Tranche 1 Transport Layer A 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 OrbitCAS500-2 is the second of two similar South Korean Earth observation satellites. These spacecraft feature the AEISS-C imaging system with a ground resolution of 0.5 m in panchromatic mode and 2 m in color mode. CAS500-4 is a wide area Earth-observation satellite with a wide-area electro-optical camera (swath width of 120 km and resolution of 5 m) to be mainly used by the Rural Development Administration and the Korea Forest Service for observing crops, agricultural water resources and forest resources.
Sun-Synchronous OrbitTranche 1 Transport Layer E 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.
