Tranche 1 Tracking Layer C is one of five missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Tracking Layer constellation, which will provide global indications, warning, tracking, and targeting of advanced missile threats, including hypersonic missile systems.
Polar OrbitTranche 1 Transport Layer D is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites. The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance.
Polar OrbitInmarsat-7 is the seventh generation of satellites for the London-based global mobile satellite communications operator Inmarsat. The three satellites of the series - GX-7, 8 & 9 - will have an improved fully reconfigurable Ka-band payload for Inmarsat's Global Xpress services. They are optimized for real-time mobility and feature thousands of dynamically-formed beams that direct capacity with laser-like precision over high-demand areas, to provide HTS (High Throughput) broadband connectivity for the mobility market. The satellites will be based on Airbus’ new standard and fully reconfigurable satellite product line OneSat. Fully reconfigurable and featuring on board processing and active antennas, the three Ka-band spacecraft will be able to adjust their coverage, capacity and frequency.
Geostationary Transfer OrbitCHORUS is MDA's next generation Earth observation constellation, consisting of 2 radar satellites (C-band SAR and X-band SAR), in a 53.5 degree 600 km altitude LEO, with the X-band trailing the C-band by 60 minutes. A collaborative multi-sensor constellation, CHORUS will bring together diverse and unique imagery and data sources and provide a new level of near real-time insight and innovative Earth observation services. Operating in a unique mid-inclination orbit, CHORUS will be able to image day or night, regardless of weather conditions, with daily access of up to 95% of the coverage area. From an industry-leading 700km-wide imaging swath down to sub-metre high resolution, CHORUS will provide the most extensive and unrivalled Earth observation radar imaging capacity available on the market in a single mission.
