Imaging

SNC’s Space Systems builds platforms suited for imaging missions, ranging from Electro-Optical/Infrared (EO/IR) instruments and applications, to Space Situational Awareness (SSA) applications, to multispectral and hyperspectral mission solutions. We tailor our bus platforms to support a broad spectrum of imaging mission requirements including high pointing performance and accuracy, minimized jitter, slewing and maneuvering agility and overall platform stability. As an example, our TacSat-2 spacecraft, based on our SN-200 bus platform and launched in 2006, carries a modified commercial telescope and camera system as its primary imaging payload.

TacSat-2

TacSat-2 Program: SNC integrated over a dozen payloads on TacSat-2, including a low-cost visible and near-infrared optical imager with sub-meter resolution.

The TacSat-2 program was the first Air Force flight program to demonstrate an operationally responsive space capability, featuring 14 hosted payloads and experiments. SNC designed, built, and environmentally qualified the TacSat-2 spacecraft bus using the SN-200 platform, and was responsible for both the primary Gallium Arsenide (GaAs) solar arrays and the experimental thin-film solar arrays. The original contract called for two to three payloads, and grew to 14 payloads that were accommodated within the program schedule. SNC worked very closely with the Air Force Research Laboratory (AFRL) customer throughout the TacSat-2 program. Our team completed nine months of on-site bus integration and test, and then supported AFRL in payload integration and system-level test, launch vehicle integration and testing, launch operations, in-orbit test and anomaly resolution. We were able to rapidly accommodate changes in payloads selected by our customer, including a 90-degree reconfiguration of the primary 20-inch optical telescope, while still meeting cost and schedule requirements. The TacSat-2 spacecraft was launched in December, 2006, and met or exceeded all mission requirements.
