Original Response Date: April 23, 2021
The Space Development Agency (SDA) is seeking industry feedback on the design and development of mission-capable space vehicles for the National Defense Space Architecture’s (NDSA) Tranche 1 Transport Layer (T1TL), including feedback on industry’s ability to support a homogeneous constellation design to provide the full suite of Transport T1 capabilities. T1TL will provide an initial warfighting capability through persistent regional access to low-latency data transport services.
SDA expects the T1TL constellation to feature 6 near-polar circular planes with tens of satellites at 1000 km altitude in each plane.
