take up cost-effective dedicated launch opportunities on the Cyclon-4 and Falcon 9 vehicles, and co-passenger slots on the Zenit. 

The GMP-L's hybrid propulsion system design maximises payload capacity and lifetime making it ideal for applications such as initial service offering, augmentation of existing service or frequency filing protection.
